do you think cal-mag will fix the problem because the problem all started when i followed the food instructions and overfeed my girl

You are using OR with out any cal-mag? I use OR myself and use Botanicare cal mag at 150ppm . So I would say yes that should fix your issues.

thanks how long do you think before i see results

OR water? i think you guys mean RO"reverse osmosis".

the damaged leaves will not heal themselves.

you should be watching the new growth.

So would it be a fair assumption to make that u think it's a cal-mag problem

This right here ... your plant received an N overdose. Do not feed for at least a week.

The "OR" thing looks French or Spanish to my eyes ... cn

yea i didn't say it was a cal/mag defiency.

just saying in general any damaged leaves will not repair themselves.

whats nice about DWC/RDWC is you can dump out your nute water and start all over.

you never did say what system your running..care to elaborate.
