why are my plants not responding to fert dosing
so i got pps-pro pack from one of the members here about a week ago. i used to dose aqueon plant food before and the plants used to bubble all the time when co2 was running. i started dosing pps-pro at night before bed, 1ml/10gal so i was doing 3ml of micro/maco.that wasnt doing much so i uped the dose, didnt work either, then i moved it to before lights on. dint work either. i have dosed 2 days 5ml (thats almost 2ml/10g). there is maybe 1 plant bubbling or 2 but thats all. i should mention that i changed the diffusing method, i went from piece of chopstick in the tubing to a ladder, im assuming there is more co2 in the water now since this looks to be a more efficient method. is there a reason why the plants are not bubbling like before, should i not worry? i was thinking of dosing plant food again tomorrow to see what happens, what do you guys think?
