I thought It was a nute problem but my mind is shying away from that because I have not feed those 2 plant within a week ( I have six, the rest are fine) I only feed every week or two since the soil is so rich, I use the 1tsp per gallon which is the "most plants during early growth-600ppm/es1.3 dosage, which I think is low since it is in latter growth, I could be wrong. I am going to get a more accurate reading for the soil and the water PH up today. Thank you
