Growing with Happy Frog. 5 gallon bucket per plant. Fertilize once a week. This is my third cycle. I started with seed. I noticed it on one of my 1st plants, seed plant. It didn' seem to bother any of the other plants. I cloned from then on. I didn' clone that plant. I noticed it on the second harvest, still seed. The clones of all the other plants did ok, then when I put them into budding, i noticed it coming on most of the plants. I harvested before they got bad, but all the new babies, they are about 8 weeks old and they are getting worse. I put an organic supplement with calcium, magnesium and phosphorus. The older babies that haven put onto the bud room look better, but not the younger ones in the baby room.
