"No prob. Sarcasm is hard to translate at times." damn , that sounds kind of sarcastic ???jk ... Legal, any idea of that one plant that didnt like foliar the other day? Wrong mix? Give a heads up on that scenario... My ak-47 just didnt like it, all other strains were cool with it... Similar situation?

Anyone tried an additional light source coming from the ground/below the plant to expose the underside of the leaves and stems to light? Im wondering if the same principles from foilar feeding apply to light utilization. I got a 150 watt light essentially on the floor to develop some smaller growth to supplement a 1k from the ceiling, see what happens

My point wasn't to offend you. It was more to stop other people from citing Jorge or Ed Rosenthal for that matter as if they were gods fucking gift to marijuana. Not saying you did that, but others often do. Need to thicken up that skin a little bro.

Fucking n00bs are always so sensitive LOL :)

But anyways, I foliar feed all the way through about week 5. I use a somewhat custom blend of liquid karma (4 ml/gallon) and this locally produced amino acid sugar solution which is basically just fancy molassis and some kelp additives (5ml gallon). Mixed with DM penetrator, sprayed with lights on twice a week.
Sorry man. I was a little stressed to begin with, probably should have reworded things. No hard feelings on my end though, and I agree that Jorge shouldn't be everyone's standard reference point. He's pretty good, but very inconsistent.

You think Rhino Skin would help?:wink:
 
how is DM liquid light 0.15-1.1-2.7
and DM penetrator gold range grow flower 0.008-0-0.003
I just picked these two up, the directions say,,,,, Add 4tbsp of each per qt of non ph adjusted h20 ???
is this a recommend mix.

i also have b-1 red and green thrivealive, sugardaddy, awesome blossoms, magical, bc boost, grow and bloom.. Does anyone have any recommened mixes for foliar spray during bloom
thanks

ok,, so i sprayed a mix of>>> 1tbsp liquid light + 1tbsp penetrator + 1tsp sugardaddy + 15fl.oz. h20

After years of gardening, I've rethunk my view of foliar feeding or using it to correct nutrient disorders. There is no art to foliar feeding and no real value compared to uptake by the roots. This busts the myth regarding the value of foliar feeding, where "it" all started, etc.

Wow. Great link/ article. Thx for posting
Ive been looking for a thread like this forever, awesome thank you
 
so it seems like the hairs on the tops near the light didn't like being sprayed. should the hairs not be sprayed ever? just leaves??? thanks

Don't spray your buds at all, just the leaves. You really shouldn't be foliar feeding late in flowering just because of the moisture it puts into your buds from ambient humidity. Plus, any residues will still be there when you harvest.

Yep, that PDF link is the type of solid, factual info growers should seek, but most take the popular route resulting in the blind leading the blind. The subject heading of this thread is a turn-off for me.

"Any benefit from foliar spraying of landscape trees and shrubs is minor considering the cost and​
labor required"

"Species differ widely in their ability to take up nutrients through their leaves. Differences in cuticle
thickness, stomatal resistance, and other genetic factors will influence uptake, as will environmental
conditions. Plants in a protected situation (like a greenhouse) have thinner and more porous cuticles than​
plants in the field and take up foliar sprays much more readily."

this paper is bias and talks mostly about trees and shrubs for the common homeowner landscape. for common landscaping around the house
time release fert, proper ph, and good soil is all thats needed.

If your growing pine trees and landscaping shrubs.

Explain why the dude with the tomato plant field says it works? I wonder what farmers that own apple and cherry orchards take on it would be. How bout sow beans?

I dont folier feed all the time, but when I do they look alot better the next day.

All my plants are big right now, but on my next run I will do a side by side using this method with identical clones.

As I stated earlier, I don't foliar feed unless I need a quick fix. However, you can find studies to support almost any claim these days. The link below is to a Maximum Yield article discussing the benefits of foliar feeding.

I might have to pickup a bottle of this,

So I was curious about foliar feeding and after reading this thread, decided to give it a go. I mixed 1/8 strength nutes with R/O and appied at the beginning of lights on. Only 1 week into flower. After just 2 days the leaves have perked up, and are looking quite a bit healthier. I'm sold!

or perhaps he suffers fools very lightly.... a while back he was taking some major hits cause he doesn't side with nute companies that spend alot of money on fancy names and graphics and would rather see more plant science involved... he sent me on a journey that has resulted in going organic and folks, beleive it or not... way cheaper.....

Yep, it's all relative. IOW, it's about about plant requirements, nutritional needs, dependent on growth rate. A grower's first focus should be on providing nutrients to the root system, as nature intended it to be.

No, I don't suffer fools lightly. Check out the YouTube a member posted, it hits "popular" thought right between the eyes LOL. https://www.rollitup.org/advanced-marijuana-cultivation/267989-uncle-bens-gardening-tweeks-pointers-39.html

Speaking of organics, I just picked up a truckload (literally) of a friend's compost and got the analysis back from the Aggie bio-solids department. What a frickin' excellent profile! 13-5-8 NPK with the proper amounts of Ca, Mg, Zn,Fe and the other micros. This is what every grower, cannabis or otherwise, should seek - someone you can trust where you can buy a lot of compost cheap, and it's quality stuff because of what goes into, and I'm not talking Eye of Newt or some other crap like electrolytes. If you have a pickup and/or trailer and someone with a horse farm they'll load you up for free, just to get rid of the chit.

Sorry, but 1/8 strength will have no affect, one way or the other, especially if you're using typical (watered down) "cannabis specific" nutes. Even if you have a high analysis food, say a 20-20-20, you still need at least 1/2 teaspoon per gallon to have any effect and even then, if you did catch the stomata as being receptive and such, the affect will be short lived compared to proper nutrition at the root zone. You're seeing what you expect to see and telling The Herd what you think they want to hear, not necessarily a direct affect of your actions.

You're just wrong. That's it. Plain & simple. The mix I used ended up coming to a little over 200 ppm. But you didn't even ask. Nor do you have a clue as to what nutes I'm using. Instead you quickly disreguard my findings as placebo. Guess what? I don't care. You're not gonna be convinced, because you see yourself as expert. And you may be. I am the last thing from an expert, as I am on my first grow. But what I am is observant. And I don't need to be told what I did or didn't see with my own 2 eyes. Keep telling people it's a load of crap though. There's a place for everyone here.

I am not getting this.... FNG shows up and starts handing out the slags..... Do a little research and you may find out who Uncle Ben really is...
