Anyone know what the problem could be here? They are all in coco coir, same size 9L pots. All are clones of the same plant and get the same amount of nutrients. Currently using gh micro and bloom and extra calmag, but I'm about to run out so next time they'll be fed floranova bloom. 20ml micro, 30ml bloom and 10ml calmag on 20 litres of water. Ph is 5.8, give or take .1, every watering.
