Has anybody noticed the difference between what is on the back of a GH container, grow, micro, or bloom. compaired to the chart from there web page ?
Tell me why, just for instance,,, the gro on the container suggests 15 ml per gal. for aggressive growth, compared to 1 ml on early, mid, or late bloom on a flora series simple drain to waste chart. simple question ? or is 1 tsp not = to 5 ml ?
I have also noticed this... the only thing I can think of.. is you would follow the back of the bottle if you were using it as an additive to a different kind of food (although Im not sure why you would use only one part of a 3 part system?) So in other words.. you can use "grow" as a veg booster along side other nutes.. or "bloom" as a bloom booster etc... If you are using all 3 parts.. stick with the feeding chart for now.. It will keep your plants happy and healthy with a useable end result. Just FYI.. most cannabis strains can handle 2-3 times more food when using a B-1 vitamin supplement (B-52, Vitamax, etc) in OPTIMUM conditions (High Co2, controlled temp/humidity, good lighting etc.). The chart they give you is more of a guidline to get you started... In time you will get to know your strain and how much you can push it! My final week of feeding consists of 10G, 20M, and 30B per gallon.. It ramps up week over week to get to that point.. but it just goes to show how much more food these plants can take! Cheers!
Thanks for the reply Jay, the below isn't just for you, but hoping some more answers come along for my original ?
because a couple years ago, if you look, GH feeding scheddule use to use a lot of grow, up to 5 ml for agressive,that was the old light green schedule, now with the blue schedule that came out last year, its mostly 1 ml per gal. so,,,,,,,,,, why that change ?
I took a couple pictures last night to throw out here. you can see nute burn on the Great Whites, at 5 weeks of 12 .
ok, hope Im not making a mess of this simple question.

Your medium:
.7) Specific brand and type of soil, (coco, peat based soilless...) and anything you've added to it. (vermiculite, perlite, worm castings...)premier peat moss 2.2 plus 3 gal vermiculite, 3 gal perlite and about 10 lbs of worm castings mixied with a veg mix of nuts, weak mix.
.8) Size of container. 3 gal. plasitic
.9) Did you use peat pucks (or similar) to root clones or germinate seedlings? clone in cubes works great

13) Specific brand and N-P-K ratio for each bottle. List dosages (quantity per gallon) and current feeding schedule. GH 3 part flora series simple drain to waste. this is the ?
14) How often are you watering between feedings, and how much per watering? about every 2 days of 1/2 gal per pot, depends on how old, you know.
15) Any additives or tea's? (Superthrive, CalMag, molasses, Mother's Earth...) just GH 3 parts with liquid kool bloom and flora kleen about once a couple weeks, give or take on how plant is acting
16) Are your ph levels stable, or do they fluctuate? nope damn stable, even with spring crop planting in the spring around here.

25) Is this an autoflower strain? whats autoflower. lol
Honetly man.. I think the only people who could answer this question with any kind of accuracy would be the folks at GH... They probably have a team of scientists constantly testing different mixtures of food to see what has the best results at different stages of plant growth.. My guess would be that if they changed the feeding schedule a few years ago.. it was probably because their own research has been more finely tuned. I also know that since medicinal use came in a few years back.. many hydro food companies have been tailoring their formulas for cannabis (which are quite different from house plants). I think they just realized that the "house plant crowd" are NOT the ones buying their products.. and now that its actually legal to test for medical purposes.. many hydro food companies are taking advantage and tailoring their formulas specifically for cannabis.. Thats my best guess.. but maybe shoot them an email and get back to us just to be sure! lol
