Brown spots and pale leaves

Barneys pinapple express Auto grown in canna coco with canna a + b nutrients. I thought it was magnesium deficiency so ive lowered pH and tried adding epsom salts but problems persist. Can anyone help?

These seeds are garbage btw. Week 10 and haven't even shown their sex yet.

Bump. Anyone?

you need (N) and some (p) also PH those ladies View attachment 2285891the leafs are damaged and wont heal after that late of a def. however look to the new growth for signs of the plant responding !!!! and DO NOT cut the effected tissue off, as that mistake i have learned from. The new growth will show the plants health .. I run DWC so i can check the roots and in hydro the problems show faster! I ran coco and dwc has it beat hands down get a bucket and a air pump and a net lid and do this Hope this helps if you have any ? just let me know !
