glossy bronze-colored spots

Hello. I found an oddity this eve in the garden...just a few leaves are showing spots on the one plant. Little glossy spots, kinda bronzish to my eye, and visible as a sorta dark, stain, on the bottom.

A pic of the leaf, then the underside of the same, a couple of the the plant..

This is Nirvana's Papaya, one of four to be sexed...it went germed into soil on 9.23 and it's (as a strain) blown past everything else that germed before it. It makes me very happy...

Sunshine mix #4 soil.
Hydroshoppe nutes, 1/3 strength every other water
t5 lite

Thanks for your look and welcome your comments.

Peace

bump to the top... trying to get the doctor's attention...

I think the spots are getting worse...is there a doctor in the house?

paging Dr. Ganja. Dr. Ganja, report to the nursery for diagnostic services, please.

Fuck your plants look healthy as to me..... I wouldnt worry to much. Whats your ph?

looks like could be ph being off. they also look just a teeny bit on the light green side-what fertsa re you using?

my ph is...probably a bit high. I tested the water and it's pretty close to 6-7...but the runoff I managed to capture seemed closer to 8...

I got the cheap kit where I drip drops into a my liquid, then I gauge it using my eye... so I can only check runoff water, and it's a pain in the ass cause I'm using cloth grow bags...so there's no drain hole to catch a bit of runoff in, I gotta just kinda fake it... plus my eyes are red from ganja smoke, so I know that I can't tell what fuckin color the juice is...

anyhoo... I guess I should invest in the digital ph jobby for the water and the soil ph probe jobby for the container? And then ph up and down to adjust my water? Then feed ph corrected water/nutes until my soil is correct?

Or...?

whew...these unforeseen startup costs are killing me...

using these nutes. local hydro shoppe says I needed them while my head was spinning from all the other ish I purchased that day... I don't know anything about their brand quality.

so then, lets say for arguments sake that my ph is off...then what is manifesting as spots in the leaf?

Thanks again, y'all.
