Morning OP-

The plant gets extra food over the nutrient EC maximum. I figure that's gotta be a good thing. I'm forcing food down the stomata. Is this naive?

Just watch yourself- it's really easy to OD and fry yer shit ( talking crispy fried), esp w/ N. The plant gets extra nutes, which it may or may not be able to handle.

Are you saying that you can actually increase the thickness of the foliage, or is it like the cellular structure, or well what do you mean build tissue levels? Is this done with silicone? Lord I probably sound like an idiot.


Not at all- we're getting into weird science here. Referring to relative concentration of elements in tissue, tho foliar application of silica is associated with a thicker cell membrane. Silica, not silicone...

What do you recommend I foliar spray to improve the iron content.

Any good micro supplement will do the trick- see if yer local carries a product called " Spray & Grow". I like the citrate, rather than the EDTA, but that's a mighty fine point. Lotta liquified seaweeds are iron fortified these days, as well.

If I understand correctly, youā??re saying foliar feeding doesnā??t work well for the macros like N,P,K but it does for the micro nutrients?

Really more a matter of it maybe working too well- beware the fry factor.

One last thing I've been wondering but keep forget to ask. Can you basically foliar feed with anything you feed the roots with? With the exception of the macro nutrients not being absorbed as well, would the micros be about the same thing? Bleahg - I can talk, what I mean is, can I mix up my grow nutes and foliar feed with them during the veg cycle, and can I use my bud nutes to foliar feed during the budding cycle? Etc.?


Well, full strength nute will almost certainly fry leaf tissue- I'd cut it down to like 10% dose. Try to avoid getting flowers wet too often, as it can lead to fungal issues. Do yerself a favor and don't spray mollasses, or LK, or anything w/ a high sucrose level, as it will leave sticky surface sugars which will attact bugs and bacteria.

Again, I don't really think of foliars as a primary source of nutrients, except in truely esoteric circumstances.

Just 'cause ya can, doesn't always mean that ya should...
