I've just started a Hydroponic Grow. I'm using CoCo Pete mixed with Perlite as Grow medium. 6 Plants, 3 in 18Litre Pots & 3 in 14Litre Pots. I also have a lot of Hydro Nutes, Bottles of the stuff! I manually Water the Plants, so Nute Solution is made fresh. I want to know, How often do I give my Plants Plain Water? And how often do I feed them Nute Solution? Also is 24 hours enough time to let Tap Water sit & let the Chlorine evaporate? It's a Hydro Grow so I assume you need to Feed regularly, like Feed-Water-Feed-Water-Feed etc. etc......
Feed them nutes everyday except for the last week of flower. As long as you don't over nute, you're good. Yes, 24 hours is enough for chlorine to evaporate in an open container with full oxygen availability. Not in something like a 2L bottle with a small spout.
