I've never tried foliar spray during flowering...are there any experienced growers that use foliar spray during flowering If so how often and what time of day? My plants are just now enter a few weeks into flowering and have lots of white hairs so far just have heard a lot of negative about foliar feeding during flowering mostly mold problems Sent from my HTC One using Grasscity Forum mobile app
I avoid foliar feeding during flowering for exactly the reason that you mentioned, mold. My grow space stays humid enough as it is, and as long as your plants are receiving enough water through the roots, it's really not necessary IMO. Just make sure you are getting plenty of air flow to allow for maximum transpiration through the leaves. That will assist with the uptake of nutrients and water significantly.
