Could be easily be a calcium deficiency, as well as an out-of-balance pH. You seemed to have fed plants heavily also.
Other than that, it can just be a bad plant. It can happen at times. You can expect that even when working with clones.
It looks like temps and humidity are quite high too, given you're in 5th week of flowering.

I have the light at a height of about 40 cm. The photo is taken immediately after watering. The water drains as it should. I use biobiz lite mix. I think it will be poor water quality or spoiled fertilizer.
How do you recognize spoiled fertilizer?Week 1

Many of my plant's fan leaves, especially lower down in the plant are turning yellow. Is this normal? I think I'm on my last couple of weeks for flowering, so I'm not sure if it's just part of the process towards the end. Should I remove them, or just leave them there?Leaves. Color - Yellow

I have no idea what these brown spots are on my seedling?Brown/ rusty looking spots on seedling. Only thing I did was spray with a Epson salt and B52 foliar spray. The soil is deprived of magnesium so that’s why. I think I corrected by using cal mag. The sister plant is a few weeks ahead and showing recovery.Leaves. Color - Dark-brown
