Nute burn followed by lockout?
MrStinkyanswered grow question 3 years ago
Dont remove the leaves, looks like you are in full on flowering mode it may be that it needs a drop of calmag. The symptoms fit the stage. It will be burning through nutrients now to flower as much as possible, dont forget.

Yes this definitely looks like nutrient lockout from PH issues. It’s causing multiple problems to get to this stage. Unfortunately you are pretty far along for a heavy flush but I would definitely get those nutrients down.
Check run off for PH and PPM. If it’s coming out 1400 plus then you have issues and should flush some but it will risk yield.
Best of luck and happy growing.
Keep PH 6.2 to 6.8 for soil.

Hello fellow growers :D thx a lot
Firstly, is the reason why my plants (especially cookies) are very slightly curling/folding at the ends of the leaves because the LED is too powerful?(Reason to be worried?)
Secondly, should I start adding nutrients? Just 1/4 of Bio-grow for now?5 years ago

Leaf problem and purple stemsHi,
I have a problem with my auto.
I have purple stems and problems with the leaves.
The soil contains organic nutrients and mycos sometimes I add flowering boost from royalqueenseeds so I don't think it is P or K problem.
Is it a nitrogen deficiency ?
Thank you for the answer

Leaves curling upMy plant seems really healthy but some of the leaves are starting to curl in, I was just curious if this is normal or should I be concerned of a deficiency? My light is 24 inches away and a steady 80 degrees. So I highly doubt heat is an issue. Maybe a slight nute deficiency?

Dear experts, could you help me ascertain whether the 4th and 5th picture on my Week4 diary is really heat stress? The only reason I think that is because of that slight cupping/curling of the leaf edges. Might there be other problems that could cause this?Week 4

I'm having some sort of mold issue I think. I cant figure it out I havent seen anything that looked like this. I've Googled leaf symptoms and molds but nothing looks similar enough for me to say that's it for sure. Any help will be greatly appreciated!
