Hi there, I’m noticing some of my leaves turning yellow with brown tips. I believe one of the problems was under feeding. Plants are 3 weeks old from planting. First five days only water. Next week and a half 200ppm 6.1/6.4ph. Started noticing the leaves so I up the nutrients to 300 ppm one feeding and then 550 ppm 6.0-6.2 one feeding 2 days ago. Been keeping an eye on them and don’t seemed to get better maybe I should wait more. Was feeding every 3 days to runoff. Is this a deficiency? Can my light be the problem? Also stems are turning red
Lights: mars hydro tsl 2000w(300watts) had them at 28in and moved to 26 two days ago.
Humidity temp: 77f 65%
