My good friend who I've spoken of before on here is having issues. He's got two plants in flower right now, and the leaves on both plants are very light green, almost lime colored. The bottom leaves are turning yellow, and then getting grey spots on them and are dying. He thought the issue was nutes, and two days ago added some Tiger Bloom in 1/4 strength concentration. Today when I stopped by for a morning bong session, the plants don't look much better. The only difference I saw since two days ago is that the leaves seem to have flipped up? If you can understand what I mean.... the leaves usually have a seam in the middle of the leaf, and then bent down. Now they are flipped up...... any help would be appreciated by both of us!!
