<edit> The burnt margins suggest nute burn, some sort of lockout. Too much P?

thanks cannabineer!!!

i say potassium deficiency.



MJ loves potassium more than any other nute!

but mine are not clawing down their the one in your pic is

3 more (2 days newer) pics of the sick fan leaves.....and a pic of one of my 3 main colas just for good measure...almost 4weeks

K def good call imo ... sometimes get leaf/edge necrosis with that. You seem to have plenty of N.
cheers 'neer

<edit> looking at that young cola, I see no signs of Mg deficiency. You're running generous P, so K could be it.

im new at this but maybe in advanced sulfur or zinc deficiency?

for real? i just found it myself like a week ago! fuck man...anyway, it helped me recognize my deficiency of nitrogen and phosphorous...idk if it was correct or not but increased nutes and problem went away...it was also enough evidence to convince my buddy that it was deficient and not overferted like he thought

there is no magic chart out there...you really just have to narrow it down yourself

I seem to find that so long as your using a balanced and complete nutrient regime. The main issue is always over and under fert.

I try to keep my plants on a minimal p and k diet until as far as possible into flower (usually bumping it up beginning week 5 or so) because too much and it just locks out. If you have been feeding them that much and there hasnt been enough run through this could be the case.

I think cannabineers first edit is most likely correct. I would water through with plain water for a bit give them a proper soaking (lower the ec of the pots contents) and see if they start to look better you should notice fairly quickly they will just sharpen up a little bit.

I had a similar issue where I drove myself crazy trying to fix the def and in actual fact it was just build up and a good flush and keeping them fairly wet until the nutrients leached out helped them bounce back.

This is just what I would do and please bear in mind its just the stoned ramblings of a guy who likes to grow pot

Grow room? Or outdoor? looks like slug, snail or caterpillar damage, and cold wet plants

edit: don't bitch at me just my first thoughts
