All during few weeks of vegetation fed the plants same tap w/PH 6.5 aim as in thought of watering plant from first w/correct PH ought to prevent soil issues. Up until this last week of vegetation both Panama and Critical Mass yellowed up and curled up within this week. Same problem as last batch w/yellow/brown leaf. Last batch figured too high PH until figuring out how to keep tap around 6.5 aim caused the soil unbalanced. Yet these two have had perfect PH the whole growth and now starting to show leaf damage. This time immediately flushed w/distilled. Last time added raw potassium to watering since curled/brown supposedly lack of pot. Going to see results of flush or until I figured what the cause is if isn't a matter of PH balance.
