Check the PH on your runoff. Looks like she might be having a nutrient lockout. If the pH is fine try supplementing some cal mag in. 🤘😤

Plant starting to yellow too fast The crystal meth has started going yellow very fast. The buds still have at least 2 weeks of growth needed to fatten out and pack the trichomes with thc.. I know it is normal to start dying but isn't this a bit early? Should I let her keep going as long as sugar leaves are alive?

Nitrogen deficiency or could it be nothing In the pictures you see some yellowing and small spots. I don't know if it's Nitrogen deficiency or not because it stays with those two leafs.

I have lots of yellowing on the lower leaves of one plant. After reaserching I think it’s a nitrogen deficiency. Also today I’ve noticed lots of teeny tiny white/clear bugs! I’m super anxious about it, thinking my plants are goners. Any idea on what they are?

Leaves yellowing and burning mid flower Air exchange, pH, nutes, and water should be good. Could my 230 watt on 100% be too much for her? Does she need more humidity? What causes crispy leaves?

Sugar Leaves Turning Yellow Sugar leaves around top colas have started to turn yellow? No yellowing on any fan leaves. Plants are same distance to light and the environment has stayed constant. Only changed feeding cycle from alternating feeding/watering to feeding,feeding,watering (ppm still the same).
