a few yellow leaves with small dried out patches

[jambon]

Hey gang...my 2 plants at 5 weeks old are pretty healthy looking besides 2 or 3 leaves have a yellow tinge to them and are get some dry brown spots, just small. it looks like a deficiency but what? I am using bat guano tea for feeding with a bit of kelp. The last two feeds I added some chemical flower food... I didn't want to but it has many more micro notes added. I just don't have the smarts to pinpoint the problem.
Any ideas out here? Thanks

Hey Jambon

See if you can get a picture up.

I'm not the best with deficiences, but what you're describing sounds like a cal/mag def.

I'd stick a picture up and wait for an eagle eye to set you straight with some solid advice

Hi Jam'- This looks like combo Ca-Mg, like Blue said... it has the typical small brown spotting of Ca defc., and the yellowing Mg defc. can bring,... plus, I think these are older, lower leaves? Some of the yellowing may be from lower light levels, and the plant is just shutting them down, starting with removing what nutes' in the leaf it can,... Mg is mobile, Ca, very poorly so,.... It's a sign that maybe some supplemental Ca-Mg is going to be needed! An easy fix, and one of the most common nute' deficiencies.... got some Ca-Mg supp's? or even molasses? the soil 'crobes would love that as well... :smoke:
