i am indeed. no room or money for aeroponics. which is what i want...
Even so, plants in soil easier take up nute's with a ph of 6.5. I'll bet that after you add your veg' feed your ph is at 7.5, could be even higher. My tap water sometimes comes out at 8, and that's just standard tap water. Mostly it comes out around 7-7.5. Soil is fine really up to a ph of 7. Plants just prefer 6.5 in soil.
I wouldn't bother with aeroponics. I've never heard of a successful grow using this method. The spray nozzles get blocked up with the salts from the nute's, and within a couple of hours your whole crop is dead. There is a way, by using high velocity, the nozzle is spinning so fast that it can't get blocked up.
If I were you, I'd try hydro first. Then move on to dwc or nft.
