Hello guys. I just plant few flowers from clones in mapito(and coco roughly 10%) , and few flowers in soil. I washed mapito before properly and before to plant i had 5.8 ph and 0.8 ec. In soil they are beautiful , but in mapito no progress at all, cupping the leaves and dark green leaves , i checked again ec and now after 3 weeks is 5.69 ph and 1.08 ec. And i see some green algae on mapito.and to be honest i had low humidity like (45-50) Please help!
