GrowerOGanswered grow question 2 months ago Hello mate, these signs seem a problem that comes out with a not perfect balance of the Ca/Mg rate in you water, these two nutrient are like macro-nutrient but it works well when they are in a rate of 3/1 or 4/1 with the organic feeding. Looking your plant in the diary i see also the upper part of it, the plants are showing the tipical discoloration of this condition. You should do a total flush and then re-feed whit the rigth rate and all will be fine.
Good luck and happy journey!
