Hi Boo! I grow outdoors, in fabric pots, in soil also. It’s been hot and humid here too. When watering with MC I am doing a feed/feed/feed/water. I try to get between 10-20% run off. There is thread on here that I believe
@InTheShed started, that was a discussion he had with a Pro Mix guy. The quote that I remember from that thread was:
“Generally, a good practice...is to irrigate with fertilizer solution three times and do the fourth irrigation with plain water to leach excess nutrients/salts. This would be applicable to all growing media.”
Also, about once a month on one of the water only days, I put 1 tablespoon per quart of Monterey Garden Insect Spray with Spinosad in the water as a soil drench for spider mites, aphids, etc. There is some debate as to the effectiveness of this, but so far I haven’t seen any negative results.
