 leaves turning yellow | |
I have 3 plants in 10th week of growing under 8 2' mv flourescent bulbs - four cool glow and four plants bulbs that I picked up from Home Depot. One of the plants is starting to turn yellow. The bottom leaves are turning yellow first. The yellowing started at the tips of the leaves (i think), and the veins are also yellow. It looks like a nitrogen deficiency, but this is my first grow, so i don't really know. |
