I began my project from seed and transplanted to one gallon then into 5 gallon and on in a 15 gallon side last transplant 2 weeks ago trouble seems plants don't dry out keep registering wet zone at its core. But also plant is growing every day and each pot shows roots at their bottoms. Pots are also heavy feel to lifting. Some leaf show slight tip curl claw nail but only a few on two sativa the others are indicated and show no concern other that heavy and registering wet after 6 days since last water. I water from their bottoms and flush from their top. Any response on what I'm experience or common knowledge on what I ought to be looking st is appreciated. Hope thus read makes some sense.
