    These are Girl Scouts and I am using RO water to mix my solution. I even added some MagiCal.

  2. It's weird because the leaves are yellowing which means there is a deficiency but the tips are browning like its burnt. Right now I have them under two T5 HO 4000 lumens bulbs. It's been three weeks under these lights. I have a HPS 150 hood too which I plan to use for flowering, should I switch to that light now as it could be a light intensity issue as well, right? Master growers I need your wisdom! I come humbled and ready to learn!
