Fulvic and humic acids- when to use?

Hello all, I was given samples of both fulvic and humic acids by my local purveyor of grow goodies, and I was wondering, when's the time to start using them? Do they benefit more/less/the same in early veg/late veg/early flowering/late flowering, what not? Thanks all!

I've been using Fulvic acid for over 15 years on the farm and always on this crop. Fulvic helps move nutes around in the plant. On this crop, I use it weekly as a light foliar spray with some lite nutes and I also mix it with my EWC Tea which I use weekly in the soil. I would use it up to just a few weeks before cutting. Can't see it doing much good the last week or so. More is not better. I stopped using Humic altogether. I have some pre-mixed in my soil and that seems to be enough. After almost 2 decades of experience using both products, Fulvic is the ticket IMO.

IMO Fulvic is better then Humic.

you can go on ebay and get a lb. of 70% Fulvic Acid and mix your own solution $19... they have humic acid, kelp, and myco beasties also... It's alot cheaper and goes farther when you mix your own

Fulvic Acid

I use humboldt humic and fulvic (hum-bolt, flavorful), and I use it every watering except the last two weeks of flowering.

I'm using Liquid Karma for the first time (playing it by ear) and thus far am seeing amazing results. I began feeding it in low dose (1/2 tsp per gallon), every watering to some very stressed, multi-symptomatic plants on day 31 veg. Today (day 37) they all look amazing and are exploding with growth. This may not be the conventional application for all I know, but so far it has yielded very positive results in my limited observation.

Madd Farmer's for this crop. The bulk product for the farm I don't think has a brand name.

I am open to any suggestions from users of Fulvic as to a "brand" name that they think is better then Madd Farmers brand fulvic acid

can someone vouch for their fulvic acid, what i have now is GH diamond nectar but it's made using potassium hydroxide and phosphoric acid so i want something less chemical, if your fulvic acid is biologically processed and you have had good results let me know, if it's got any K and P ratio it's probably more chemical crud i don't want

im interested in this, dont use it atm - i already use citric acid to bring my 8+ pH water down and was thinking of using fulvic instead.

any pointers on dosage etc would be good. im in UK so the brands would be different here.

thanks
