Yes but when you fed your plants the one time you mixed it at 1.2 ec from memory and I said to bring it down to 0.8-1.0ec for those. My reason was becuase the tap water will have som ereading but I think you used RO water from memory, correct me if im wrong.
A plant that size only needs 0.8 -1.0 ec above the water reading before adding nutes. And the ph I would set at 5.8-6.2 to start with.
Once they start their rapid growth they will require watering more often, and that will adjust your ph when allowing some run off.
They should be good if left to dry out and grow. If you must love them spray with growth enhancing seaweed extract just before lights out, mist so it stays on the leaf and absorbs in their sleep, not till it runs off. Breath CO2 onto them, just dont add any more water.
Did you have a job in Guantanamo doing water boarding rofl.
