whats happening to this plant??

what is happening to this plant?

its growing in a hydroponics tent with 6 other plants, the breed is purple widow,

there growing under a 250 w halide light,

whats can be the problem please help?

THats nut burn all the way. Flush with diluted fert and then clean your reservoir then try again with a lower nut solution.

well your using a 250watter, you need good ventillation, lot of fans for a light like that...Maybe its heat stress or nute burn....are you using nutes???? what the temps....????

If it is not nute burn, try moving it out of the grow tent...I had a hydrofarm habitat that killed several plants, which was a known grow tent problem.......they turned yellow, then brown, then crinkled up, then died......also, when they were seedlings they were light, light green, which is not how the strain started out in other, non-tent grow. I tore that fucking hut down and hauled it to the dump....300 dollar trash!

thanks for the replys guys, i havnt used nuts yet, the light is 2 foot from the top of the plants, and every vent hole on the tent is open, the temp is around 70-80, i havnt a clue why there doing it?
its relli weird.

probly too much nutrients in the soil......fuck....i don no

Looks like nute burn to me. What kind of soil are you using

i dont think it can be nutes tho bcus im using BIOBIZZ soil imported from amsterdam, and im not using nutes, man its confusing the hell outta me

flood the pot with ph 6.8 water then test the water runoff. It could be in the soil.
