So the epsom salt for mag except the magnifical is pretty much just a calmag already so I should add more epsom salt ?
yes
your plant is a mag whore
maybe drop the mag ppms down to 175-200 if your going to add both products...you can foliar and add at the roots but definitely at the roots
and get a microbe product and use it once a week or so
and picking off some of the lower leaves that aint doing much will increase growth and add better airflow...picking off the leaves , the plants root system wont have to support those leaves removed and can direct that energy to other areas....a few leaves dont be stripping it bare.
magnifical you say is a foliar spray (using it as a foliar spray) I imagine you aint doing it right are you adding a surfactant getting a hundred percent coverage under the leaves with the lights out ..at what ppm what sprayer , and how often, i know you dont have the kind of sprayer I use as I made a custom one that takes care of these things.(coverage issues). and how often.
you said you leach every nine days...so flushing every nine days...not a good practice flushing out all the microbe population...getting a microbe product and using it will take care of what the hygrozyme is doing for you and wont need to buy that which is expensive. Its a good practice to flush once halfway in veg and halfway through flower to remove any salt build up to prevent any issues coming from that ...renute add back microbes. I dont think every nine days is the right thing to do.
