Anyone experienced purple buds after using Clonex?So I have this one girl out of 10, that is developing purple/pink buds. I thought is was genetics. But I just realised that I (unsuccessfully) attempted to reattach a broken branch at one point in week 1 or 2 of flower. I used clonex to give it some extra help. Clonex is purple.

TMV? 2 plants. 2 different symptoms. It's getting worse. I just flipped them to flower.They showed symptoms 2 days ago. Yesterday I changed the water with new h2o2 and nutrients. The symptoms have increased. Only other explanation can be pH swings. Because it's in hydro, it tends to have that when I change water and get pH down again. Is it TMV?

Should I quit, and start over? Still not out if it's root rot or just coloration from the larvea. Hydroponics had larvea infestation. Used h2o2, 2 days later my roots looked like photo #1. Now 4 days later, same roots look like #2. Had pH problems. lowered now. Gon look if its stable tomorrow. They should be ready to flip now. All other pics are also from today. Should I continue?

How much H2O2 do I use in hydroponics to fight a larvea pest in the roots?Like the title. I've seen a lot of sources, and they vary a lot. Is 1ml/L sufficient? Or double it, because the pest is established?

Buds turning brown The buds that have been foxtailing are turning brown it seems. I'm batteling spider mites and WPM. It looks like I got the better hand on the WPM but the mites have spread pretty bad. Is this because of mites? Or bud rot? Buds still feel firm if i squish them. Most buds are fine.
