I seem to be missing something with my setup. Im using pressurized co2, EI dosing, about 2wpg and a 4 hr burst of 4wpg. I do weekly water changes and still the plants in the tank look sort of burnt. They are not bright green and healthy looking like Tom’s tank or most other tanks that you see. What could the cause of this? A lot of the plants look like the edges of the leaves are burnt, they are sort of brown and not very healthy looking. Any ideas guys?
Try to lower the intensity of the burst as well as the duration.
eg. 3wpg burst for 2 hours.
I've heard of people who do 4 + 2 (burst) + 4 hours light but I'd rather go with the constant 2wpg.
Make sure your EI dosing is correct. (calculations and such)
About 1 1/2 months back, I thought I was dosing correctly when I was actually under-dosing. All my plants suffered.
I'm totally convinced by the EI thread that dosing more is better than dosing less. So now, I dose a bit more than what I calculated and my plants have been growing very well.
I'm assuming the usual drop checker/CO2 is up and running as it sounds like a macro deficiency vs too much light.
Hope this helps =)
