So this is my 5th or so grow and prob my last if I mess it up.. Again.. Ive always seemed to over water.. And then get lock out and just end up with buds that look bad and don't smell great.. I'm using 5gal air pots with palgron light mix soil... My question is how much do I water a seedling... When should I give them there first big watering and how much??.. To run off? Just before run off??.. And what's the best ph I know between 6-7 but some say 6.2 some say 6.8?
