Looks a lock out related to pH. Maybe magnesium def stems are really red. What kind of soil and nutes

First thought is your pH still isn't right or Root Aphids

I never had root aphits only ever say some red stems and fixed it with ebsom salt mixed a tsp per gallon along with my gh nutes

 

[CaliRooted]

Still I'd look into it

You may be the winner!
I was trying to identify the little things but having looked, it's definitely root aphids.

Thanks my friend! Any genocidal tips?
I'm seeing pyrethrum and diatomaceous earth (I have a bag of this) and others are effective. Any better than another? I have soil so hopefully something I can use on flowering plants, in the soil

Ph locked out causing cal mag deficiency

 

[CaliRooted]

@Tasty Buds the damage from root aphids look like a cal mag or phos issue in flower

@ahemait in flower the only thing I'd use to combat is of biowar Foliar and Root paks make a Tea and drench at 100%

Yeah, I've had em in a warehouse grow. WHAT A BITCH!!!! PH, and aphids issued can manifest themselves to look like almost any deficiency. I, well the guy I was helping out at the time, had a BAD infestation in his warehouse. It's pretty difficult to ID an aphid prob by look of leaves. To get rid of aphids in a several thousand as ft area....ya gotta clean/throw away everything, bomb/nuke, and lose time.

That is a phos deficiency in the first pic. by ph swing or no phos. the spotting does look like MG because it is in between the stems of the leaf.

 

[CaliRooted]

It's not a deficiency, he has identified Root Aphids. Root Aphids mimic deficiencies

And REALLY SUCK!

I'd agree with that except the ph has been stable. I've had some issues starting seeds with my re-amended soil mix and I believe whatever this little critter is has been the cause. Clones make it just not seeds, which concerns me a great deal.

I talked to a greenhouse guy and he was emphatic that root aphids don't exist.
I didn't have my phone with me to specify phylo-whatever they were called, but all he had was an aerosol spray and told me not to water too much so the soil dries out, which is difficult in a top feed drip irritation set up : |

I read botaniguard is effective but in Canada one needs a license to obtain it.

I have a bunch of diatomaceous earth I can use for a top dress but that won't do much for what's in the soil.

I dunno. This is getting complicated.
