Looking back at your diary I noticed you've increased your nutrients quite a bit according to your logs, do you verify your ECs/PPMs? To me it looks like a combination on nutrient burn and proximity to your lights. Running a 400W HID at 11" to your light I'm assuming your using are Air-cooled system? I'd move your lights slightly up and back off your nutrients to the levels before the tips started to burn. Hope this helps but you are in the final phase of your grow and now less is more as your buds are formed and you are preparing for your flush. You won't get bigger buds at this point no matter how much nutrients you give or the output of your light. You actually want to be on the safe side and preserve your buds and the trichromes. I've seen worse so nothing to panic about, cheers.

A bunch of different leaf symptoms appeared over just a few hours, can you spot the issue in my detailed diaries and solve the mystery?Everything was well, until over just a few hours they developed all kinds of symptoms.
I have 2 diaries here for the grow, the 2 called “Grow #2” and I am very detailed about what has been done day to day.
So please have a look and see if you know what might be happening

Can anyone help identify this tox/deficiency?Week 6 I noticed that all the new growth has burnt tips I assumed this was a bit of a nitrogen toxicity problem since the leaves were all a nice dark green, no pale leaves were popping up. Also held back on feeds for a few weeks. Other forums said it’s normal but want to be sure.

Передозировка или свет?Подскажите правильно ли я идентифицировал передозировку удобрениями. Не думал, что органические удобрения могут так навредить быстро растению. Света даю им 550м/моль/см2. Но вот решил дать полторы дозы удобрений, так как заметил легкое осветление листы в середине куста.Week 8

Yellowing/brown tips of top leaves. Heat-burn, light-burn or both?Top leaf tips turned yellowish, brown with curling. I'm leaning towards light burn as the cause, but noticed it started occurring during the recent hot weather. I've raised the lights, but am wondering if this could actually be related to the heat.

How to tell from light burn vs nute burn?Some of the tips of my leaves are turning yellow/white. This is only on the top leaves. I would guess this is from light burning the leaves and not nute burn since all of the lower leaves are not showing anything like it.

Harvest Time?2Stunted Autoflowers
Top Cola seems ready, though lower bud sites are still underdeveloped.
Seems there's lots of amber, though maybe still cloudy.
Should I wait until the lower buds develop and risk degraded THC, or harvest now?
Any help would be great, Thanks
