PH Balance for hydrp & soil----Leaf deficiency chart

Your leaf damage may be from improper pH range, heat stress or a cannabis virus, the leaf damage indicates either a pH disruption, heat stress or a cannabis virus. If it is a cannabis virus I believe most of your plants should be displaying the same leaf damage and the plants would be in much worse condition. I believe the leaf damage on your plants is either from heat stress or pH imbalance and would make your last step before watering your plants checking the nutrient mixtures pH and adjusting as necessary.

I would remove the damaged leaves so you may track any further leaf damage and to your plant to make diagnosis more easy.

You want pH 5.8 for hydroponic and soiless (peat moss and coco coir) and pH 6.5 for soil.
