Legalized grow attempt #1

First day of week 6. New high volume air pump and air stones are making the girls happy. Some of the mains are messed up from my attempt at lst. Lesson learned. My TDS meter showed up today. My tap water was 20ppm so I definitely need some Cal mag. likely causing my purple stems. Mixed the nutrients at half strength again and it came out to 800ppm. Also Plucked some fan leaves today. Day 40 update. D2 is growing much faster than D1. It's also shown less sign of stress when I was fighting with my temps and humidity. I'm hoping it'll be the better producer and I'll select clones from D2 to continue my grow after my first 2 cycles to compare. Plants have been topped twice so far but I've learned that cutting the mains off when the new growth is so immature isn't the best idea. First issue is damaging the new growth sites inadvertantly. A tiny scrape on a baby growth tip resulted in half of a fan leave fan being damaged. The second issue is the mains are too short to bend over until they grow out more so you're really slowing down the root growth and slowing the plants ability to recover. pH has been pretty stable since the res change at about 5.8. Ppm is steady as well after the res change. Immediately after the res change the ppm was at 800. The next morning it was roughly 670 and has stayed there every since. My Little plants haven't drank enough to top up the res yet. With a 7gal volume I'm guessing maybe a gallon/week which is about an inch in water depth. The plant growth rate is amazing me. I left it for 30hrs this week and it blew my mind how much of a difference I can see. For a first time grow, this is much more than I expected at this point. I figured I'd have used up all 5 seeds trying to even get one past the seedling stage The bad side is I have an obsessive personality and can't stop looking at the photos I take 😂
