Slower growth in 4th month
I've noticed that after 4 months, my plants starting to grow slower than before.
I didn't change anything, so I assume it is now the time to add fertilizer?
2nd and 3rd month, I practically had to trim every week (plants almost doubled it size)
CO2 & Light are pretty much constant (except if you think the light deteriorated that much after four months)
What do you think?
