Spring grow, four strain

Little white hairs appeared on cheese and purplematic over the weekend. I feel its a bit early for purplematic to be starting flower, especially as its still very small, but the temperature outside has been all over the place, from heatwave to snow, then the heater kicks in and drys the air out. Cheese is doing very well though, just a small amount of nute burn on the top new leaves. But lots of potential bud sites. Gorilla and euphoria are getting nice and bushy, lots of potential bud sites, but the light isn't hitting them well, so will apply more LST.
