...now all my reds are off and I've had to flatten the image to convert to CMYK so have lost all my adjustment layers.
should I have worked in CMYK from the off?
and how can I just adjust my reds?

yeah I hate that... especially since there are a lot of photoshop steps that you can only do in RGB

Adjustment layers are colorspace dependent. This is why you are losing them. The color range of CMYK is much smaller than RGB, especially in the reds and greens. Get used to it, and design accordingly.

Why do you still need layers in CMYK? I never convert to CMYK until I'm ready to flatten.

do the conversion once your rgb file is finished and the work validated by client?
then flatten it and convert it to a cmyk profile .

Yeah, uh... losing colors through conversion is like basic basic basic design knowledge. RGB and CMYK are totally different processes. RGB is achieved by shining light through colors (adding). CMYK is achieved by taking light away (subtracting). Basically, this means CMYK is always going to be duller than RGB, so your probably stuck with what you got...

Light / Four tints...hmm

RGB looks great on screen because a screen is RGB. When you switch to CMYK, the screen can't show CMYK, so it switches to a duller looking screen image when converting the file. What prints out will still be bright as the ink can achieve. Its just the screen version that looked unreasonably bright in RGB and now artificially dulled down in CMYK.
Always work in RGB though, and always keep an RGB layered master file. Time to start exploring those conversion profiles to push the relative vibrancies as far as you can without stepping the tonal range.

use 'view> proof colour' in RGB to see how the CMYK is coming out and adjust accordingly.
View > Gamut Warning is helpful as well.

Always keep the master RGB file, you never know when you are going to need to go back to the beginning. ALWAYS keep a master file with the layers. It's pretty simple to do.
When you convert to CMYK there's no reason you can't adjust it further. Many times I'll convert, flatten everything but the sky layer and adjust that as good as possible (won't ever be as good as RGB, but you can often times get it close).
It sucks, honestly, especially when a simple ink jet can print from the RGB file and look amazing.

just outta curiosity...
you are converting using a profile via [EDIT>CONVERT TO PROFILE]... ?
there is a checkbox in the dialogue to flatten/retain layers.
converting via [IMAGE>MODE] will often make the rgb-cmyk shift much worse.

always, always work for your final output from the beginning.

Rgb to cmyk is not nearly as painful as working with log to lin conversions when studios we work with don't use the correct luts.
