Help! Use of fulvic acid!

[egz91]

Hi guys,
Yesterday i fed my plants with ghe nutes 3 part micro grow and bloom at a dosage of about 6 to 7 ml each per 8 litres of water but i added also fulvic acid to maximize the uptake of plant and give the plant all the pros that fulvic acid has on her.
Now i ended up with what i think is actually the start of nute burn cause some tips of the semi new leaves are starting to yellow a little, i gave fulvic also to a pretty small plant about 2 weeks old.
Help...have i used fulvic the wrong way?

Growing in a 80cmx80cmx160cm grow tend with 400w mh lamp and a 150w led for support!!!

Grow with soil of biocanna: little prefert soil but now the bigger plants are about 1 month old!!

Welcome. As your media contains peat, which has humic and fulvic acid, why are you adding more? You may have lowered your pH a bunch, but I've never used it, so hopefully others will kick in.
You can get slow release fulvic and humic acids in a substance called Leonardite. It's found in coal beds. GH used to sell it in solid form called Diamond Black(I think). Now they sell it in liquid form by the name of Diamond Nectar.

thanks for quick reply...so now what do i have to do? flush immediatly or wait for soil to dry out before flushing? or maybe just wait...i watered with nutes as i sad yesterday.

If you think it's burning, flush a bit with 1/8-1/4 strength pH adjusted nutes. The sooner you stop the burn, the better.

I'd use 1/4-1/8 strength nutes. I like to flush with an ionic mixture, and RO has no ions.

ok i'll add micro grow and bloom at 1/8 strength. some enzymes too? i also have top crop microvita bacterias?

Just the nutes would be fine.

I foliar on Ful-power (fulvic acid), I never add to soil. The plant wild adsorb all that goodness thru the leaves with a foliar and you don't have to worry about the soil issue or interaction with your fertilizers.
