@synsfun...the photobucket picture was the only one i could find with the black blotches...NOT MY PLANT.

I just took pictures of my bell pepp problem: the first four pics. The last pic is of a snack tomato hybrid showing similar leaf tip issues, but no black blotches. WHAT COULD BE WRONG WITH THEM???? SOLUTIONS???

I unpotted one of the bell pepps and the roots looked great: white and not root-bound...no bugs in potting mix and all smelled fine. I've only watered deeply every 6 to 7 days when the pots felt very light-weight.

Again, I did find thrip bugs as mentioned in my first post....so not sure if they were carrying some type of virus/bacteria.

I am heart-broken because I've taken such care over the last 45 odd days. I've resolved that if my seedlings don't pan out, i'll just go buy a few plants at a garden store. THANKS FOR THE HELP IN ADVANCE.......
