7th grow, 2nd time growing Stress Killer, 1st time using Grow Diaries.
I know some people don't like using plugs with autoflowering plants but i am currently flushing another plant so the pot is still in use.
Started the seed germinating on 30/04/2020 and transferred to a coco plug on 3/05/2020.
Placed the plug into my tent under a cover to maintain humidity levels.
I have removed my home made propagator and the leaves are starting to develop nicely. Plant looks healthy so far and doesn't seem to be stressed.
End of the third week and the leaf sets are starting to develop nicely and there have been no issues thus far.
Week three and Stress Killer is looking healthy and growing nicely.
The temperatures were getting a little high so i have added a passive inlet tube from my window. This seems to have dropped the temperature nicely. If the hot weather continues i will start freezing a bottle and put it in the tube.
Stress Killer is growing nicely and i have started to do some LST by bending the main stem over to reduce apical dominance and to stop it getting too tall in my tent.
As we enter week 6 growth looks ok. I started LST last week. On thing i did notice on my previous grow of SK was that it did not grow very large after LST began. I meant to hold off stress training on this plant to see if that made any difference. I will have to remember to do it on the next one.
Weather got a lot wetter this week so the humidity has risen considerably.
Stress Killer has definitely entered the transition stage and has had quite a growth spurt. I have continued to do a little LST but not a huge amount. It is already bigger than the last SK i grew, which is a very good sign.
Two strips of the blue LED's went on my light. I contacted the supplier and they are sending out some replacement parts so i can fix it. It shouldn't be too much of an issue as they should have enough light.
Week 8 and stress killer seems to have stopped growing and settled at this height. Now the pistols are starting to develop into buds. I have started to give it some, low dosage, PK13/14 at this stage.
We had a bit of a heat wave on day 53-55, the outside temperature peaked at 31˚C. The tent temp topped out at 29.7˚C.
Stress Killer is looking nice and big. It's gained a decent amount of size in the bast week and seems to be expanding outwards. The first Stress Killer grow i did topped out at around 25cm but yielded 1 ounce of super dense buds. This one is currently twice the size so i'm expecting good things.
Noticed the leaves are yellowing and some are brittle. After asking the community it seems there could be a number of issues (i didn't like to choose just one as the answer as they all seemed like good sensible advice). To start with i have not watered it for three days to let it dry out and i will reduce the nutrient levels to see how it fares. I have ordered a pH meter and a TDS meter so i will be able to monitor those metrics and hopefully get it back to being healthy and vigorous.
Thank you for all of your answers to my question.
Hello all,
I've noticed the leaves are starting to yellow and some are getting quite dry/brittle. Is this a sign of overwatering or perhaps nitrogen deficiency?
It is on the same watering schedule as my other plant which looks healthy but obviously has different genetics.
Привет, друг! 👋
В коко и смесях без почвы не может быть переполива, коко обладает большой пропускной способностью к солям и они просто вымываются из коко с новым поливом, при этом корни всегда дышат и им всегда хватает кислорода (а кислорода мало не бывает!!). Если поливаете в таком возрасте !не больше 10%! от объёма субстрата и даже каждый день - как надо! Собирайте свой дренаж, если его много, выход дренажа измеряйте (если хотите понять сколько она ест) и оставляйте его, она его за час выпьет. Старайтесь вливать в ваш коко воду очень аккуратно, не размывая его, потому как в 2-3 сантиметрах под поверхностью, могут быть большие корни и растение будет подвергаться лишнему стрессу. Сделайте себе капельный полив на основе бака пластикового, с выходом внизу под трубку капельного полива 5-8mm. Расположив бак выше горшка, будет идти подача на ленту полива. Это не дорого сделать самому и очень оправдает в будущем! Растение будет вам благодарно! 👌
Диагноз точно нельзя поставить. У вас в дневнике нет информации какой у вас ppm раствора, какой ph раствора, какой выход в дренаже после полива (полив 10% от объёма субстрата в таком возрасте как у ваша девочка!). Видно что вы его хорошо кормите, в повышении дозы удобрений оно бы не нуждалось точно! 👆
Скорее всего проблема PH! В таком возрасте ей положен 5,8ph в коко и его смесях (без почвы).
У вас хорошая лампа, но возможно она близко к растению, проверьте освещенность в крайних точках роста растения и по его бокам! Bridgelux/Epileds led с хорошим потенциалом.... я бы даже сказал что Bridgelux- то что надо! Epileds- решил kingbo производитель немного сэкономить. 😉
Ты можешь измерить освещенность (lux) в месте культивации над растением!
Установи себе на свой смартфон бесплатное приложение из маркета "luxmeter", протри хорошо телефон со стороны экрана, очисти от жира и загрязнений. В экранной части находится датчик освещенности, который зачастую не уступает индивидуальным lux-метрам. Проверь освещенность над растением. Отрегулируй лампу по высоте, чтоб она и не грела растение до шоковых состояний, но и была в пределах диапазона lux. Установи приложение, ещё не раз меня вспоминать будешь, братан! Оно тебе будет как компас в освещенности! 👌
Диапазоны эффективной освещенности, начиная от посадки растения:
1 день (250-500lux)
2 день (500-1000lux)
3 день (1000-2000lux)
после пяти пары листьев, полная вегетация (2000-20000lux)
Цветение (20000-100000lux). Старайся не задирать выше 99000 lux. Иначе - могут быть проблемы! 👆
И я просмотрел все твои недели. У тебя на 8 неделе роста в фотографии 56-1 наблюдается высокая токсичность азота! после этого у тебя твой самолёт вошел в штопор! смотри что происходит с твоей девочкой! Это всё скорее высокий PH ! Многие гроверы здесь, как я заметил, любят высокий PH и самолёты в штопорах! Я бы рекомендовал снизить на 30% твои добавки. Если в добавках очень мало кальция и магния, тогда внеси добавку cal/mag 1 ml/l (для осмоса), 0.5 ml/l (для водопроводной воды). 👆 PH 5.8
Удачи, друг! ✊😇
After the issues i have been having with the yellowing leaves i bought a pH meter and i am now measuring the pH of the solution i feed to the plants. If it is high i and some 100mM citric acid to bring it down to just below 6. I trimmed the majority of the dead/dying leaves off and the buds still look good.
Stress killer looks a lot happier now that i have been Ph ing my solution before adding it. I have also been using citric acid to bring the pH down to ~6 and i've been letting the coco dry out a bit more between waterings.
SK buds are very dense. I'm quite happy with how it is going, even after the slight hiccup earlier on with the watering and the pH. Still a lot of white pistols on the plant so i think it will be another couple of weeks yet before it's ready.
I attempted to take some trichome pictures by holding my jewellers loupe over my phone camera. The end result is not terrible but also not super clear. From what i can see myself there are very few amber trichomes. I'm going to try and wait until there are a few more before starting the flush.
If anyone has any tips on harvest timing just leave a comment. Deciding when to flush and chop is one of the most difficult bits for me.
Flushing started on day 95. Just using a small amount of Cannazym and some water.
We had a heat wave over the past week and the temperature in the tent topped out at 32˚C. The image above shows what looks like some foxtailing, perhaps due to heat stress (Day 99 - 4).
I started flushing SK on day 94 and i will harvest on day 100. The trichomes are milky and amber and i'm concerned about the foxtailing. Plus it's a good size😀
This was the second time growing Stress Killer and i had 100g wet and 24g dry so this plant was substantially larger.
Generally pretty easy to grow. The only hiccup i had was due to my errors rather than the plant.
It will be a few weeks before i can test this batch but i always found Stress Killer to be a pleasurable smoke. The high was never too intense like some of the super high THC strains as the CBD balances it out nicely.
I have 1 Stress Killer seed left then i think i will have a crack at another ~1:1 THC:CBD strain.
I am very happy with the outcome of this grow. I was not expecting to get 2 oz after the stress it seemed to be under earlier in the grow.
All round pleasurable grow that has produced some seriously fat, dense buds. I look forward to seeing it dried and cured.
