Royal Seed Critical Hydro First Grow

Day 22- the plants appear to be doing good and reviving. Plant 1 &3 has some dry dead leaves that I will probably just cut off today. Plant 2 seems healthy and happy no sign of dry/damaged issues yet. Water pump on 2 repaired and back on. Some pics of each plant in grow light and camera flash as well as some pics of leaf burn. Stay tuned. Day 23- trimmed some of the dry/dead leaves from plant 1. Plant 1 might be stunted we will see. Play 2 is perfect and plant 3 does have some damaged leaves but I left them because they aren’t dry yet and could be repairing the plant from my wrath. Some closeups today of 2 & 3 just for the hell of it. Recreational marijuana use is now legal as of today. Enjoy Day 24- plant two still looks really good. Plants 1 & 3 are worrying me. More dried leaves and I’m trying to troubleshoot. It’s hydro so it’s not under watering, light is now 30inches above top of plant and I dropped nute levels. Only other thing I can think of is humidity. I don’t have a humidity tester since this is one of my first grows. The others didn’t grow well or were disturbed. I took the continuous flow tube from top and pointed it to the roots so well see if this helps. Day 25- still seeing more slight spread of burn on the leaves. Moved the light up another 6 inches. I also places a fan on the 3 plants to help push the air along. Plant 2 is still doing wonderful. Well see what tomorrow brings. Day 26-officially worried about 1&3 with the spots. Looks like the dryness of the leaves is not just on the bottom original leaves like I hoped. At this point it has to be humidity that is causing the curling. Everything else seems ok. I cut the dead leaves off if they have more than half damage.
