I posted this earlier but the thread seems to have disappeared.
I'm a newbie and I'm not sure what's going on here. See photos below.
This is a Wedding Crasher (hybrid) clone, transplanted 2 weeks ago, in early vegetative stage, grown indoors in Fox Farms Ocean Forest soil. No nutes added (except I added SuperThrive after transplanting, and top dressed with a little kelp meal a week ago). Soil pH has been around 7.0-7.2 (until being lowered today). Had some very high heat this past week, and temps reached 85F a couple days and I think I had my LED light to close to the plants because I did have some upper leaves taco. The plant has always been kind of spindly, but growing fast.
This problem is on the older, lower fan leaves. They are developing small brown spots near the edges, and are starting to turn lighter green, starting at the edges. I'm also seeing edges lightening without brown spots (as in 3rd photo). New growth seems unaffected.
My immediate thought is calcium deficiency, but this is good soil and the plant has been in it only 2 weeks, so the nutes couldn't have been depleted so quickly. I also have other clones planted at the same time, in the same soil, and none of them are showing this problem. Just this one plant.
Can anyone tell me with a reasonable degree of certainty what's going on here, and how to fix it?
