When to add nutes?

Hey Everyone-

I've got my seedlings in DWC under 400 MH and they seem to be doing great. Right now they have 2 sets of real leaves and looks like the 3rd is developing.

When is the right time to start adding the nutes?

Thanks.

They are now seedlings and not germinating anymore. You can give them nutes now. Just give them half strength. Think about your nute relationship to your plants. The smaller the plant, the less amount of nutes. The bigger the plant, heavier amounts are needed. You want to be at 5 - 800 ppm right now. Good luck

Ok, great. My nutes arrived in the mail. What's the best way to measure the PPM?

With an EC meter. It's the only practical way actually.
