nft hydro help plllllls

[moarihacker]

Theres some thing wrong with my plants they are twisting at the tips very brittle my temps are at 65 F ph is at 6 feeding is at 500ppm or 10 ,3 weeks into veg. The lights are at the right height just cant seem to get it right some hell. So pls if some ones got an ideal pls help me out. Could this be heat stress or nutrient or could it be the fan blowing over them i have heaps of fresh in coming in and extraction fan blowing out.

If its hydro pH is a little high. Shoot for 5.5-5.8.

Cheers ive changed it to 5.7 -5.8 just crossing me fingers that ill pull through it sucks not knowing weather or not they'll survive or not . I ll keep you updated hopefully it will work for me.

I would think they would be ok. They look fine with plenty of green leaves on it still.

Yeah cheers for that so far they are still alive and kicking added some superthrieve to see if that works for them. i will update pics if they start to pick up. Changed the res water added a little nutrient and made sure that the ph was around 5.6. Now toes and fingers crossed.
