Hey Stoners 
A problem came up today only with my "Candy Kush" girls, they are on day 19, in Biobizz AllMix soil, started feeding them "water + BioGrow 1ml/L" only, under 600w hps.
The problem is that the lowest 2 leafs are curling, twisting and color changing, and on the second node the leaf tips are having this yellow/brown colors.
Is a an early sign of Ca/Mg deficiency? or you think it is another issue?
