Critical XXL (Zambeza)

@BillMonroe, I've had 2 battles with those s.o.b.s. I had 1 outdoor in flower and I sprayed it with a hard mist setting on my spray nozzle for the garden hose and sprayed them all off. Read it somewhere and didnt think it would work but I never saw another for the last 10-14 days(nights were real cold too). I also used water/alcohol solution and sprayed the indoor plants effected. Couldnt beat em on 1, appears I did on the other. I removed all the effected area since I had just switched to 12/12 that day and sprayed thoroughly with alcohol. I used straight 91% isopropyl cuz I had used 50% for weeks on my 1 in flower with little progress. 91% worked but I scorched it real bad. It almost looked like the alcohol got in the leaves thru the mite bites and fried them. I'd try 75% alcohol next time and not drench the leaves. Sorry for writing a novel but if it leads to 1 mite being killed it's worth it. My #1 enemy on earth currently lol.

@BillMonroe, I think you’re on the right path. Best of luck!

@DudeGrowsWeed, thanks, this seems like the best approach so late in flower. I haven't come across anything that can be safely sprayed at this stage. I ordered some predatory mites that suit my environment. Today I did not find a single living thing after looking for half an hour, but I know the pests love to hide. I'll treat the room with the methylated spirit solution and set out some hunter mites after the weekend to try and cull any remaining or coming populations

@BeefWellingtons,thanks :) No idea when it will be ready! The breeder says 55 days so it might be 2-3 weeks... time will tell!

@Kirr38, Good point, I probably should not call that a deficiency 😊

@Experimentgreen, I added some pics of the roots on this one. Entire pot filled with branching webs of thin stringy roots and some bigger ones. I had to pull the soil apart with force. I manually pruned the taproot of this plant at the bottom of the jiffy. It grew all the roots out of the sides of the jiffy

@Experimentgreen, Look at these roots, on the left is regular pot with drainage holes, on the right is 1 liter airpot: https://growdiaries.s3-accelerate.amazonaws.com/static/post/photo/7325/545030_pineapple-chunk-critical-xxl.jpg (3 week transplant) Much better roots in airpot and better plant growth. Packing the sides tightly with soil before adding it in the middle of the pot will prevent the water running out from the top holes. The pots have a learning curve but are very worth it After transplantation the roots from the regular container just started growing out from the soil as some of it was traveling upward due to the circling. The airpot already had roots coming out horizontally at just a few millimeters under the surface. i think the fabric pots are great too. What I like about airpot is that the bottom is lifted up off the ground... excellent air pruning at the bottom. when you see waves of root tips there you know the plant is creating lots of nice side branching roots

@Experimentgreen,Yep I will take some pictures of the roots :) I'm quite interested too... I tried 2 stages of root pruning, first in the jiffy (manually pruned the taproot), then in 1L airpots. The execution is a little lacking but I am inspired by this youtube video - Root System Basics by RootBuilder. Their method is to allow a plant to develop lots of root sin a 4x4 inch area before transplanting. Some growers have put it to practice. Your plants are looking absolutely immense and I can't wait to see them in flower (I'm sure you can't either)! I think such a large volume of soil allows the plant to grow much more freely like it would in ideal circumstances in nature.

@Mrs_Larimar, thanks, I certainly hope so! Like you said there will be more somewhere... hopefully the predatory mites are able to find all the eggs.
