Haze - transplant to 5 gal pot, water. a few days later noticed some more yellowing. been a week since last feeding. mid/upper 1/3 brown tips that are curling up. i think its a mag def, so i fed 1/2 epso1/2 full feed mix 2.
Kush - mostly dead. feed mix 3 + epson salt.
candida 1 - looked way too crowded. transplanted midweek to 5 gal fabric pot. some of the bottom leaves are brown,yellow,dying. mid 1/3 yellowing edges and btw vein/edges. feed 1/2 epson salt mix, 1/2 mix 2.
Charlottes angel 1 - top 1/3 darker green, lighter edges, yellow tips. bottom 2/3 - yellowing edges, tips starting to brown,curl up. feed epson salt _mix3.
Char angel 2 - few bottom leaves necrosis where they touched the soil I think. feed mix 3.
Candida 2 - dull rich green, new rich growth. full feed mix2, epson salt.
All 3 failed grows use organic soil/perlite, fabric pots.Each grow, Tried more/less water, and more/less nutes. I'm using GO Box nutes this time. Same problem as always - bottom leaves lighten at leaf edges, veins stay green. Leaf tips brown, crinkle, travels up leaf, up plant
Hey there, just a couple things, i see you mention fungus gnats? Id try getting some of those square sticky papers to put at soil level, itll catch a good amount of bugs. Usually gnats hint at high moisture. You could also turn loose some predatory insects like lady bugs and pirate bugs.the neem is good for getting the larvae so less hatch and become adults. What soil are you using? Most decent soil has enough nutrients for at least a couple weeks. I hope everything gets a bit better, usually time will tell. Possibly check the lights if you think its not ph or nutrients, they can cause as much spotting and burning as any toxicity/deficiencies. Best of luck, dont give up!
If you failed in different setups, and everytime the same happend, then the Mistake is not in the Setup or the Plants. Well how to say it nice and clear in one.....Try to summup the Informations youve got and Handle after the Recommondations. I see Only discussions and no handling of the Problems. Ok said....
@GreenChick, im a grateful grower fan as well.. kinda disappointed he hasn't uploaded any new videos. but try nebulahaze on www.growweedeasy.com, she will teach you literally every thing you need to know about growing.
kraut, my first failed grow, I thought I overfed them, so I backed way off on my second failed grow, and they did worse. after looking at other candida entries on this site, I noticed some growers were using very high levels of nutes. so that's what I'm trying on this grow. Each time I feed them, they seem to be getting better. the levels I'm using are from the box, which I know people say use 1/4 or 1/8, but that didn't work last grow.
thx for the tip about the lights and roots. makes sense.
toadiek - I'm using some premix organic soil from Lowes. It seems really low on nutes. they don't give % on the bag, only ingredients. I didn't start feeding any of these plants until about the 3rd or 4th node, and only after noticing a little yellowing starting to form.
@GreenChick, Hm your soil mix sounds good and it seems that you use cal mg right with your ro (unfortuanly i have no experience with RO).
Unfortunaly i have no more idee what is causing your issues 🤔
I recommend to use your grow question. Im pretty sure some experienced growers will help you 👍
I keep following your grow, just dont give up, we only learn from mistakes 👍✌️ best wishes
@KrautFabrik,
I don't know what it is. I've read books, blogs, videos about these issues. I thought that any lightening/yellowing was usually a nute deficiency. And that this type of yellowing was usually a calcium def. I am using RO water, ppm around 20 before I add nutes. I've been watering/feeding about every 3 days, and the top 1/2 of the fabric pots are bone dry, but heavy/wet on the bottom 1/2.
Yesterday, I watered in a ring around the plant, rather than directly at the stem, thx to a suggestion by hufflepuff.
Based on my last two failed grows where I don't think I fed enough, this time around I'm trying to make sure they get their nutes. I didn't start feeding until I noticed some yellowing on leaf edges (week 3-4?).
My soil mix is 3 parts organic soil, 1 part perlite, 1 part vermiculite. I wanted the extra drainage due to my overwatering problem on my last grow.
As I understand it, the most common nute deficiencies are calcium and magnesium. That's why I think that the upward leaf curl at the edges are a MG def, which is why I've fed a light epson salt feed about every 2 weeks so far. That's the problem that's killed every grow to date: brown, twisted upward leaf curl, brown travels up the leaf until the entire leaf is brown, crunchy. Then same problem moves up the plant. I can show you pics from my other grows if you want.
Thanks for your time and input. I just want to grow some back medicine, but this has been discouraging me for over a year now.
@GreenChick, i'm really sure this is a nutriets burning caused by cal mag. Last year i tried the first time cal mag at a guerillia grow and only 2.5 ml at the beginning of flower killed a 1m tall cheese autoflowering. I believe you dont need cal mag if you use soil and tap water. It makes only sence if you use RO or distilled water. (I only use it in the first 1 or 2 weeks of flower as some extra).
I would recommend to flush them and wait a week to see if they recover. And give them less water, let the soil dry befor you water again, the roots need air too ✌️
I know that some growers use a high nutriets level but i would recommend to every beginner to start with no nuts and only feed them if there is a defizit. You may get not the biggest yield but you will learn a lot about the plants needs in each part of Life cycle.
As i started my first Outdoor grow (with pots) some years ago i didnt use any nutriets and had only some N defizit at the end of flower. And yes the yield was good too. 😂
And for future grows i recommend a good all mix soil with some extra perlitte. You will need a longer time no nutriets and less problems. (you can easily veg 8 weeks without anything). Only the first 1-3 weeks i would use a small pot with some soil with less nutrierts/light mix.
This year was the first time i used cheap soil for my balcony grow and its the first time i have to deal with much nutriets issues -> i will never use a cheap soil again 😅
Best wishes and keep going 👍

You’ve been offered excellent advice here by top growers that should remedy your issues, if not this time, certainly in future. Keep growing! One day it will click
Hi @GreenChick! My guess is that wrong pH, high temperatures, under-watering and too many nutrients led to this situation. Why are you working with this pH? You should stick to a 6.0-6.5 pH range so the plants will easily handle nutrients intakes. In hot environments, plants can't handle heavy nutrients doses and soil develop salts buildup. Do you check your EC? If so, what EC have you been applying for the last weeks? 13ml/L is way too much, especially when the plants are already unhealthy with burnt tips and crispy leaves. Under-watering might be involved too, if you gave 0.38L everyday for a 11L container, that was obviously not enough. Roots need to be on a wet/dry cycle to properly search for water and spread. When watering, always water with ~20% of the container's volume, keep on watering until you see the runoff coming through the bottom of the container. The runoff will help you to diagnose your issue, if you can measure its pH and EC. Finally, if you encounter issues each time you grow, you may consider posting a daily update here on GD, with all the details about your feedings/measurements/temps so we'll be able to help you adjusting your parameters. Keep us up-to-date and happy growing 👊
@Stick,
my first grows were pH'd to 6.0 and it went south each time, BUT, maybe other factors contributed as well. It's hard to pinpoint the problems, when it could be one thing or 6 things. Do you think I should apply every suggestion you had at once, or process of elimination by 1 at a time? I'm concerned that if I change everything at once, (like I did my last 2 failed grows), then the problems may persist and I won't be able to narrow it down.
My watering dilemma is that the bottom of the pots are pretty heavy, but the tops are bone dry. If I continue watering at a normal pace, will I root rot the bottoms? (My first grow I think I overwatered to death).
Previously I measured the runoff, and it measured about 6.5.
I need to figure out a fan situation to cool it down. Right now I have one fan at the top, blowing down on the plants, gut it's also circulating hot air. Today it was 90 F in the tent. Great comment about the hot environments and heavy nutes. I didn't know that.
Okay, In terms of clones, when you cut them, rooting them in a rooting gel and then putting in a rapid rooter, then put it in a humidity dome until you start to see roots, is the most effective way to go. Because you don’t have roots yet, you need to foliar feed constantly until you SEE the roots, usually takes 1-2 weeks. Once you do that, you can transplant it but you can also add beneficial microbes such as mycorrhizae around where the roots touch for symbiotic relationships. Then you can water the soil and the roots will start absorbing nutes. Clone growing is very different from regular growing from seed. You need to feed the clones more than what you would do for regular plants because we have to think about the motherplant’s age Genetics (which you cloned from). Also if your motherplant looks sick and you clone it, likely you’re going to have sick clones unless you can get them healthier. Or if they’re sick and you pick out clones, the sick motherplant may stunt itself. To me, it may have early signs of magnesium or phosphorus deficiency. If you’re worried about yellowing all the way on the bottom, it usually is that way because it’s not getting light. But if the yellowing spreads from bottom to up, you have nitrogen def.
@MaryJaneUSA, I'm using RO, since my well water was running about 380 ppm. RO brought it down to about 12ppm. I have a soil ph tester arriving today. And I'll buy another ph tester today from amazon. But you have to agree to continue checking in with me.
Update on this week: I finally got a LED shop light, 6500k for clones, so I moved a tray of dead clones from my veg tent, under the shop light, and about 5/10 are recovering. Amazing, the difference the right light can make.😶
It looks like you are getting a lot of good help here. You may want to get your clear plastic cup there covered. Either with another colored cup or maybe wrap it with tape like I do. light is not good for roots.
Some thing I found I had issues with. My plants looked similar to your was having to hard of water. It will look similar to a cal mag deficiency. My water is 535ppm here. I use a 50/50 mix of tap water and RO water. I am in coco and use the GH nutes. I use there hard water micro with the 50/50 mix. One item I found really helped my plants was armor si. It really helps with your plant up takes even when room conditions are not the best. heat and humidity wise. If it were me. I would also get these out of those little cups and into at least a 1 gallon pot. I really think that would help you out too. I am not trying to tell you how to run your grow. just things I would address if this was my plants I was dealing with. Over all. it looks like things are going good for you. I also saw you had fungus gnats at one point. i got rid of some I have with one dose of dawn dish soap and water. about 5 drops in a 16 oz spray bottle. Worked great for me. I will be following along here 😉
@GreenChick, With cal mag. You can give a lot more than is required and not hurt your plants. it is just costing you a bit more. My first grow. I used 1 tsp per gallon. I found 1/2 that was more than fine with straight ro water. 5ml = 1 tsp
For wanting to see your roots. That is an easy fix. I do the same. Just take another clear cup. Wrap it with tape so you can't see into it. Cut the bottom out and slide it over the cup your plant is in like a sleeve. Any time you want to check your roots. Just pull the first cup that the plant is in up. And you now can see the roots 😀 I started using the armor from a friends recommendation. It really is great stuff. I run it regardless of what my nutes may have in them.
There is nothing wrong with wanting to see through for making a decision in my book. Any advantage you can get to make growing is a plus for me. 👍
@justright, Thank you for the thoughtful reply. the only reason I use the clear cups is to see if the roots are growing alright, but I get your point. As I SLOWLY get better as a grower, hopefully I won't need a visual to help me to make decisions.
My water is RO, but I add 5ml of CaMg+ per gallon, from GO Box. Do you think I should go over the recommended because of my RO, or stick to their recipe?
Armor SI looks interesting. I'm not sure if any of my nutes already has silica in them. I'm using GO Box, Azos and Mykos. I know my bloom mix has potassium in it.
This looks like Nitrogen deficiency. I don't think you are supposed to be giving them the weed, bud, and bloom nutrients all at the same time. In fact I checked the amounts, you aren't supposed to be giving any bloom nutes, and I think your weed nutes are too low. My guess is might be overwatering, with wrong ph, and too much of wrong nutrients. They need classic NPK, and I would also do the calmag at low dose. Make sure you get the ph correct at 6.5, this is most important. Put some holes at bottom of cups to make sure they fully drain. Get them into bigger containers as soon as they establish a root system.
@BeefWellingtons, I probably didn't make it clear in my entry. I have a flower tent and a veg tent.
The bloom nutes I listed were for the flower tent only. That mix is bloom - 10ml, camg - 5ml, bud - 2.5ml, marine 10ml.
veg tent is grow 10ml, camg 5ml, root 10ml, weed 5ml, marine 10ml.
Then I'll dilute it to my description - ie 50% str, 60%strength.
But you bring up a good point about the ph. My soil is running about 7-8ph, but my RO is about 5.9-6.1. I thought that the lower RO would balance the higher soil.
@Mrs_Larimar, thx for the suggestion. I've been spraying soil once a day at the beginning of the light cycle. After 3 days, I've noticed considerably less gnats.
the burnt tips is the first sign of nute burn if you're leaving them in veg you want to keep nutes a tiny bit lower that's all... try some larger pots if you can, they'll need the space to grow
Hey dude,
I think you overfeed them. If you use a good soil you dont need nutriets for the first 4-6 weeks of veg. And special cal-mg, its way to much.
The plants in the cups are overwatered and i wouldnt use a clear cup because roots dont like lights. ✌️
Good luck 👌
Hey green so i was reading your week and i was curious are you using a ph pen? Because if all plants are suffering possibly its ph, or root related? I did my ph based off my water report..so i could have been wrong, my ph probably changed over the grow season.
@Experimentgreen, I just ordered some testing powders yesterday and should have them soon. So, weird coincidence - My first pen started working briefly, and both pens (which had been calibrated) showed my RO water as 5.9, while the drops color chart showed closer to 6.5. If you look at the picture I'll post in a few days comparing the pen to the color chart, what do you think? Am I partially color blind?
In the meantime I've been foliar the two yellowing clones with calmag and they're just getting worse. Yesterday I flushed them, and the ppm was only about 140. So not nearly enough nutes right?
@GreenChick, I think this is like déjà vu, I had bought a brand new set a ph and ppm and IA dial them in with the powders they were working good and all the sudden they went on the Fritz and were reading crazy numbers. It's probably good that you ordered another one just in case but if they take batteries I would almost say I'm try switching out the batteries and retesting them that's what I did not do and I should have. Do you have any extra testing powders? If not I know you can measure things like pure/distilled water should have ph of 7.
I checked with my water company and our hose water is roughly 6.8 and my ph pen had confirmed that, so when it went crazy i just stuck with it...but i need to pick up a new one that's a little better quality i think.
@Experimentgreen, based on another recommendation, I bought a second ph pen, but it reads my RO as 5.7, while the drops method shows 6.5. So I'm thinking about buying some ph buffer powder. And yes, I used the powder that came with it and thought that I had correctly dialed in my ph readings. I know the soil ph meter I got reads about 8ph, but the runoff was reading about 6.5. What do you think?
@Tonino, I randomly decided to test the ph of my feeds and found that it was hovering around 4.5 - 5.0. I never checked this before because the GO BOX said it wasn't necessary to ph my feed. Do you think this is contributing to some of my problems?
@Stick, I've been working on that. My issue is that while the top inch might be dry, below that is heavy and wet. I don't want to risk drowning my plants like I did on my first grow. Do you still think I should water when the lower 1/2 pot is wet and heavy?
Also, I've read that it's better to underwater than it is to overwater. Do you agree with that?
Thanks for the input. The more the better, as I'm consuming unhealthy amounts of cannabis info and trying to pick and choose what I need to apply. 😀
@Tonino, pretty happy. Wish I could auto-diagnose some of my issues. I'm guessing alot is environment, which I can't really control. My basement leaks every time we get rain, so humidity is always super high, and the basement is pretty cold, but a space heater would just get sucked right out of the room.
