Thank you for the input. Ya I figured this would cost me about a week of growth and bud development to repair the leaves.Trim the leaves.. some of the more damaged ones you may even notice pluck off with an incredibly light tug. The plant is going to use energy trying to restore those leaves that it could be using on new vegetation and bud formation.
Hey thanks for the insight. Ive got the light raised about 10" offthe tops of the plants. There seems to be some green regrowth on the tops that got bleached. My plan is to increase the N in my nute schedule for a week or two to help the plants grow new leavesIts hard to tell from those pics, but it looks like the tops were the most affected by the light intensity. I don't think it is a complete loss though. Until the plant is laying dead and wilted and the root ball has shriveled up, I'd say there's always hope.. though setbacks will generally affect your harvest yield. I've never experienced light bleaching on the scale you have here, but when I was using LED's to flower I did get a little bit. I just trimmed the affected leaves off, adjusted the light height, and let it continue.. If I had plants like yours, and if those issues and all of my plants were affected I would probably attempt to top them and reveg. In your case it seems like space may be an issue as it is, so a reveg would turn your cab into quite the cluster fuck without some incredibly aggressive trimming.
All in all, I guess you could say "I'm not exactly sure and I don't want to steer you wrong."
Question for you tendran. I was just comparing my pics from 4/16 to the pics I took today, 4/21. And in the pics from 4/16, it looks like only the tops got bleached.Deeefinitely salvagable! Tons of healthy green on the lower portion.. and it's not as crowded as I thought in there. Didn't realize you had so much vertical height left to work with. One thing to note, is next time you may want to use even less of that height though and do a low profile scrog or sog grow (from clones, preferably, as they'll be bigger and juicier in less time). The LED's DO work in flowering to an extent, but you've got a lot of growth far below the main colas that are going to put out a bunch of wispy popcorn buds that won't amount to any significant yield. 6-12" is as far as I'd ever recommend moving an LED away from the plant.. and that depends mostly on the light intensity (as you discovered the hard way, unfortunately).
thanks for commenting back tendran. here's pics of the labels from the pot of gold, so you can hear it from the horses mouth.I'm afraid I couldn't answer that with any solid knowledge. I've only seen minor light bleaching issues myself, I'm not an expert on the subject.. But the tops of the plants are looking better. I suppose there could be some sort of residual change if new growth is leeching energy from the lower growth (only a theory), but then I would assume that the lower growth would show signs of deficiency and dying off, not so much light bleaching. Are you positive all this damage IS light bleaching? What was that Pot o' Gold stuff supposed to help with exactly? Are you supplementing your regular feeding schedules with that? Depending what is in it, it could be creating an overabundance of certain nutrients causing some sort of lockout? I've never witnessed lockout, to my knowledge, so what would happen if the top growth was being told "repair repair repair!" and lockout occurred through the root system.. would it then draw upon resources in the lower green growth?
Perhaps someone else can elaborate further.
Roots looked fine when I transplated to the new dwc box. Not slimy or even stained for that matter.what do your roots look like? Root rot will make your plants look light bleached and nute burnt. Seen it myself, last 2 grows.
