Personally I always assume micros and beneficial/ enzymes are necessary. Hard to hurt at those rates
Care to elaborate? Are you saying to mix maxi bloom, and cal-nit?No. Not really.
What do you mean by moot?~125 N, 40 P, 175 K, 150 Ca, 50 Mg, 60 S, 2.8 Fe and micros. A lot of this is moot when you use a high quality fulvic with chelated and complexed micros and your pH is in check.
I’ve been running 122 ppm of N, and my Sativa doms are displaying Slight N toxicity. Dark green leaves, and tips are doing the eagle claw. The males Sativas are having no issues with the N that high (which isn’t really that high), but the girls are not happy.Assuming everything else is in check, why not? What caused the N toxicity?
Hello. Can anyone tell me what is the recommended elemental ppm for K in coco? I see 170 ppm recommended, but was thinking that might be to high for coco. Anyone have any thoughts on this?
Ca equal to N with K being 2x Ca and Mg half Ca with P being half Mg has worked well for me pretty much start to finish. Targeting 100-120ppm NPlants will uptake way more K than they need, and if there's too much in the ferts, it will block Ca uptake. Your best bet is to find the sweet spot for the K:Ca ratio so not to over do the K. I want to reiterate though that using a branded blend, and relying on the numbers given on the label, you're almost certainly being lied to, so you'll never really know what your elemental ppm really is. IMHO, make all your own nutes or forget all about elemental ppm.
Fulvic acid is negatively charged and binds with positively charged elements like calcium, magnesium, sulfur, micro and trace elements, which is how chelation works. The deposit and processing determines whether it is free fulvic acid or bound. You can use unbound fulvic acid in hydroponics to chelate your exact nutrient profile or micro specifications or use bound fulvic acid to raise sap pH to resist pest and disease pressure and raise brix for higher TAC and terpenes.Are there sufficient calcium components in fluvic fractions to sufficiently drive calcium needs?
Right now I’m running a few Sativa dom hybrids, and they just don’t seem to like nutes in general lol! The elemental ppm value I’m running for them right now is N 100 ppm, P 50, K 151.25, Ca 111.25, Mg 59.75, S 75.25, Si 52. Some of the signs of N toxicity don’t seem to be reappearing on the new growth. I’m also using Maxi Bloom to hit those values because I can’t get my N low enough, and my Ca high enough with the 5-12-26. I just don’t think there are enough micros in the Maxi, and taking into account what Skybound says about the premix values, then not really even sure if they are what the calculator says they are.Ca equal to N with K being 2x Ca and Mg half Ca with P being half Mg has worked well for me pretty much start to finish. Targeting 100-120ppm N
Not exactly what I do now but that was a pretty fool proof for me.
