I have my 2 in. seedlings under a 900 watt at 44 in. per light specs. Im getting a light green discolaration on my leaves. any idea’s? Too close?
First welcome to the community. A picture would help a lot towards seeing what’s going on.
Are you misting your plants under the light? It appears it may be damage from water droplets collecting on the leaves, and the droplets act as little magnifying glasses which intensify the light and burn the leaves a bit.
If this is the case, then stop misting under the light. Your plants should then grow out and be okay without further action.
