Did you read the application instructions for superthrive? One drop per gallon. I took a dropper and a scale at my lab and figured out how many drops are in 1 mL and you gave ST at FORTY TIMES the recommended application rate. Nooooooes!!!

Read the flushing sticky at the top of the troubleshooting section and flush to get your soil cleared out and the runoff up to 6.7, then feed with 1/2 strength base fert only, NOTHING ELSE, and let the pots dry out significantly before watering again.

Mixing different media and all kinds of fertilizers causes problems. Just stick with the basics until you have a better sense of what the plants need. You should never use a supplement until you understand WHY you need it and HOW it works.
