Foliar spraying friends, how big before you start?

Hey all, I haven't dabbled much in foliar spraying. I'm running Athena so I want to do some foliar feeding with Stack. Do these ladies look big enough? When do you like to start foliar feeding? I've got them on full strength feed at 1.7 EC once daily in straight coco.

You can foliar feed any time. Depends on what you want to accomplish. I avoid foliar during bloom. Not sure what Stack is or when to use it.

It's derived from kelp. I've heard younger plants from seed are sensitive to foliar feeds, would you disagree? I don't think I mentioned that I started from seed. I could see clones being ready at any time but again I don't know. I gave them a spray at lights out and they look happy today!

I have foliar fed two day old seedlings without a problem many times. If they are more than two weeks old, I wouldn't worry at all.

just remember to spray the under-sides of the leaves - this is were the plant "up-takes" nutrients. One can see this when there is "rain " in the air Oak tress trun there leaves up-side down to catch the rain
