Sure!

I have two identical liquid test bottles, two vials.

When I fill both vials, and use one test liquid bottle for one vial, and the other test liquid bottle for the last vial, both vials filled with the same water source- they both show up exactly the color and hue.

I know that's not exactly the best test since they are both made by the same company. But I'm positive that its doing what it was intended to do. General hydroponics so I trust it.

Were you looking at Mr Droopy and thinking pH problems? My other plants seem fine, just extremely slow growth (which could be contributed to pH problems?)

I'm going to take a picture of the babies (except mr droopy) under flourescent lighting with the HPS off, so you can see what the coloration is like, and then upload them to this post.

thank you for your help!
