What were your runoff ph's? For all those waterings. Are you in the danger zone? Im not familiar with liquid tests so I dont know what the colors correspond to.

Also, dont assume your soil is not buffering at all just because your ph was the same going out as it was going in. Could be your soil was very near to that ph already!

Oh, and youll be a lucky gardener that has all your plants on the exact same watering schedule. I do a constant grow, and its a headache trying to keep track of everyone!
The runoff pH when it was low was in the 4-5 range. The runoff is now higher.. in fact one of the plants I watered today actually had a higher runoff than the water I gave it. I'm just going to water them with consistently pHed water from now on and alternate, pHed water, nutes (with slightly higher pH) and see what happens. One problem is that my water has way too much chlorine, I guess I will have to start letting it sit out over a night or two then lower its pH before watering. I think the high chlorine content of my tap is what caused the initial yellow of the leaf tips. The foliar feedings dont seem to be hurting them, the leaves look a little bit more normal around the edges since I started. I am keeping the light backed off for now, it is not enough light and they are stretching and barely growing, but my 400w should be showing up fairly soon and I will be able to keep that a fair enough distance from the canopy while still getting enough lumens to the plants. I'm attaching another picture.. but the camera never seems to show the problems, it makes them look much nicer than they really do. Most of the plants (except for one) have very pale yellowish leaves and look like they are exhibiting the early stages of chlorosis. I know, they are small for a lil over a month old, but for all the problems I have, I am surpised they are even still alive
