Depending on your substrate is a factor. If in a inert substrate then day 7. If in soil can be week 3 or later. The mix has a lot to do with when and how much etc.

Water and nutrientsI water every other day. So far I have been using nutrients to bring my water up to the proper EC (ppm). It is always a VERY small amount (1/2 tsp). I haven't noticed any signs of toxicity but I wanted to hear your opinion of my approach and changes that I could/should makeGDP- Second attempt
