Potting, dividing,?new growth node ?, no roots what to do -Ric Chien Ya Lantern

[Skippersmom]

Two questions,
1) would you also give the potting media a long soak in the kelp magic before pottingthe plant in?

2) after mixing up a watering solution of the 'K-M', how long can it be kept for future use for additional waterings?

3) Can it be over done, as in applying too frequently? Difference between younger versus older plants?
Thank you !
