so there was a bit of yellowing on the initial baby leaves that popped, but I assume that was because I wasn't PHing properly. Other then that I'm really happy with how they look right now! still under 24 hr light cheap CFLs looking to upgrade to better CFLS or an LED for deeper in veg stage and start going with the 18hr light soon but for now just working with what I got! I'll leave it on 24hrs for now until I get better lights. Also introduced them to nutrients finally and they're loving it ! Flora trio series and Calmag FTW right now!
