S03: Dark Phoenix - Green House Seeds

Autos take less feed than photo period plants. They start feeding at 200 ppm 0.4 ec and work your way up by 100 ppm 0.2 ec every week if your seeing good growth and the limit for most autos would be 600 ppm 1.2 ec in water,soiless, cocoa or peat grows. Go back to 300 or 400 ppm until you see some recover then work your way back to 600 ppm the way I explained.

With your PPM's that high and rising I would say you are over feeding her and what you are seeing is nutrient burn. You want your PPM's to stay stable. If they are rising then your feed is to high and you need to dilute your water. Looks like you recently lowered your humidity from 50% to 30%. When you do this you are causing the plant to transpire more which means she will drink more and by drinking more she is up taking more nutrients. PPM levels should be adjusted to take this into consideration. Plus the huge defoliation would also cause a need for less food as there are less leaves to grow. You said last week you were going to do a water change. Did you do this? when flowering its best to do a water change once a week. Happy growing
