Very true. Thats why i told him to ease his way into 300 ppm slowly. Ive heard and seen so many bad grows from that moisture control crap. The good thing is that once the plant starts feeding and growing faster the plant usually snaps right out of it.They are starving because the roots are drowning... That moisture control retains water way longer than normal soil.. A little water goes a longgg way... Its better for outdoor plants in dry environment.. If you are going to use that stuff..let it get bone dry before watering again..there's enough food in that soil to have those little plants dark green.. The roots are drowning and can't absorb any of it..more foid- water will only compound the problem.
If I were you, I would get rid of those bottles and build a water only organic soil that you can use from start to finish. Either a super soil or a living organic soil that can be used over and over again. I'm into the living soil, it just needs periodic top dressing with amendments such as kelp meal, neem seed meal, worm castings... The simplest, cheapest, most natural way to grow with the best quality meds, period.@Alienwidow @Corso312 thanks, I'm not gonna use it anymore. I just ran out of that moisture advantage soil. I'm thinking about switching to Fox farms ocean forest or 100% perlite next time i order.
