Here is my advice. Shelve the soil and nutes you have. Buy a bag of fox farm ocean forest and some seedling mix - sunshine mix 4. And use that. It is just so easy. What strain are you working with again? Get something that is easy to grow this time - just about any kush, big bang, lemon skunk, something that will be forgiving. That was the key to my first successful runs b/c god knows those poor plants never should have survived let alone produce significant product! Perhaps you have good chemistry skill but otherwise, hydro is going to piss you off. Screw it up at any point and you will end up with a bucket of slimy roots. If you go hydro do lots of reading! Keep with it. It just takes a bit of perseverance.
