So i just checked my ph and it's about 7.

I've heard lime can lower the pH, anybody know how much I should use.

no, no, lime will raise the ph ...- I bet as it dries out it will go back down. What kind of soil are you using? Tap water?

How did you check the ph?

the problem is insufficient light.. my 14 plants are 2 1/2 weeks old with 5+ nodes under 800 watts 20/4 - and I even had ph problems for a week. Best thing you could do right now is buy a decent light.

btw I can see they are already wet - you need to let them dry out before trying to adjust the ph or you are going to have more problems.

put yoru 4' lights like the 18" one is, horizontal and 2-4" away from the tops of the leaves.

the 18" lights are actually weaker towards the ends. So most of the light is coming out of the center of the bulb... where those two plants that are biggest are... thats my only idea
 
There are a number of reasons for what your plants for stunt growth in the beginning...

It may be due to your lighting system...or nutrients, or ph

You said that your ph is at 7 - which is neutral

Soil and water ph levels are exceptionally important. Ph should be at 6.5

Lime amendments will raise ph as csharper mentioned and lower acidity, but too much lime can burn roots and make nutrients unavailable.

Fine Dolomite Lime has a neutral ph of 7 and cannot go beyond 7.

A proper fertilizer regimen and regular leaching helps flush away toxic salts.


Lowering soil pH : (to make it more acidic)
If your soil needs to be more acidic, sawdust, composted leaves, wood chips, cottonseed meal, leaf mold and especially peat moss, will lower the soil pH.
