is my fert enough?

[David Moses Heng]

Curently, my i am dosing my 422 with 7 tml of aqua lush grow macro and 4 mls of aqua lush micro grow daily. I'm running it with a sump. Question here is is the amount of liquid fert enough? the plants are doing so so. Co2 dose is 6bps with lights on from 1400 - 1700 then 1900 - 2300 hours again. CO2 is on one hour before each lighting cycle kicks in. plants start to bubble once light comes on. can anyone advise?

how many ppm is 7ml macro?

sorry buyt i don't get what you mean?

That is the problem with liquid fert, slightly hard to find the ppm

Anyway, for high light and 20-30ppm of CO2, Typicaly the fert ppm target are:
NO3: 5-30ppm
K+: 10-30ppm
P04: 1-2ppm
Fe: 0.2-0.5ppm

1ppm = 1mg/l

Thus it is easier to does the pure fert from lushgrow, KNO3 and KH2PO4.

Bro Altum, not sure if you have this site. Hope its useful to you.


Anyway, Lushgro Micro is meant for hydrophonics, so i think should be very concentrated. Its instruction is 10drops/100l/week. For you shuld be about 45 drops/week. I think Micro is very concentrated. Not sure if your 4ml daily is too much?

You may be meaning Lushgro Aqua (LGA) and Lushgro Micro (LGM)?
There's a discussion in the past at http://www.aquaticquotient.com/forum...ead.php?t=5976
A calcultor to compute the dosage is in there too. Note that in these 2 fertilisers, Calcium and Phosphorus are not included.
Depending on your plants requirements, you can dose LGM and LGA with K2SO4 / KNO3 and KH2PO4.

I use this calculator for my plant tanks.
