Magnesium deficiency? If yellowing is less interveinal over time, then i'd say a slight N-def. Epsom salt can work too, if not too high in Sulfur already. Cal-mag is fine, if you are not too high on Ca already. May want to calculate ppm from your guaranteed analysis labels on your nutes. make an informed decision. consider recent behaviour and events that may not have been included here... in the end make sure you understand the decision you choose to take, don't blindly follow what i specifically say.

Looks like magnesium deficiency. If you are using RO, distilled, or rain water you need to add CalMag to every watering as those types of water do not have any of those essential minerals. Your two plants can vary slightly in what they need and it seems like this one needs more Mg

Upper leaves are yellow and not smooth I noticed leaves on top are closing and today are yellowish. Older plant aren’t stretching more, I thought it’s too much light or too hot but it’s kinda weird because light are at 40cm from longer plant and 50 from smaller, temperature are max 26C. So, it’s normal?

Older leaves are yellowing, brown/red rusty spots, dying tissue, red stems.Older leaves have brown/red rusty spots and looks like dying tissue in between the veins. Burnt tips, and yellowing leaves. The soil was really dry and my PH meter was 0.4 too high. I gave each plant 3L of water with EC: 0.0 PH: 6.4 to check runoff. Runoff was PH: 6.1 EC: 0.8

What is this leaf showing?Anybody knows what is going on with this plant? My first guess was nitrogen toxicity because of the leaves clawing down a week ago, but I am not fully sure anymore with how the leaves are looking now.
