can plants fully recover from a bout of deficiency? got 4, around day 19-20, all had yellowing on most of the bottom leaves, hit em with some grow big, hopefully they'll perk up in a day or two enough to move to some fox farms soil will the color return to leaves or are they permanently damaged?
i would repot them in fresh clean soil and give um a good watering.. Mine was doin the same thing and perked back up within 3 hours of repotting. and the outside of the leaves are slowwwwly turning back green I am not gonna worry bout ferts until flowering , this time. the Nitrogen Lockout stunted my babies so im gonna be veg'n longer , but at least I saved them
if the leaves start to curl under and draw up .. those ones r goners.. the bottom 2 leaves on mine did it but the rest is growin pretty.
