So this perticular plant is only about two weeks since it broke soil.. At first the leaves had some wierd growth patterns but I hoped it would grow out of it. Then the new leaves started comin in normal when the cotyledons and the first single blade leaves started to yellow out and now eventually brown up at the tips. Also this morning I could see the cotyledons are dead and the first set tips are somewhat curling up. I fed it a small feeding of 6.5 ph bal water w calimagic. This is a fem ak48 and The plant is currently in ffof with a mars hydro 300w plus 4 23w cfls till my new cob led comes.. So.. Any thoughts? Is it the mag? And if so is this plant screwed since it's so young? Thanks for the help. Stay lifted everyone!!
