KushGANGanswered grow question 3 years ago Hello in my opinion you have nitrogen deficience because your plant is too pale after if you have calmag deficience it can be due to excess of potassium and you ph which is not good. Measure the ph of the drain when you water your plant. To correct calmag deficience use epsom salt which is good against this. Hope your plant will recover soon. Good luck
