Sour diesel and an Enigma

One issue with predatory mites in late flower is they can get stuck in the sticky trichomes. There is no easy solution. One option would be to use a contact kill pesticide but wipe it on the big fan leaves where they hang out vs spray, it would knock the adults dead and doing that multiple times till harvest would keep them in check. The risk of it touching the buds is the main draw back. but some pesticides have a short half life and are gone by the time you need to harvest so any of they rated for use in flower could work. just don't spray. wipe/paint it on the leaves. Sticky traps are best static options with no issues of making the buds weird with chemicals or mites. Can also treat the soil line with some DE or spray on some pesticide. this way the young ones coming out of the soil will be targeted. BTi/BTk I think targets the thrips in the soil so that's a easy and safe method of killing them. Use a strong concentration of it. Nematodes are also an option. This is also a good lesson on having some form of IPM or integrated pest management system in place. Introduce the mites/BTi early in veg so they can chill out and wait for a tasty meal. I saw some thrip dmg on my outdoor plants and got a bunch of mites in little sachets, they cleared em all up but again not in bloom was in early veg.

Stop feeding now and give just plain water, in normal amounts and at normal intervals until harvest time.........the plant will "flush" itself naturally once you stop giving fertilizers. There is no need to drown your plants with gallons of water, this does nothing special and can even be harmful.

You've got some beautiful flower there. Well done. Personally, I'd leave it another week. Hard to tell as pics are a little blurry, but first shot looks like the calyx still have some clear left in the otherwise cloudy trichomes. As for the volume of calyx' they look great, but could probably swell a little more. Third pic shows a fair few white pistils (could be strain specific to throw new pistils out at end of harvest), personally I'd wait for more of them to be browned and shrivelled. Just my 2 cents, but given you're under the reccommended time to flower - I'd feel confident pushing a bit further (as suggested harvest windows are typically shorter than necessary so seed-companies can profit further). Might be good to know what kind of strain you're growing - what medium and wheyther it's photoperiod vs. autoflower. Happy Growing and Congrats on the great work so far!
