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.

Brown spotsHello everyone,
I have to ask the same question, since that problem is spreading although I give her CalMag.
9 days ago only 2 fan leaves had those brown spots, now almost all of them are affected, especially higher ones.
I wanted to feed her once again and then start flushing

leaf turn pale green and fall offCurrently at day 42. A couple of weeks into flower.
While all looking nice and bushy I did notice severe discolor and some of the leaf just snapping down.
At first, I thought it was Cal Def. I did follow up with the next watering. However :( what did I do wrong here? Cheers.

Edges of sugar leaves on top cola brownFor two of my plants, the edges of the top colas' sugar leaves have gained some brown color. It showed up shortly after I introduced the grow light on full intensity which leads me to believe it MAY be light burn. I'm also paranoid about bud rot though. See photos. Your thoughts?

Orange/Rust Spots on LeavesI keep getting these spots developing on my oldest mother, the MAC. She's probably rootbound, it's been about 4 months since she potted up. I need to keep her in a cup for space, will deficiency get better if I just trim about 50% roots and plant back in a cup with fresh soil?
