First Grow- BF Laughing Buddha, RQS Dance World, BF Shiskaberry, RQS White Widow, RQS O.G. Kush

The first three girls (Shiskaberry, Dance World, Laughing Buddha) are looking healthy and already growing more stems after topping them last week. The back three girls (O.G. Kush Shiskaberry, White Widow) are stretching up and growing its first sets of leaves. At the end of week 3 some of the girls started showing some brown spots and some browning on the leaves. After asking a grow question, I think the culprit might be my misting them under an led and possible ph balance issues. Some people also suggested it might be calcium defiency. We have very hard water with lots of calcium so I think adjusting the ph might help, next watering I am going to ph it to 6.3 to test it out.
