Clones showing yellow on lower leaves

[SD1]

They are in 50% humiditiy, 77 deg. and potted in fox farmss ocean forrest. Book says no nutes but lower leaves yellowing and looks like low nitrogen. What to do? They are about 8" tall and growing well to this point.

On a side note, we had a blackout for almost 12 hours. Temp stayed constant but NO LIGHTS for that period after having been on a 24hr light regimen. Any fallout from this?

Give them fuckers some ferts. General Organics is good.

Dont know what book your reading, but sounds like they are due for a low dose of Nitrogen

I have some HG soil A and mixed up a solution at 1:200 per instructions. That or since it is already showing some yellowing should I get some water soluble N??

How tall were they when they rooted? How long ago did you transplant into the fox farm?

I just realized this is in outdoor and I meant to post in infirmary. I watered with GH soil A/B with 6.5ph. I will report back.

On a side note, I noticed my smaller clones, the blue dream and blue satellites were ilongating as they were further from the light than the trainwreck so I put them on a shoe box so the canopies are all equidistant from the light.

I feel like a worried mother. :sweating
