1st Grow EVER!!! DWC

Learning a lot still making quite a few mistakes. 1. The light was too far away. Using my cousin's lights he got off eBay no brand and noway to tell the wattage. So I started about 34 in for the "so call" 1000 watt and moved it to 24 inches. My cousin also thinks that another light is 400 watts but we have no way of telling. So I started it at 24inches and now moved it to15.5 inches. I lowered the light on day 15 and the plants seem to be responding pretty well. 2. I used Organic Feterizer. The only nutrients I had at my disposal was my cousins "Fox Farms." This week when I change my water I used Maxigrow Instead of the Fox Farm. 3. Started LST training (for the 1st time EVER) on day 18. I have no idea what I'm doing. I just watch a couple of youtube videos. I'M OPENING TO ANY ADVICE
