Dude you sound like me on me first grow. Always fretting about something. Seemed like I was in a constant crisis mode. First it was a germination problem - took 7 beans to get 2 plants 17 days apart. It took me until the older plants was 45 days before I kind of figured out the feed/watering, getting the pH and lighting right. Constantly worrying about rH, temps and why they weren't growing. They were about 7" & 6" at this point. Then I got something right and they took off. Then it became a constant battle to keep them out of the lights. Lots of kinked branches doing LST and the grow seemed to go on forever - 110 days from the first sprout. Plants ended up being 39" & 44" with a combined dry yield of 4.75oz. Good buzz but the taste is not so much. Crappy cure. Bottom line is you're going to make mistakes - we all did/do. The key is to learn from your mistakes so you can make different mistakes on the next grow. lolol
I'm gonna pull up a chair for the ride if ya don't mind. Don't think i'll be much help as I know zip point nada about soilless growing. But I'll send some moral support, comic relief, and some good grow karma your way. Besides I see
