will they be ok like this or am i headed for trouble
Ok, you deffinetly need a ph and a ppm meter, but under your circumstances (having RO) you can do without for a min. Your RO water should come out 6.0-6.5. The nutes your using have buffering solutions in them and will drop it depending on how much you put in. You gonna have to change your solution out a lot more than you would normally to keep control but You should be cool until you can afford one. But get a ph meter ASAP.
GL with the grow..I have a very similar setup so If you need help just ask. Later
I've grown several crops using Peter's 20-20-20 along with tap water. I almost never check the PH. They grow big, fast, and healthy.
White snoop, my r/o ph water is 8.1. I got a new r/o unit and the ph is really high. What does that mean? Did the water company change the ph level? My old r/o unit, the water came out 7.1. Funny.
You should be OK, I think...what he said. I find that if you use ROwater, once you mix in 3-part...you almost always get real close to 5.6-6.0 and I check mine every time... but if my ph meter broke and I was still using 3-part; I would trust it, until I got my PH meter..In closing the 3rd argument above was...GET a PH meter! LOL...lw
