What’s this. Can’t seem to figure it out.

[Newb2indoor]

So I transplanted my two white widows yesterday. And woke up this morning to one with some spots that have since progressed. Everyone else looks fine.
100%Coco coir
Gh flora trio based on ppm not bottle directions
1xdaily fertigation ppm under 300 to runoff for these specific girls
Rh 50-60%
Temp 77-80 day down to 72 at night
Checked the calibration on my apera ph pen and it was off by .5 (fucker) so this transplant got one fertigation at 6.8 but it also suffered minor root damage in transplant.
What’s up with her. Was hoping I could figure it out on My own but I can’t.

Have you checked for mites? There sure are a lot of little white and brown specks on those leaves. Zoom in and look at the leaf that's in your hand.

I’m gonna spray them to be sure but the brown is the coco I stir up every time I crawl in my grow tent. The white is definitely not bugs just checked with my loupe. Not sure what it is. But I work construction so could be anything wood, Sheetrock, insulation. I don’t see any signs of bugs other than the springtails in my coco. Treating them wouldn’t be a bad place to start.

I'm not familiar with ppm but I know it's around 0.4/5 ec?
My initial thought were they look hungry, I'd be feeding seedlings 0.7/1.0 depending on the stage, imo you need to up the nutrient strength to around 0.9/1.0ec (or equivalent)

I will try that. If you’re using the 500 point ec scale then these girls are at .5 to .6 right now. My bigger girls are at 1.2 Tomorrow morning I’ll start working these girls up to that.

I'm not sure about the scale bro but ime 0.5 in coco is to light.
I'd expect your other plants are looking fine with 1.2

Yeah, leave the springtails be if the are there. They are harmless.

Yeah my other plants look a lovely shade of green I guess I was afraid that these ones were still quite small to bump it up. But that’s exactly what I’m gonna do.

Yes the springtails are best left alone you're likely to do more damage than the springtails ever could, they're harmless even benificial, they eat dead and decaying matter and shit out fertiliser lol

Love em! Yeah I’ll just do a foliar neem oil spray and leave those guys alone.

Not surprised you're have an issue.
Your fertigation is at the wrong pH.........should be 5.8, not 6.8.

 

[Newb2indoor]

Yeah I religiously pH between 5.8 and 6.2 but it got one watering at 6.8 after transplant before I recalibrated my pen. I noticed because I always pre-mix a two day batch of water and when I put the pen back in its pH 4.0 storage solution it read 3.5. So I freaked recalibrated and corrected it but honestly they could not have gotten more than one watering at the wrong PH because of how I mix my nutrients.
