Step Right Up and Diagnose Me!!!

Hello, I'm a farely new grower and im having some problems with my plant, as you can tell. The problem all started when i fed the plants with 6-12-6 miracle grow plant food when they were barely a month old. Now at about a month and a half they are beginning to look better, but still not good. After noticing that i nuke burned my plant i flushed it once to help get rid of the extra fertilizer and have been watering the plant with water and diluted superthrive. I held back on flushing it again, and am waiting for some real results, the newer leaves are beginning to look more normal but still have burned tips. The soil is regular planting soil with a ph of about 6.8. It's a bit damp since watering today and the temp inside is about 78 degrees. I also bought some 5-1-1 fish emulsion but i feel its not the right time to use it yet. If anyone has any questions or suggestions it would be greatly appreciated. Like i said i need some help so please get back to me. Thanks again:rastasmoke:

Either flush again or transplant into new soil.

You are correct it is not yet time to use the fish stuff.
What was the mix ratio you used of superthrive?
ST has a LOT of nitrogen in it, and the shape of those leaves indicates N overdose.
WH is right, a transplant into nice fresh soil would do wonders for that plant. Allow it to get a bit on the dry side and it shoudl slide right out of the pot without too much disturbance to the roots.
