im checking ph by the runoff. im using ro water..not sure if this is alkaline.
Would it be ok to flush with a ph of about 7.1? would this bring up the soil ph?

no...whenever it needs water...about every 3 or 4 days.
im using ro water so i figured i was missing calcium and mag so i added cal-mag and they improved...much more green now but some of the lower leaves are still yellowish.
2 weeks into flowering and some middle and lower leaves are turning yellow and have brown spots.
