I doubt very much that a 150 watt LED could produce anywhere near enough heat or light intensity to cause burning of any sort. It does look very much like a major iron deficiency, something that could be quite easily be cured with the application of soluble EDTA iron chelates (pronounced key-lates), somewhere in the 10-15% range. Hope this helps,... Organoman.

I had a similar problem, and it actually still persists. It must be some kind of deficit or lack. Look at my Lemon Shining Silver Haze. first problems started sometime in 6 weeks of vege. I personally think it has to do with iron deficiency. Caused by unbalanced pH, and poor balance of nutrients provided.

She is growing on soil/coco 60/30 and I just watered 3 times with ph 6 water around 0.02-0.04 gal. Do you think it could be too much light

Leaves spotting brown round shapesIdk What to do anymore. I tried flushing the plant that initially had it, and it kept appearing I then fed it again, it kept spreading.
I defoliated all the bad leaves and it started popping up on another plant's leaves.
Why is this happening? How could I end it once and for all?

Sad Bruce BannerWhy is my seedling so pale? It is cold in my grow space in the basement. She has been growing slowly and I figured the recent cold temps are the reason for that. She’s in the same soil mix as her dark green roommates. The pH meter shows a little on the acidic side.

Bug damage?I hope I’m just paranoid but after noticing the bite in my last question stuff like this freaks me out. Could this be damage from a pest or are they just trichs. Been having nightmares about root aphids. (I also have a potas, mag, and sulf deficiency which could contribute)
