Mag deficiency?

[Bean_Boy]

Hi everyone, I've searched and searched. Running masterblend with cal-mag, pH 6.1, EC 1900, issue were apparent before I upped the pH. I suspect she's rootbound from the peat pod netting, which I've removed. The temps here have been 80+

Any thoughts? Thanks in advance

PS, start of my 2nd grow, still very new

Edit: growing dwc with 5 gallon bucket, 240w led @ 50%, 24" above plant. Sprouted just under 2 weeks ago

Those peat pod netting are not stoping your roots.. Trust.. lol

Here's a better picture, I lowered the water level and increased the bubbles. Any thoughts?

Is this cause for concern? The new growth looks pretty good I think. The leaves are crispy

Thanks

I must be asking a silly question, I'll keep researching and experimenting. Thanks anyway for looking

I'd say yes cause for concern. I haven't done any DWC yet, but you said EC 1900. Not sure what scale you're working with, but regardless that seems way too strong for babies.

Thanks for the reply, I'll try cutting it back down. It's full strength masterblend, probably too soon. I'm trying to figure out how to dose as they grow.

Thank you!

300-400ppm is plenty at that stage.

Thanks Aqua Man, I'll dilute it when I get home

Just to report back, i cut the ec by about 30%. Comparing pictures, the leaves already look more perky with better color. Hopefully its not just a confirmation bias!

I didnt see this, yes it has a small clip on fan on low. I think i had wind burn last time, so im trying to be gentle

Yeah that's why I asked. Make sure it's not pointed right at them
