mixing GLA EI package
Hello I have a 55 gallon tank using pressurized co2 with a diffuser.
soil is dirt capped with gravel
I notice lately my plants arent doing so well after about 4 months now, they were growing well before, now not so much. I notice a little bit of BBA starting to crop up on the end of some leaves.
I bought the GLA Estimative Index package. I have a scale, I've been trying to get things right on those nurtient calc's. trying to calculate for a 500ml solution.
Calculator comes up with:
159g Plantex CSM + B/500ml @ 5ml every 2 - 4 days
254g KNO3/500ml @ 5ml every 2 - 4 days
39g KH2P04/500ml @ 5ml every 2 - 4 days
I have hard water so I haven't calculated for K2SO4
does this look correct?
If not, can you please guide me in the right direction?
I do 40-50% water changes every week.
