Some about my setup is in my signature. RO water PH 6.0 w GH Cal Mag and GH Flora Trio, early growth every other watering/feeding. Water as needed when pots are dry. Usually about 8 oz each every other day of either nutes or plain RO w/ Fish Sh!t @ 5/mL per gallon. Currently in FF Light Warrior soil will transfer to Roots Organic 707 if they make it that far. Calibrate my pen weekly. Checked it against the colored drops to make sure. I’ve had five successful grows in this setup.What about your setup ?
PH levels ?
type of soil ?
watering practices? How much and how often?
nutrients ? Any kind ? If, how much then ?
Using cal mag supplement?
