Need help in figuring out my seedlings issue

[Pparker88]

Leaves are getting blotchy and then dried and brittle. Seems like older growth. It’s in roots organic micro greens. QB LED 480W. Only fed water. I have not been PH’ing water. Could it be a PH issue?

Roots micro green has very little nutes in it. Fist I would give them a good foliar feeding with a complete nute formula. Then repot them in 2-3 gallon pots with something like ffof or roots original.

Could definitely be a pH issue. Also what's your watering schedule like? Is your medium as dry as it looks? What's your drainage on that cup like, does water flow easily from the bottom when you water?
But for real, knowing your pH is a big deal, the water you use and what the run off from said drainage let you have an idea of what the plant is experiencing. If you know what pH the water is you also have an idea of what it's going to do when it hits the medium.

That stuff isn't like the original roots organic potting soil, which is pretty good stuff. Yeah, I wouldn't say the same thing about their micro-green stuff. As that stuff always kicks up magnesium deficiencies whether you are growing a seedlings or a fully mature plant or clone in that stuff!

I’ve been watering about every other day. I don’t know about flowing easily. But drips out when I water. I drilled a bunch of holes on the bottom of the cups
