Did I burn them or is it PH?

[Jadian21]

I've got some little (hopefully) ladies from various seeds that are about 2 weeks into an 18/6 cycle under a 250 watt CFL.

I gave them a splash of Liquid Karma with two waterings and had some lower leaves turn yellow/brown and I pulled them off because they would have fallen off in a few days anyway.

So I figured I might have burned them by adding the Liquid Karma early (even though it says you can use it from germination-flower). But my last few waterings have been just water (Which I have been PH balancing only this past week, bringing the PH up from about 6 to about 7.5.)

So basically I'm trying to figure out if I'm having a problem with the Karma I added or if it sounds like I'm just not hitting the right PH, they don't seem to grow too fast and bottom leaves turn yellow and die as more leaves form.

Wish I could do this a little more justice with some pictures, I'll see if I can borrow a camera.

Most the time its paranoia but a pic would be the only way to half understand yur sitch. Liquid karma is a good product if your not using a hydro res. Also dont ness. blame products cause I used to blame products when it was about other issues, Ive also biased on a few strains cause I never got them under control so I say I hate them

Isn't a Ph of 7.5 to high?

[Jadian21]

I guess I didn't really explain the situation well enough or ask what I was trying to get answered.

First of all, to anyone who uses Liquid Karma, when have they started adding the Karma and have they had any problems using it in the first 3 weeks?

Secondly, I think a PH of 7.5 is good because the run-off tests at about 6-6.5. I think the fact I started the seeds in rockwool and didn't balance the PH for a little while made my soil a little acidic.

Thirdly, I think I was overwatering. The first soil I had didn't drain very well and I think the plants were over-watered for about a week and a half to two weeks when they were first in the dirt. Since then I've mixed that soil about 50/50 with a heavily aerated grow medium.

I split about a gallon of Reverse Osmosis ph balanced water between 4 almost a month old (but small and not too healthy) plants that I've had this current problem with, and 5 sprouts that are about a week old and I haven't had any problems with yet. The first 4 were kind of just a trial run for the next batch anyway, but I'd still like to do the best I can with them, they have a lot of character at this point, kind of like the retarded kid that everyone was friends with in high school.


So which of those three would be most likely to slow growth and yellow/brown leaves? I dunno from what it sounds like it could be any of them and I know I'm just guessing, and until I get pictures probably all you guys can do is guess, but what the hey I'm trying.
