Its week 3 into flowering and one of my hydro plants looks to be going downhill. Its an Ebb and Flow that floods 2 times a day for 15 min. The plants are in rockwool. Temps are fine and so is RH. PPM is around 1400
its a watering issue for sure man. Make sure your ebb & flow is getting to that one like the rest.
I forgot to water one of my plants for a few days and it looked pretty similar. Id say its a lack of water but over watering looks about the same
Floods at 12 noon and again at 10pm (basically an hour before and after dark cycle. It floods for 15min at a time. Since its rockwool I dont think its underwatering, but overwatering maybe??? Should I go 1 flooding a day or should I go from 15 to 10 or 5?
