Leaf question with pic

My babies were doing well. This morning I noticed an odd pigment change in both sets of bottom leaves. What do you think this is:

Thanks guys. I was holding off on nutes. I guess it's time.

I concur. What medium are you using? It looks like all perlite.

 

[Girdweed]

25% Vermiculite and 75% perlite

It's my first attempt at hempy's. I was waiting for growth to slow before starting nutes. I guess a p deficiency is a good indication to start the juice.

Wish me luck.

Is there anything extra (aside from starting nutes) that I should do?

Make sure your pH is spot on.

It's 5.9-6.1. Is that OK?
