It's hard to diagnose a plant by just looking at it especially when you don't know its history. If I had to guess I would say too much potassium and too much direct sunlight. Have you been feeding it something like liquid kelp meal?

If it was heat your leaves would be curling away from the heat sorce, they're not, plants at that age cant get enough light, so I don't think it's the light. If it was my plant I'd be looking at PH or root problems.

Thanks man

If you're having direct sunlight and high temperatures your Leafs will fold up exactly like that. It also looks like you have a nutrient deficiency may be potassium

Your root ball could be getting too hot. It doesn't take very much direct sunlight to cook a root ball.

That's one intoxicated plant!

Nitrogen????

Nitrogen????

Nope. You'd see tips clawing and slowly starting to burn. Here you have burned serrations along fingers, no red petioles, so no P or Mg problems, basically a healthy plant but with burnt edges. And it's mainly the older growth showing it.

I'd also shoot at high K levels.

Yes that might bit it... I for the same along with a better cow mag issues .through long veg ...but I put them in just over 24 hours of darkness before I flip the lights to 12:12 and I feed them potassium in like a pk Booster along with some stuff for flowering sine then it's like stop growing or gone in to some sort of Shock

im going with K def with heat stress I have the same thing just no taco leafs

maybe a salt build up or a ph problem

What is k def I've got a 600hps on 2 plants would that be too much light as the other plan is doing fine and don't won't anything happing to that one

Is your PK Boost a one weeker or all the way through flower?

All the way through.. it was 100ml in 1 litre of water but I mixed the two together I'll up load a file now
