absolutely need to do a strict wet dry cycle especially at the seedling stage. for seedlings you do need that cycle but make sure you don t over do it and leave them too dry too long, they hate that more than too moist. For seedlings and autos, VPD is very important : the vapor pressure deficit. VPD regulates the metabolism of the plant and the metabolism is the difference between an optimal grow and a slow grow. learn more here http://www.just4growers.com/stream/temperature-humidity-and-c02/vapor-pressure-deficit-the-hidden-force-on-your-plants.aspx ... try reducing your PH to 6 (what s the PH of rain water bro ?), and put a plastic see through cup on top of the seedlings to get that humidity right. spray with cal mag and kelp extract until dripping twice or three times and week and see for yourself ! hope this helps ! :rocket:

Yes wet dry cycle essential...if theyre wet all the time they'll drown like mine did...if they're dry all the time theyll likely die also. Dont abandon the stuff you already know because of being autos...i tried switching my usual ways and woohoo did i pay the price.

Yes, do a wet / dry cycle. It will force the plant to develop a healthy root zone. The problem you are having is because the plant is in a pot too big for its size; it should have been placed in a solo cup at this stage. Once the plant has populated the pot with roots you can use the auto por safely.
