The spots look almost like you dripped some nute water on them or something. the yellowing is on a lower leaf so it looks like a ph swing locked out some nitrogen or MG and the intensity of the light faded it a little.
Just read that ph isnt an issue, led's will require more MG and a higher concentration of nutrients. feed it more MG before you put it under the led.
if you look at my pic you can see where the red MG spots on the yellow leaf only showed up RIGHT under my led.
Look hungry to me! Nitrogen starved!
I go whole grows without any run off until final 1 to 2 week flush and feed nearly every watering. These strains nowadays can suck up a lot of nutrients.You're plants are starting to consume themselves! Gotta pack you're plants full of nitrogen till the end of stretch, most of these nutrient formulas sold don't have nearly enough nitrogen. Most people blame their problems on PH, it's not PH, soils and soilless mediums already have buffer in the soil to adjust itself and when you add ph up and down is just to keep from spikes but if it spikes the buffer will adjust it pretty quick. Just add ya some nitrogen dude and don't be skimpy about it and once you start to get their nutrients back on track, it's not going to be an over night fix, their going to keep consuming themselves for a few more days until they get replenished, so feed the shit out if them and don't expect to see any fix for about a week. Flushing the medium at that stage of the game is about the worse thing you can do.
These are leafs on a plant that is in final flush and starting to consume itself from not enough nutrients.
Hey took a bit to get a better pic.Can you get a close up of the underside of the large dark patch. Looks strange to me. Plants look slightly yellow and could probably use some N and calcium but the dark spot looks odd.
It’s not the same leaf I think.Looks like it. A handful of garden gypsum will help. Was looking like phos with that dark patch before but looks much more like it is in need of calcium now. Is that the same leaf?
