They both seem to be PK boosters. So I would say there would be little point in doing this.
This is only my opinion. But basic experience has told me that any growing product that has cartoon characters on the bottle or packet aren't really all that. After a couple of years of using Cartoon based products, I discovered that a good quality Tomato feed and a basic compost mix was all you actually needed.
Tell us about your grow. What lights are you using? What medium are you using? What else are you feeding them?
you want the soil to be wet untill it drys to a depth of 1 finger nuckle, well thats what i do.
my 250 takes a while to do this, 400 and 600 are much faster.
you have moist soil by the sounds of it.
what soil mixture are you using? also, a pic would help too to guage the ratio of perlite/vamiculite or whatever you have used to go with your soil
Maybe I don't know...but I feed em when the pot is light, I don't know if it's good or bad but they seem OKMuch better looking soil than most
Maybe those cloth pots are making it hard to judge wateringneeds?
