The forge (gnome automatics)

My "go-to reference" is this article on defoliation - tells you how, why, when - excellent resource! But as you noted, you need to do this slowly because doing too much all at once will stress and stunt the plant. https://www.growweedeasy.com/nebulas-super-simple-3-step-defoliation-tutorial You've also got some nute problems in your grow ... definite nute burn (far too much nitrogen) and the beginnings of a calcium deficiency because of it. I would suggest nothing but plain pH'd water for the next week and find some bloom nutes rather than grow nutes to start giving her after the week of water... You might also consider using some Langbeinite 0-0-22 - I sprinkle a tablespoon of it on my soil once a month and it's brilliant at helping avoid that kind of deficiency. Good luck!

Well, you've done a lot of lollipopping - but that's about it. I wouldn't actually say you've done a lot of defoliation but I haven't gone back in your diaries to see what she was.... I hope you read that article I suggested before - that should tell you what to do for her. But besides that, there are three things that are going a little wrong here that I want to point out.... one is the temperature as Mazgoth rightly pointed out - that temperature is going to cook your plants. The other is that I'm seeing either a bad pH problem or a hunger issue... I'm talking about the yellow leaf tips. To figure out which, you need to water your plants until there's about 10-20% runoff and check the pH of that runoff.... I would, in any event, get the pH down to 6.0-6.4 max... You don't tell us what you've been feeding them so I can't comment on whether they're hungry - but a PK booster would not go amiss. Finally, I see you seem to have a fairly decent population of fungus gnats (on the yellow stickies) ... Just had someone whose plant had to be pitched because the fungus gnats ate all the roots and caused the plant to become mush.... Now, that was an extreme result of fungus gnats - they usually just eat the decaying material in the soil, but if that runs out, they start in on the roots. So get yourself some Mosquito Bits and follow the directions... they work a treat on fungus gnats. Fungus gnats, btw, like wet soil... so if you have a problem with them, it's because you're keeping the soil too wet... always let the soil dry out completely before giving them something more... Good luck!
