Lower Leaves Decaying? (pics)

My plant has been doing pretty good for the last couple weeks until I noticed that the lower sets of leaves are starting to turn yellow. I didn't think much of it until I noticed today that there are now brown spots on the lower leaves. What should I
do?



My setup is in this thread: https://www.rollitup.org/marijuana-plant-problems/344875-nutrient-deficiency.html

I've since flushed it with pHed water (week and half ago), transplanted to a larger pot (5 days ago) and foliar fed it epsom salts (2 days ago).

bump..can anyone help?

This to me is looking like a N def.

Have you tried feeding with a bigger concentration of nutes.

What strength or EC level are putting into it at the moment?

dude i just had this problem , my well water was all fxxkd up like 5.0 so i had p.h lockout. I foliar fed with some humboldt verde it had alot of nitrogen, my plants werent getting nutes like they should b/c of the lockout. I would check the ph if its bad flush, go get some ph up and foliar feed them something with nitrogen. I lost most of my fan leaves but the new groth is coming back good and green,kinda looks like overwatering to i did the same thing hope this helps.

lol... it's over watering .. look at your stem... it's damn near purple

I haven't watered in a week.

what kind of soil u using?

are u using MG cactus mix? if so ...u giving it nutes too... and your foiler feeding it... MG has time realese nutrients.. your over doing it
