 Re: root tabs???
With 3wpg and CO2 I think you are going to need water column dosing. That's high light. Are your plants fast growers? I'm not sure the root tabs can provide enough ferts quickly enough for high light. If you have a nutritious substrate that is already releasing high levels of nutrients you could be fine.
Plants need CO2 + light + macros (potassium, nitrogen, phosphorus) + micros (trace minerals like what flourish provides). You need all three. With high light you need more of all others. People have said it's like the light is the gas pedal. If you increase the light you will need to increase all others. The growth will increase because of the light. Without other nutrients your plants will show deficiencies and begin to starve.
If you had lower light I'd say check your root tabs to make sure that they have all the micros and macros and you're fine. |
