I’ve been growing some indoor for 3 months now and the new growth seems to be having a big problem on just one out of 4 plants. A friend said spray cal-mag on it twice a day for three days but hoping to get a professional opinion incase this isn’t accurate. This is my second year with a more serious approach and learning a lot from you guys! Growing in a 5×5 vivosun tent. 10 gallon smart pots. (I know i should have gone with 5-7g if im doing 4.)with fox farm ocean forest. 1500w bestva full spec. led light. Ac infinity fans…well ill stop rambling and just show you some pictures. Thanks dudes!
