-----------------------
I take photos and add info (height, etc) on the *first* day of each week. Sometimes will add extra info and pics during the week. Temps and humidity are edited later to get an accurate view of the whole week.
Feb 1 / Day 1
Seedlings in rockwool cubes potted in Solo cups.
Prior to this they were in the humidity dome in rockwool cubes only with 5.5 ph water. They are out of the dome and tent only for a moment to transplant them in the photo.
High humidity in the germination dome with Veg light only.
Blurple lights only, COB white lights off for now.
Day 11. Removed humidity dome.
Large drop in temp each night, throughout the entire grow so far. Fixed about midway through the week by adding a small heater to kick on at night.
Start of week temps ranged from the low 80s all the way to the low 60s at night. Fixed temps and got to about 72 day to 65 at night. Humidity about 55
Day 13 Transplanted to larger pots
80F Day
65F Night
Earlier leafs are dry and had glossy spots that turned to yellow. Maybe a pH or nutrient issue after being transplanted to larger pots. Havent found photos of others with this same look to their leaves.
Day 15 - Watered with nutrients for the first time.
Day 16 - Finally added Cloudline T4 inline fan. Previously I had been leaving the top of the tent unzipped to not let the humidity build up too much. Trimmed off of a few of the really dry dead leaves.
Day 17 - Turned on the COB lights on the lamp (and am keeping on veg lights). Because the COB lights are warm, I raised the distance to 26" after reading about another user with the same lamp. Also got a power extension and managed to center the lamp in the middle of the tent (it was previously pretty far to the right side). With the COB on, the T4 fan is having to blow a lot of air out to keep it cool, so the humidity has been much lower. Around 40%.
Day 20 - Raised the lamp again a couple inches which I think helped cool the plants a couple degrees so they could stay barely within the highest acceptable range (81-82 F). Been pouring a pint or two of water onto the floor of the tent to help humidity levels from dropping too much while the lamp is on.
79 F - Day
72 F - Night
35-45% humidity
Plants:
Left - Afghan CBD
Middle - Critical Cure
Right - Moscow Blueberry
Opened a bottom vent hole for the tent which helped the temps from getting too hot.
Day 22 - Topped all plants and watered. Defoliated the 4 bottom stems on each plant (2 fan leaves and 2 branches per plant), as they were completely in the shade. Tested water runoff at 6 pH using test strips.
Day 24 - Further defoliated bottom branches. Needing to water about every other day now. I need to pick the best of each strain and transplant to 5 gal pots soon.
Ive got 6 plants, 2 plants per strain. In 2'x4' closet tent. I plan to choose the best plant of each strain and transplant (into 5gal pots). How do I choose the best plants? Tallest, bushiest, darkest? Example: Blueberry has one dark one and one much bushier lighter colored one.
Hey Growmie ...
When picking a pheno it's suggested to grow out each plant until they are 6-12” tall, or big enough to clone. Of course, you will discard some of the phenos based on their poor quality and keep the ones that have good qualities. After about 8-10 weeks of flowering, these original phenos will be ready to harvest for buds. Some phenotypes might finish sooner than others and each will probably be slightly different. Now you will discard some of the phenos based on their poor quality and keep the ones that have good qualities.
Most growers are looking out for traits such as:
Growth structure: The plant’s height, weight, build, density, and root strength
Hardiness: The plant’s reaction to temperatures, dependence on water, resistance to mold and pests, and overall strength
Terpene profile: The aroma coming from each flower
Appearance: The buds’ color and structure
Trichomes: Either lanky with small heads or short-stalked with fatheads
Peak maturity: How early the plant is ready for harvest
Hopefully, this was helpful and remember ..."Happy Growing" and "Free your mind one puff at a time".
Day 29 - Narrowed it down to 3 plants (1 per strain).
Transplanted from 1lb pots to 5gal mesh bags.
Upped nutrient trio from 1tbs/gal to 2.5tbs/gal.
This week watered 1/3 gallon per plant At first then 1/2 gallon per plant towards end of week. Every other day.
Day 36 - Pulling back from 2.5 tsp to 2 tsp on trio nutes because far left plant has some possible nute burn (yellow tips). Added Cal Mag 1 tsp per gallon as of last night due to Afghan plant looking like it needed Calcium.
Day 37 - Added humidifier. Finally able to get the humidity up.
Upped trio nutes to 3tsp a gallon. Humidifier has worked well in getting more humidity, but I need to replace the distilled water which ran out, so the humidity is low again. It gets in the way a bit. I might need to find a better position for it.
With the warmer weather, I stopped using the heater at night.
Day 50- Plants are looking good. Continuing defoliating in preparation for the SCROG. Continuing to veg until they all hit a decent height and I can raise the SCROG Screen to at least 20”. It is currently at about 16”. If plants get too wide I’ll start flowering. We will see how they look next week.
Humidity low because I keep forgetting to buy distilled water for the humidifier!
Day 57 - Switching to flower cycle! Continuing with the same nutrients but will add Big Bud later.
SCROG is now raised 20” from plant and all plants are hitting it. I’m spacing them out as they grow.
Watering every other day but by the end of the second day they get a bit droopy, especially critical cure. Probably should water a little earlier.
Day 64 - Just continuing the flower cycle. I’m still defoliating anything under the SCROG that looks like it will never reach light. Probably will need to stop trimming this week to not stress them anymore.
They are still on the regiment of a half gallon per plant every other day.
Adding in Big Bud nutrients now, in weeks 2-4. Using 1.5tsp per gallon. That’s all the nutes I’m going to use on this grow.
Finally adding the humidifier back in, as I got some distilled water. I want to get the percentage closer to 50%.
The AN trio and cal/mag have worked fine so far so I’m going to keep it simple.
Day 66 - Early into the second week of flowering, did the last I will do of trimming / defoliating.
I live in a hot and dry desert climate. Tent is around 81F in the day and 65 at night. Is this temp drop a big problem? I have a small heater I can use at night pointed at the tent if necessary. Humidity also a problem (38 in tent) but I am trying to bump it up with a humidifier.
Hey there, I also grow in a semi (ha ha, some say desert) arid climate. I use grow cabinets, in dry ambient room humidity levels.
During the early stages of veg, my levels were always around 25-30%. This did not seem to affect growth rate.
After the plants get big, and more water is used, transpiration (evap of fabric pots as well) added 10% more humidity.
Unless the seed developer recommends a certain humidity range, it really isn't an issue to me.
As far as temp ranges go, I have gone from 80F to 65F, consistently with no issues,with all of my strains.
Some pundits say, no more then a 20 degree diff, between high/low. OF course some strains stop growing at certain low temps, so research your strain, and some grow tips for them.
Day 78 (April 18) - Everything is looking great. Just continuing feeding every other day. Definitely can smell the individual plant fragrances on my fingers if I touch the plants now.
I’m putting the average height as the height in the log at the start of each week (31”) but the tallest cola is probably 34”.
The Moscow Blueberry (middle) is definitely shorter than the other two (Critical Cure on left, Afghan on right).
I added a second (net) trellis, which is definitely unnecessary and over kill, but I wanted to direct some of the taller plants out of the way, and not shade over the shorter plant in the middle as much. Just slightly pushing the colas to the sides for even more light distribution.
I added a small oscillating fan pointed down across from corner to corner just to break up the airflow directions of the other fans.
There were some cold nights last week (tent got in the high 50s at one point), so I brought back the small heater set to kick on in the middle of the night.
This is week 4 of flower so it will be the last week I use Big Bud nutrients.
Day 85 (April 25) - Going well. Plants are almost flawless in all their leaves and smell very good.
Going to discontinue using Big Bud, as I have passed week 4 (as per instructions). I have some water already mixed up but after tomorrow’s watering it won’t be used anymore.
Budding is going well. A few of the whispy hairs have dried and turned red, but very few so far.
Last night I noticed two small LEDs that were lit up inside the tent each night without me realizing (!). One on the humidifier and one on the new small oscillating fan. I covered them with tape.
Left - Critical cure
Middle - Moscow Blueberry
Right - Afghan
Day 92 (May 2) - Continuing on.
Been getting a bit hot in the tent towards the end of the day (tent gets to mid 80s sometimes, even 88F once!) so I’ve been opening the top flap a bit. I also set up another fan in the closet, that directly blows air from the outside of the tent into the tent.
The Afghan and Critical have begun curling their leaves downwards. At first I thought this was from the heat, but I read that typically heat causes them to curl upwards. It may be a nutritional issue; the Critical is starting to turn a little yellow/splotchy.
Left - Critical Cure
Middle - Moscow Blueberry
Right - Afghan
Having issues where 2 of 3 of my plants have leaves curling downwards. One plant's leaves are turning a bit more yellow when compared to a healthier dark green plant. When I water, usually no water drains from the mesh pots. Part of the issue? Or a heat or nutrient issue?
Hello.. Hope you are well.. I just looked at ur dairy and tbh it looks like a slight over feed at sum point and ur day temp is a wee bit on the high side.. If possible try to cool down ur environment and give them a complete flush wit plain water @ph6-6.2(this will help break any nasties out) and maybe give a stress reliever like superthrive or an organic version.. Resume like normal after flush out but cut bk a little bit on her food.. Its always easier to add more on nxt feed than to flush out cuz of 2 much.. Stay safe n gud luck with her.. 👍🍀
Day 99 (May 9) - Afghan and Critical both had their leaves "clawing" downward last week. It seems that the consensus is too many nutrients, probably too much Nitrogen, which plants require less of during flowering. I flushed the plants beginning on May 10 with tap water (pH 6.5 ish) and used no nutes the rest of the week because nute burn got out of hand throughout this week (see next weeks photos).
I read on growweedeasy.com "If you're looking for a more relaxed effect, I recommend starting the flush when just about all the trichomes have already turned cloudy." Mine definitely are mainly clear, so I'm going to check on them next week again.
My Critical Cure plant has the issues in title, plus burnt tips. Only affect parts of the plant(?) the issue is also a bit on the Afghan. People answered Nitrogen excess may cause the curl. But the yellowing looks like lack of Cal/Mag? My Cal Mag has lots of Nitrogen.. though..
Hello.. Hope you are well.. Do not give her anything but ph'd water now.. - no cal/mag either.. Just plain water @6-6.5.. Her leaves are just the outcome of her earlier feed issues.. Stay safe n gud luck.. 👍🍀
Day 106 (May 16)
Starting the week with some pretty bad nute burn that got way worse over the last week. I had been flushing them every two days instead of normal watering. Not sure when to stop flushing?
I am near the harvest window; day 51, out of 55-65. Last week they had reg water only due to nute burn issue. They have about 1/3 milky trichromes but still mainly clear. Should I feed them their food again, or continue flush until harvest? Should I use TDS meter (what to check?)
Okay again the Wide idea is that Flushing really does something.. Read this. https://www.rxgreentechnologies.com/rxgt_trials/flushing-trial/... Okay Ideally we would not want that type of saturation in Cannabis at all because plants are biologically programmed not to move nitrogen around like People think it would..
Hey :-) Look with a microscope 👌If the trichome heads are about 70% milky and 30% clear, you can start with the flush. If the trichomes are about 70% milky and 30% amber, it is a very good time to harvest 👍🙏🏻 but do not pay attention to the leaves of the trichomes on the buds 👍
Hi!
I think it's best to just keep on giving water only or if you have somekind of flushing/ final solution you can add that ofc.
The time of harvest is coming and my first girls took almost 2weeks from 70% clear to being 70%Cloudy and rest amber.
If you want to use tds meter you can flush with some runoff and measure the tds of that runoff to see how much nutrients is in the soil still. The bigger the difference the more there is nutes left.
Optimal situation would be that all of the nutes have been flushed or used by the plant before the harvest and the girls start to use the nutes stored in the leaves to get better taste ans smoke
Growers have said my plants are burnt/curling due to nute burn, but I noticed that they are only particularly bad on the upper leaves and the sides of the plants that are more directly under the lamp. Is this light burn? What do I do? Ive been flushing but the burn continues.
Hello buddy.. Hope u are well.. As we av all been trying to resolve with u.. Yes its both.. But a combination of both is why ur middle plants wer effected mostly.. Obviously its a wee bit cooler on the outsides of tent wer air flow is easiest.. But leaves are still burning at tips.. Once problems arise with cannabis it csn b very difficult to resolve these by time of harvest unless in veg stages.. Flowering problems are harder to rectify because she's already on the path to finishing.. If possible on ur mxt grow just b more cautious with heat.. Aim ur fans at slightly upwards bringing fresh cooler air from ur vents up thru ur canopy and another fan on lights to cool them down.. Maybe try to invest in either a big outtake fan or add a slightly smaller intake fan to help keep cooler air directly into room n not thru just being vacuuming by outtake fan.. All other factors seem great n uve just been unlucky tbh.. It happens to us all.. All u gota do now is think howcan u get round this problem n stop it happening again.. Wen all leaf is trimmed off n she in curing she will look alot better.. If u can fix these problems ur yeilds will definitely increase as ur plants will b healthier.. Stay safe n gud luck in future gardens.. 👍🍀
Day 113 of grow (May 23)
Day 56 of flower.
Still flushing. Trimming the main burnt leaves and burnt leaf edges. Not sure if that was helpful or not but was tired of seeing them burnt looking!
Trichromes are still mainly clear. The Trichromes at the tops of some of the Blueberry colas are white, but the rest of the stalk still has mostly clear heads. Hoping they will be ready to harvest soon.
Day 120 (May 30)
Switched their light cycle to 10 hours of light, which supposedly makes the trichromes finish sooner. Much more white trichromes than before but still not there.
Harvested some of the taller Afghan buds, which do seem ready, but they are super hard to trim because they are made up of foxtails which all have their own non frosted leaves surrounding them. They probably foxtailed due to the heat combined with the strong lamp light. They smell very strong, like sour citrus. Unfortuantely the other strains dont smell very much, even when touching them, probably due to being dried and burnt from the heat, low humidity and nutrient burn. Some of the lower buds, away from the light ironically, are actually smelling better on those plants.
