I was writing in another thread, but I wonder what other people think about foliar feeding? Here was my post, and yeah this guy was having a problem caused by his foliar feeding;
Foliar feeding is like Voo Doo magic with very little data to constitute it's usage. It basically just generates income for the shops, and manufacturers.
Mari Jane isn't really designed to absorb nutes, or minerals through it's leaves. It can do so in a very limited capacity, but in a grow room you'd never need it, and think about the possible negatives? The way foliar feeding works is you are allowing the stomata to absorb nutrients. That's not really what they are there for, they are to exchange Co2 to oxygen, and just breathe. The system the plant uses to draw nutes, and water through the roots depend on the stomata as well! I think the risk of clogging the stomata, burning the leaves, uncontrolled moisture, and a myriad of other negative possibilities (look at your example!) far outweigh any perceived benefits. Plants just don't eat like that, and there is no reason to mess with it. You should have no problem delivering all your plants needs through the root system. Just look at the way the thing was designed by nature! Your time would be much better spent trying to deliver MAX air exchange, >75 degree temps, 5000 lumens a sq foot, proper PH for your medium, and a great root system. If you nail those five things you can deliver a tremendous amount of nutes to your plant. I feed very heavy, but I've got plants that can actually utilize it.
I have used foliars before, but just for a few specific reasons when I had to deliver something to the plant in a pinch.
