Plants look nice my friend. What's the problem with your meter? I'd guess that it's more accurate than the drops. Have you calibrated it yet?
The drops are VERY accurate. The meter is dependent upon certain type of metal on the ends having continued conductivity. Unless you clean them after EVERYTIME you stick them in the soil, they rust and don't really work anymore.
Now I use both myself. But the guy i purchased my clones from originally, SWEARS that the soil probe pH meters are garbage. I guess the way he sees it, if you properly pH your water EACH time, you shouldn't have soil pH issues. But if you DO, that you'd know by pHing your runoff.
I'd suggest you just filter the soil out of the runoff water (coffee filter or something) and test it with the drops.
::shrugs:: But I honestly know very little on the topic, i'm simply passing on an opinion that may or may not be shared by me.
btw, wat do u think of some Lsting 1 week into flower?
