Does anyone think the last two pictures aren’t cal/mag deficiency?

@OutForRealbeanCarib, thank you for the reply man. I’m sorry for the awkward reply hours. As I am on the other side of the world. The hydroponic nute we have in our country are very limited, and definitely not geared towards weed. The veg nutrient I have is a local veg A/B mix, at 8-4-12 NPK ratio, with 11% CaO, and 4% MgO. That’s all it says on the packaging. I’ve tried calling the company, but they aren’t willing to divulge any more. I do have access to extra nitrogen fertilizer if needed, as well as 0-10-10 fertilizer. I also have access to other chelates for micro nutes. Right now, I am mixing the nute at 2 ml/L for each A and B. Is this the info you needed?

@JKT48,Hey bro , can you fill your nutrients values and proportions for us to help you?

Problem was solved! It turns out, it wasn’t a nutrition deficiency. My Optic4 LED grow light was just too close for this young thing. Even though it was already 4 feet away from the canopy. Yep that’s right, 4 feet was too close. So I raised it to 5-1/2 feet and the new growth started growing with a darker green, and the previous leaves’ damage did not spread any further. I came to the light distance conclusion because I saw that the fan leaf stalks were purple; but only the top half! The bottom half of the stalk that was hidden from the LED’s Ray was normal green. Now, I don’t know if it would do the same if it was nutrition deficiency, but seeing that made me think it was the grow light distance. And it was.

how tall is your tent because this strain grows just about twice as its size.. on top of that, you're growing in a dwc. it'll grow really tall.. get ready to super crop this thing.

@MaryJaneUSA, got it. I will definitely do that when the time comes.

@MaryJaneUSA, yes sorry for the misunderstanding. I know how supercropping works. So if I do it to a flowering cola, then what I will have is a crooked cola with a horizontal-ish section at the top right? I wouldn’t mind that at all; it’s for personal use after all. It’s just I’ve never done supercropping during flowering.

@CRiSPrGrow, so it turns out, the calcium supplement I used before already has magnesium as well; but they were in powder form it turns out, they were meant for soil, and when used in hydroponics they clump together. It forms a white precipitation. Gypsum I’m guessing. So now I dissolve the calcium nitrate separately to the magnesium. So far this week it has worked out well. No new ugly leaf like before. Thank you for your input!

@JKT48, excellent question bro, you're correct it's not directly available it will need to be chelated (with a chelation agent) or like you said use the nitrate.

Did you use any spray? About harvesting readiness I think your plant has a chance and a bit more time for a little more fattening up and getting stronger. Wait until trichomes on a representative middle buds starting to become yellow.

Med_in_Tropiccommented6 years ago

@JKT48, yes it is exactly what I meant. I had the same burnt and same brown pattern on my plants when she was in late flowering . And I thought it was from either my foliar spray feeding or tobacco tea. Guess it’s just the time that plants pool back nutrients from leaves towards the end of flowering . Good news is you’ll have your harvest soon enough . Trichome looks like it can go at least a couple more weeks though.

@Med_in_Tropic, no, I havent been using any sprays. Not for pests (I have no pest issues), nor do I do any foliar feeding. Is this what you mean?

Hey man, great grow. I wanna do scrog next grow as well. Can you share a picture from under the net. Would love to see the height between soil and net.

JKT48commented6 years ago

@ChronicFinest, yep it’s confirmed 6” below the net and above the Rez. But I do not recommend doing it that low. It’s so hard and awkward to reach the back of the plant. If I can do over, i’d go 1 feet minimum.

JKT48commented6 years ago

@ChronicFinest, for sure I will, when I'm back next week. I'm keeping this really low. probably about 6 inches only.

plantiecommentedweek 136 years ago

Day 90 bright yellow new growth only zinc deficiency 100% . you got to look online find a reputable breeder that you trust and download a leaf cue chart . lots of pro breeders have decades of experience and some have leaf cue charts that will show you all possible toxicities and deficiencies . download one print it off stick it up beside your plant . i go by a chart like that its never let me down i act really fast and my planties are really healthy for it . just some advice i think you need . plants can be deficient in many trace minerals you would be amazed like iron zinc calcium manganese magnesium and more . your plant looks good tho . i guess im trying to say a quick refrence guide is key . hope you get an awesome harvest !

@plantie, thanks man! I'll take that piece of wisdom for my next grow. At this point though, I'm already halving the nutes anyways, gonna harvest sometime next week. Really appreciate your looking at my previous weeks!

MarcXLcommentedweek 176 years ago

No, i even didn't know that disease existed. But I found that about it:This fungus spores may stay in the soil over the winter, and attack your plants in the summer. Spores are also easily spread by wind and rain.Immediately (and carefully) remove all affected leaves to get rid of as many spores as possible.Prune any leafy parts of the plant to improve circulation through the plantAvoid getting water on the leaves or laying on top of each other – you want to avoid moistureMake sure to keep the ground under your plant clean. Rake away all leaves and vegetation. Adding mulch can also help prevent spores from spreading.Keep plants healthy, sicks plants are much more susceptible to leaf septoria than healthy plantsOne way to help prevent this fungus from attacking your plants is to rotate crop sites or move to a new location every year.A broad spectrum fungicide may be effective at stopping the fungus from spreading though they are best used as a preventative.Depending on exactly what's causing your leaf spot, mister (also called a "One-Hand Pressure Sprayer") to spray all the leaves evenly, since neem oil and water can separate easily. Try spraying just a small part of the plant and see how it reacts first before spraying the whole thing.Hope it may help you

@MarcXL, Either way, I chucked the one with the hideous spots. And since last week, I pH-up the rez every day or two. The pH keeps dropping fast. But since then, the leaf problems have at least slowed down, if not stopped entirely. Thanks for your help man!

@GreenHouseLab, Thank you! I wanted to fill up the whole tent, but it seems the plant wants to radiate out in a circle shape, so I think this is it. I'll be back from my trip in 1 week, and I'll flip her into flower. Well... let's hope its a she.

@JKT48 wrote “ I can't be sure because I can't open the tub anymore due to the scrog net being on there.” Both this prohibitive result, and the extra work to install a scrog, have been deterrents enough for me to never attempt it. And also I believe people just love to tinker with their plants, but I haven’t seen a side by side comparison of scrog to free grow that would prove or disprove its touted benefits of better bud and more of it. I just read a piece in Big Buds Mag that explained why it’s not a good idea with autos specifically, because they have a pre programmed veg phase we can’t alter. Your business trip is a perfect reason to train her for sure! Here’s hoping the brutal session wasn’t brutal on you! Your crop looks to be fantastic. Complimenti Best wishes in both business and bud!

@growdoctordc, yeah, I guess the biggest downside with scrog net is how you really can't move the tub's lid afterwards. But i think next grow what I'll do is modify the lid to have multiple windows that can be opened and closed. We'll see.

Yo i took a look at your leaf pics there in week 7 the darkness tells me there is a buildup of nitrogen the tell tale sighn is the curling of the serated edges and curving of leaf tips . thats untreated nitrogen toxicity i believe . the plant will store excess nitrogen in the big old fan leafs first . un treated they turn really gnarly . if it was a deficiency it would effect newer growth too . i believe bright yellow lower fan leafs is nitrogen deficiency . calcium deficiency starts as light circular dots and is not limited to lower leafs however nitro toxicity will eventually turn colour like that if untreated . they will even resemble potassium deficiency if left long enough . just my opinion tho . looking good in the later weeks bud good growing !!

Day 119 think its got the claw again lol watch the nitrogen input . just my opinion tho . if you keep hitting that problem just lower the nitrogen especially in flowering stage the plant needs p k to bud n is mostly for veg and root growth . looks like a few upper leafs show a k deficiency . just trying to help 😊

You have about another 2 weeks left. No plants are perfect, leaves will discolor as they are the end. Slowly reduce your nutrients. In about a week and half later, go ahead and start flushing your DWC for about good 2-3 days. You should be good to harvest.
