Ist time rooting success, please advise
I posted on Jan 05 that my 3-month old HT cutting had shown no growth. I am ecstatic because there is growth. In fact, within the last week it grew 3 inches! It is still in an old aquariun and there is lots of moisture. Occasionally I spray the leaves with a very weak solution of epsom salt. The medium is Coir which I think has no nutrient. Please advise me about the following:
1 When do I start to fertilize and what kind do I use.
2 What concentration should I use and how often.
All advice appreciated.
