The temp is when lights are running is about 35C. Humidity is about 70 which is abit high but exhaust and intake fan is constantly running aswell as cooltube. Only running one 600w hps til the white widows are put in. Is it a nute problem?

Temps are way to high unless you are running c02 enrichment. That definitely isn't helping. How is your PH?

You sure that is jack herer? Looks pretty indica to me...

As Banditt touched on first, the pH is most likely the problem. High pH will usually cause gnarled and deformed fresh growth.

Ya it's JH alright. Ordered from online. The temps only hit the close to 35C early afternoon and drop to around 30C by nighttime. Havent had this problem before going at those temp's but i was growing a pure indica strain that time round. Dropped my Ph pen in the water a few weeks back so cant test the ph at the moment. I just estimated the usual amount i put in. Might of under-estimated so i'll at a few drops more of the ph down. Doesnt drop below 25C here at night so keeping the temps below 30C is almost impossible exact if u were to run a air-conditioner 24-7.
