nutrient spray

[grantleslie1]

should spray nutrient be used on bubbletronic setup

[Green75]

No spray nutes should every be given...you want them to feed from bottom up...

In coco also Green?

[Green75]

Yes that's what I believe...and practice...Plants don't feed through their leaves in nature...for a reason...feed through root base so roots bang away non-stop...

[Flockshot]

Good enough for me.

Howdy grantleslie1,
I have never used anything but pesticides (Azamax) in a foliar spray, but I will agree with Green75 and his experience. I would think that one would tend to cause nutrient burn by feeding both ways and the only thing that I would think that could be picked up by the leaves (other than CO2 and/or O2) is the nitrogen absorbed by rain water falling in the plant (in nature).
Good luck with your grow.
