Yellow leaves with brown patches between veins.Any ideas on what this could be? I checked the PH and it is right around 6.5. I did feed them twice last week as I was out of town over the weekend. When I got back the temp in the tent was °91. It's bad on one plant and starting on another. The rest look healthy.

The clone has bad leaves. Need helpTell me, friends, what's wrong with my clone, I still can't figure out what's missing or too much. When I gave him just water PSH 6, ppm 10-15, he turned yellow. When I added water with a minimum amount of fertilizer for 1 week for vegetation, it also turned yellow.

Yellow Leaf Tips with Brown Spots – What Could This Be?One of my plants has yellowing tips on some of its leaves, and there are also brown spots forming on these yellow areas.
Any ideas on what could be causing this? Could it be a nutrient issue, or is it maybe related to pests or environmental factors?

Yellow blemishes1 week old seedling is starting to develop yellow blemishes on initial leaves. Soil is biobizz lightmix, PH 6.2 from bottled water with no nutes, 150w led light is at 50% and 25-30cm distance. Is it a cal-mag deficiency, light burn, genetics, or just too soon to worry?

PLEASE HELP! See former question as well.Continue to see deficency or burn in leaves. I have fed her only ph water for 2 weeks and it continues. I asked for help before, everyone just tells me what they think is wrong and not the reasons why. If you have an answer it would be appreciated to know your reasoning. Thanks🤘
