Hello everyone! I am new here and want to say thanks in advance for helping me out. We recently got mmj in our state and am growing! I have a tangie clone that I picked up and has been great untill I noticed the curling leaves. 3gal pot, ocean forest w perlite, run off ph at 6.5. I use ro water with cal mag set to about 200ish ppm. I usually go about 2-3 days in between watering. Under led lighting so temps are favorable. Humidity seems to be my issue 40-45%, so I hang wet towels to help raise it up. Take a look at the pics and let me know. Second pic is of the complete tent so you can see the setup. Thanks!!!
