Seems like the wee ones have caught up nicely. You pretty much can't tell which ones were started first, except for maybe the white widow in the middle.
I have the same ligth as you,maybe it is ligth stress..I have had the same with my plants,and i had the ligths to close for a few weeks..some weeks after my leaves started to turn ligth greenish then yellow..then the lower ones started to crumble and fall of. I am no 100% but i sure looks like it!
Very nice 🌱🍒👌🏻 Try full dose of Cal-Mag in your H2O. And 1 dose of base ferts at 50% To your amnesia and give her a week. Looks like cal deficit to me.
Man this slut puts out more than the girls I dated in high school! Awesome grow, I'm growing this strain as well. You did a great job manifolding, leaving those buds heavy. Take it easy... pulling up a chair for this one.
