Hemp russet mites or what?

The heat knocked them back but one tratment did not irradicate them. I am likely going to limp through and finish these two plants in flower after doing another heat treatment in a day or two. Also based on what I am reading I should be spraying something inbetween heat treatments.

I almost feel as if I brought these guys with me in rols. Had major issues at new location using some old soil nixed the soil went hydro went through major decon and did bare root transplants from soil to hydro. That gave them a speedbump but nothing more. I think this issue has been going on for mor than year before I think I finally identified it....I hope.

One way I've found to see if it is Russet mites is to take a small bud or leaf and smack it on a white piece of paper, then immediately wipe your finger on the paper where you smacked it. If you see small light brown "blood like" smears on the paper it is almost certainly russet mites. They also like to collect towards the tips of leaves as well. Im not sure how effective the blast of heat will be in short bursts as any heat treatments Ive read about regarding Russets have all been for longer periods of time and followed by a complete shut down of the room. When I got them I had to go full nuclear assault with multiple pyrethrin bombs and shut my room down for a few weeks with no plant matter anywhere for them to survive on....which unfortunately included tossing any plants I had in that room (including a killer Kosher Kush momma I had that I still whine about). I got mine from unquarantined cuts from a "trusted" grower.....-lesson learned. I truly hope you can get to the bottom of the issue and remedy it without much loss.

How long on the heat I was over 100 for 4 hrs during the warm up and over 120 for 1.5. I read over 120 for an hour but perhaps I cooled down too quick? I will start during night cycle and hold longer because the plants can handle it.

The collection at the edges of leaves is what I think that spittle is. I notice some collection of spots there too.

I have no personal experience using heat so dont let me lead you astray but from what I've gathered from the googles regarding the heat method is that it should require days of those temps. The bugs reproduction times are relatively fast and they "drop" their larvae when in distress in an attempt towards survival. You have to have a cycle long enough to induce the stress to drop larvae and begin slowing/breaking the breeding cycle. Same as with the bombs. You do the bombs every 3-5 days for 3 cycles. The first bomb distresses and the adult/mature Russet mites drop larvae in a preservation attempt against the present "distress". The bomb contents kills off the parents, but isnt effective to the larvae that were dropped. 3-5 days later you blow off bomb #2 and this kills any remaining adult or larvae producing mite that may have survived the first bomb. 3-5 days later you blow off precautionary bomb #3 and sleep well at night knowing there was no chance of any adult stragglers, and by now (9-15) days later from the initial larvae being dropped (and none made since initial drop), those initial larvae have failed to survive in such conditions and will hopefully fail to lay dormant until conditions become more favorable for survival. My take on it is just replace the bomb with heat and it is the same theory.

Watch yer ass following sulphur treatments with ,,, crap ,,what was it?
I forget. Phattysoap follwed by sulphur?
Was bad.

That heat certainly cleared up any Pm.

The CO2 helped plants survive the heat.
Full blast lights on during that shinangin , eh?
One must supply fuel to match the increased metabolism brought by heat.
Lotsa miosture in the soil, lotsa convection across the leaf surface.
This is top fuel class, dude, you gotta get your rpms up before you fog that nitros.
Full bore bro.

Ps, the Lpropane is addicting:ROFLMAO:

I tried the paper smear test a couple times with different buds there may have been one smear. Not conclusive but given the situation I gave orderd grand evo and vinerate and will likely go systemic on the veg plants.

Veg tent will probably get removed and discarded.

With exhaust being shut off there was no real replenishing of co2 thats a negatory on full blast lights in fact I will probably turn them down next time. I realize that impacts transpiration but the objective is to high a high canopy temp resulting in a high lst to pop the suckers and their eggs. It seems one of the only methods with a control factor on 2 stages where sprays are generally only effective on adults. Plus the heat leaves no pesticide residue. I am tending to agree with red though it can be applied similarly to the bug bombs. I intend to rotate in the grand evo and venerate but also realize heat treatments will probably kill them off too. Ultimately I am going nuclear on whats in veg as it is the seed run stock for blueripper tribute.

A little better pic of the spittle.

It is not like what aphids leave behind and dosent wipe off like condensation. It shimmers but that dosent show in the pics which seems to be commonly reported with these buggers.

I still am not sure what pest this is. Damage looks like damage from suckers.

Grandevo and vinerate should be here this week, those will become part of ipm for plants in veg. I will have to evaluate use for flower, will probably test on the od as I know there a billions of mites around I think I need a broad based approach. Also they may have to come indoor to finish.

Went hard at them yesterday in prep for todays heat treatment. Fed them some asprin and put a couple jugs of water in the freezer for the res.

Hacked back veg too in anticipation of forbid application but will be waiting until flower room is cleared, pull the veg tent, heat treat, clean, then go for the full frontal.

Keeping close to 80 overnight, have to grab propane tho before we get started.

Looks like I am 9 days out from the previous treatment. Right at 90 now just on electric heat. Propane would get me there quicker but not sure that is a good thing. Guessing I'll be approaching a hundred in an hour or so.
How this ends? IDK stay tuned.

Pretty sure I said I dont condone my actions, however, one precaution, in addition to proper air monitoring. Is one of these.

High pulse low pulse ox. This after 2 min. Can take 10x or more longer to recover.

Edit that reads 90 for pulse ox and 96 for pulse. My resting is under 50 bpm and under 94-96 isnt good wven for a smoker.

Thanks for lookin out. I will be honest I don't know what they are..,thankyou for your persistence @LittleDabbie those 2 links were very helpfull. I would not typically allow anything to get to the point of those pics with the yellow masses (except if you witnesed my testing od @thenotsoesoteric 's dbb that spider mites engulfed where they avoided welchie sorry eso.)
