leaves completely yellow, due to bad ph, how long to recover?

im about a 5 weeks into veg in hydro DWC, 80% of the plant went super light green, probably N lockout due to me not calibrating my ph meter

so I put in some N product, I fixed the PH. How long should it take for a healthy green to come back?

i think you can get foliage spray which helps with this, wish i could help more sorry
im in the same situation as you now almost killed my plants although they where only small...
i had 7-7.5 ph possibly even higher...

whenever leaf symtoms occur ie: yellowing, brown spots, yellow veins & nutrient or ph problems are encountered, those leaves never really recovered, they stayed like that. But the new growth was back to being nice and green and on track.

I hope so! I'm going to try some more foliar feeding see if it helps

I don't believe leaves actually 'heal'. Once damaged, they stay like that, as long as the problem is resolved, as opposed to continuing to worsen.

good to know
