this seems to be my only problem realy need sorting. thnx in advance

Very recently I had a coming issue with my plants called N toxicity, my leaves were very dark green, but my leaves had not yet started to curl down.
I was pointed to this possibility and checked for pictures, and they do resemble a lot to what you have.

I got it cause I added an additive for P which also had the N in it, and also had given regular nutes.
My solution was to simply not give extra nute feed and fed normal water for a couple days.
But what i read form other threads having this issue there is a risc that if you have already given the nutes, and start watering a lot, the problem could increase as the nutes in the pot got used as there could be an increased uptake beacuse of more water available.

From another topic I read that higher temperatures increased N uptake, might be an idea to try and keep that in check (aim for a bit lower). (not 100% on this, might be worth asking feedback from some others)

If im not mistakin thats just the phenotype.. The plant looks pretty good too me and for some reason i feel thats more common in sativas

I kind of agree, it's not that bad. Are you giving it nitrogen? If you are, you might wanna slow down a bit. Overall, things are far from fucked! Good luck.

Looks good from here, don't love them to death

how often are you watering?

Was every one to two days but i avnt waters them in like 4 gnna do it today

it =looks like they may be over-watered
