Question on fertilizers and rooting hormone in S/H
 

Hello everyone, i´d like some help with a doubt that´s been gnawing at me for some days

I started to use S/H for my plants, mainly due to the extremely dry weather i have so watering is less of a need, so far, growing in S/H are laelias, cattelyas, LC´s, Zygos, Cycnoches, Paphios, Phals, Coelogyne, Dens, and other ones i cant recall right now, and they all seem to be in good shape, save the coelogyne that hasn't grow any new roots but 2 new Pb´s.

Anyway, since here is fairly difficult to obtain PA and K-L-N, I use Hydrotron, and recently acquired some rooting liquid, composition as follows
250 ml total
N-P-K......................... 20%
Fe, Zn, Cu, Mn, Ca, S.... 3.50%
B1, B5, Niacin............... 3.50%
citocinins, giberelins, auxins .. 2430 ppm

Thing is, i wanna use it to water some of the ´chids, but according to Ray´s website calculator, taking in account the N-P-K thingie i should use aprox 1/2 tsp / gallon, but i´d like your opinion on this.

Besides, i acquired something called Bio-micron, which claims to be a liquid vegetal stimulant, seemed a good thing so i´d like to give it a try, it´s composition as follows
250ml total
Mn... 0.57%
B.... 0.192
Ca... 0.19
Mb ...0.007
Fe...0.71
Zn...0.25
Cu... 0.19
Mg...0.067
Giberelic acid .. 0.1
Indolbutiric acid .. 0.001
S.... 2.00
Aminoacids.. undetermined
the problem is that i don´t know what quantity to use on a gallon, and the guy at the store wasn´t of big help, so i´d really thank any light you could give on this!

Later i´ll post some pics of my plants, not all of them on S/H but pretty nevertheless.

Respect

about fertilizers
 

I thought so, but theres no indication of its use in regular plants, says 250ml/ha for floral plants, so no idea on how much for a gallon
