Magnesium deficiency affects old leaves and sulfur deficiency affects leaves all over. I don't understand what epsom salt is supposed to do.

Epsom salt I was using to correct sulfur deficiancy but now its clear by your link that is not a sulfor but more likely Iron deficiancy,

what I think Ill do now is use “canna bio flower” organic nutrients so that prob will give me some micro nutrients to my planta as there should be potassium in “canna bio” so that might help and also gn spray with epsom salt just to make sure :wall::peace:

I'm going with the soil ph being the problem. I use humic acid to help keep soil ph balanced...it works so well I don't even own a ph pen anymore. I use RAW humic acid starting at week 3 of grow and every week after...during flower I add their kelp too. It won't matter what nute you put in the soil if ph is off it will just add to the problem.....try it and let me know how it worked for you!

I use the RAW brand humic acid at 1/8 to 1/4 tsp/gal and I add their kelp at around the same dose a bit more during flower. Once/week but more often is fine too..it won't burn....It will make all your ph problems go away though...forever!
