My very small grow:

This is by far the worst of the lot. Just transplanted 3 days ago. I'm guessing overwater or pH problem? pH of the runoff is 7.4-7.5 Growth has pretty much come to a halt since the transplant, as expected. The bottom leaf's tips on a couple plants are BRIGHT yellow, which has not worsened in the last two days (24 hours after transplant it happened).

I have not nuted yet, but i plan to start very soon, i think the slow growth has a lot to do with the lack of nutes (especially no N ?). Using plain old 3$ a bag potting soil (no nutes in it AFAIK), transplanted into 3.5 gal pots. Watering usually happens every 3 days, with discretion to the soil moisture. They've been watered once since the transplant.

Thanks in advance.

Correct ph for both soil runoff and your water should 6.2-6.8. i'm pretty sure that's your problem.

I'll flush em tonight, can i use vinegar to reduce the pH? I do have a pH pen, but no pH down. What's the best course of action?

Watered all four with 6.2 pH and 1/2 dose of 8-7-6 ll purpose liquid feed. Will update in a couple days. Time for some CS!

That sounds good....keep an eye and make sure the new growth comes in healthy looking.

good luck.
