Yeah dude I should have my meter today. I am not sure what the ppm should be. What do you think? They are 25 days now and have sets of fives right now. They seem really healthy lookin good but like I said this is my first grow with hydro. The roots are shooting out the bottom of the 5" net pots. The one that is doing the best has a couple of roots hanging about 4" from the bottom of the pot. Is it ok for the roots to hang in the water? When should I be able to tell the sex. I have them on 18/6.

Peace bro!
