Is My Diagnosis right?

Ok she is hydro with GH nutes well water day 16 in flower These are the fan leaves. the smaller leaves is unaffected. air temp is 74 water temp is 60 ph was adjusted to far and ended up at 3.4. so i added a little baking soda and adjusted to 6.1. PPM is 1504 .The way I read this is Mag lock out due to sodium toxicity. Used Epsom salts for mag. Will be going to hydro shop for ph up and cal/mag whats the diff between ph up and baking soda and cal mag vs Epsom salts. I will be doing a rez change in the morning as its to close to lights out. It looks at if its in the early stages.

I'm NOT a Hydro grower, but that's def a lockout, Possibly salt related.


If your invested into it deep enough to be running DWC with any nute line you should be using the proper tools for the job!

PH DOWN is Phosphoric acid, not sure what PH UP is, but I'm betting it's NOT baking soda ;)


CalMag is basically Molasses ;) http://boards.cannabis.com/basic-gro...oodness-2.html But having a CalMag Hydro additive on hand is probably the best way to go.

I do have Black strap Molasses and ph down. Baking soda can be use
Should I flush with straight water for a day then go back to full strength nutes?

im thinking it was your ph, deal 3.4 is very low. flush then ease back into nutes let them build up again. its like eating after your sick youll get back to your regular diet in no time.

in the middle of a 24 hour flush then i will go 1/2 strength nutes till next change.then full strength. This will prolly effect yield.
hopefully not by much
