When using fertilizers can you mix different ones if your PPMS are correct ? I've heard you can as long as PPMS and PH are ok. I hear things like "use 25% or 50% strength" all the time. But I think if the PPMS are all tht matter (something like 1600 veg. and 1000 flower?) then I'll get a good meter and do it this way.
Also I was thinking about using small river rocks as opposed to hydroton. They're FREE first of all. smooth. and even pretty! . Only issue might be the weight inside the net pots..... but to my way of thinking they might provide trace minerals because the river I'm getting them from will provide several types of rock (slate qurtz etc....).
Any thoughts ?
