I'll just get to it guys;

1. Does it (Epsom or English salt/magnesium sulfate) work as a mold preventive substance? how effective it is?
2. In which scenarios other than Mg deficiency should it be used?
3. Should and how will it intervene with my flower feed in terms of (N)PK uptake?
3. Application wise; my brother insist on spreading it as a top dresser, just covering the rootball diameter for longer/slower release targeted on fighting mold and rot. We saw similar applications on tomatoes but never on ganja. Just to make sure, we first tested it on a smaller pot/plant and also applied it the same way on some beefsteak tomato plants -no harm done. what do you think?

my ladies are looking super healthy right now (except one that is showing mild interveinal chlorosis), so at this stage i don't want to play with their diet too much if it means having to deal with damage control afterwards.

Thank you fellas!

@royfree2grow I too grow in a small space atm, got 8 large bushy plants in a 3 x 3 feet grow tent, its heavily overcrowded, but I use a oversized extraction fan to keep a high airflow through the tent, and also a large circulation fan on low speed that covers all the plants making sure there is no areas where the air stands still, I added extra perlite to my soil to make it more airy, and then I let the soil dry out every now and then, but if its a question of saving a grow I would also use every method available.

How about a small fan at the base of the plants to keep the air around the pots and over the soil moving?

MgSO4 provides *more* S than Mg. I've never used it for treating or preventing any kinds of molds. I would *not* use it as a top-dressing, as a salt it I believe it would desiccate or damage any roots it comes into direct contact with, and as it's *so* easily dissolved in water, I see no reason to use it any other way (dissolved in water). You also have much less control of how much is going into the soil at a time when doing it that way, all around it just seems like a practice that's bound to fail at one point or another to me. I feel the same way about sea salts, and I use them fairly often.

Do you have H2O2 on hand? If not, you should. Also, isopropyl alcohol. Both products can be used directly on fruiting bodies with no harm to the plant (don't put on roots). Milk applied as a foliar at a 10% dilution is also known to knock out some species of powdery mildew (you don't say what mold you're working against here).

And as far as locking out other minerals, yes, you can if you use too much. This is where foliar application can come in handy.

I believe the product you're going to want for bud mold here is Serenade. Look through ncga's posts.

with mold Ive had great success with foliar teas stacked with different bacillus strains (serenade is B.Subtilis, there are a couple others) and Actinovate, if you are using foliar anyway its an easy addition. They can also be watered in
