I wouldn't worry about it, no plant will ever have 100% perfect leaves, 100% of the time. It is just a slight cosmetic blemish.

Maybe black leaf spot fungus. Has your humidity been high?

1 out of 3 doesnt do as well as the others
Im just wondering why one out of 3 plants, does not perfectly well while the others seem doing awesome. Can it really differ from a strain that it shows signs of light stress or nutrient burn while other plants seem to do well with it? I added 3 pics, 1st one showing the meh one

What are the brown/gold stripes from?
Does anyone know what this is? I am reading that it’s a Mag deficiency, but I did a reservoir change yesterday and put more CaliMag than last time, so I can’t see how that makes sense. PH is around the same, 6. I did add some PH Down directly to the reservoir, is that the issue?

Why are all the leaves on the upper half of the plant perky and the half way down start drooping off? Even the ones getting plenty of light. The soil is not that dry yet either.

I noticed that the lower 2 leaves are yellowing and I think that are a little crispy. I topped the plant at the beginning of the week ago and I removed the first pair of leaves three days later ( yesterday). Do you think is this a problem? What can I do? Thank you. Peace
