Any suggestions on the yellowing first leaves issue #Day19? Is that a Cal or Mag def ? Been watering with tap water left for 24h. Would RO water be better ? Does feeding with RO water on the entire life cycle involve to add more nuts ? I currently have only AN micro/grow/bloom.Tx

Good morning I think it's a bit early to tell for sure. Don't trust those bottom single finger leaves, they usually die off eventually similar to the cotyledons. The top of the plant looks healthy. But i have come to believe in adding a calmag supplement into all of my grows...i used to have a lot of problems before i started using it. So here in the next couple weeks i would pick up the fox farm calmag and start using .25-1tsp per gallon.

@Experimentgreen thanks buddy, I already ordered some CalMag and B-52 from AN, unfortunately fox fam isn t available in my country So does the CalMag need to be applied for the entire cycle? Or just in need? From time to time ? More specific ? =D. Also thinking to get some 6.0-6.5 Kangen Water from a buddy of mine who spent like 2500Eur on that machine, and see how it reacts, teoretically it should thrive
