White Widow clawing

White widow clawing during flowring, been in flwr 1month, ph 6.1, nutes 900ppm, temps 70's, water temps 17-19celcius, 12/12 400watt hps

whats your humidity?

Too humid or overwatering... It happens to me all the time... Its even in my journal...I am growing white widow too.... Don't be too stressed about it... My plant claws like that too... Its not going to affect your harvest... Sometimes the plants just do that... Are all your leaves clawing??? If not, then don't worry too much... Back off on watering and see how it goes... If you are really worried, flush with low pH water and nothing else for two days..

humidity?? dunno my wallyworld thermo/hidity meter has always shows 20%, temp works fine on it but yeah. I had actually backed off watering's few days before posting and it seems to be progessing with the MBK's flower wise so hopefully you're right lacey, thanks for all replies.

sorry for ignorance but what is clawing? never heard term

Uhh put ur hand out in front of you palm down finger sprawled out, now allow ur fingers to curl down and thats what they look like
