Sea of blue my first grow

Starting this week and noticing light stress. With my viparspectra p2000 I’m at 17” inches and they are doing well. On my viparspectra p2500 I wasn’t raiding enough for the stretching and it was at about 15” I took it up to 18”. I’m taking my nutrients down I’m seeing ambers on my blue gelato and the tricomes are getting alittle cloudy I’d say two weeks till it makes the cut. I think I’m gonna let it grow till the 3 blue dreams are done, so I can have a nice bed time joint. probably two weeks also with the dreams I’m noticing a few ambers here and there with mostly clear heads. Hopefully two weeks will be prefect cloudy. I want to see how day these buds will get in the last two weeks
