"Im watering all 4 of these plants 2 or 3 times a day. Once with fertilized filtered water, then next time with just filtered water, then back to fertilized and so on."

Whats happening?
I would highly recommend watering your plants only once every 2-3 days......And give it just enough water to produce a slight amount (10 %) of run-off.
Fertilize every other time and just plain water in between......

Letting the top of the soil get completely dry before watering is ideal.

Peace and good luck:thumbsup:
