I find feeding veg friendly nutes until you're nearing the end of stretch helps and transition to full bloom nutes by about week 3 or 4 of flower. helps to keep them nice and green. Plants need nitrogen during flower as well, just go easy. Hope this helps somewhat

What is the ec of your runoff ?

Bit hard to be sure without pics, but I find that the stretch phase leads to very hungry plants for a few weeks, and even when upping the nute strength new tips appear a bit pale and yellowish, it's pretty normal.  As above I stick with veg nutes for up to 3 weeks into 12/12, and also temporarily raise EC by about 0.2-0.4.  Just be sure to flush the coco out after doing that.

Hey tough, it was way to high at 3.4-3.6 but flushed them last night and bit it down to 1.5 colour is coming back on them now and looking good just got slight nute burn from the high ec in the soil but should come back after the flush thanks hashy I left a pic it's in the link I can never get the photo to upload through here
