Greening leaves

I recently flushed and just put my first coco grow to flower. week 1 and they are starting to turn light green.
My ph is 5.5 My nutes are coco A and coco B from the House& garden line. I am growing in mixture of coco coir and perlite. I use the text book nutes following the feeding chart recommendations. I can't tell if I need more nitrogen or if the solution is to strong.
I could really use some extra help all advice is welcome here is some pictures

Did you use nutrient solution in your flush or just plain water? They say not to use straight water because it messes with the buffering capacity of coco, although I have seen many people do this with no I'll effect. What ec are you feeding her?

That light green growth is just new growth. Your plants are doing fine. They will turn darker in time. 5.5ph in soil? You might want to get that to 6.5 in coco. What are your ppms? You should be around 1000ppm on your first week of flower.

this is my thoughts too, i sometimes see plants turn pale green almost yellow towards the middle of the leaves during early flower
this is when the plants are having their biggest growth spurt, i believe the plant builds the leaves first then greens them up later naturally
i like to judge them not just by colour but also by the texture of the leaves if they still look vibrant and lush, as opposed to the dry dehydrated look
i think they are fine i never add anymore food when they do the yellow/green thing during the start of flower they sort themselves out
this Jamaican grape would do it all the time and would sort itself out couple of weeks later







peace

i like to start by saying thanks all for the advice
I flushed with plain water that was 5.6 ph
I don't have a ppm meter. I did a test plant run without one,it worked out fine,is that a mandatory investment for "coco/soiless mediums" growing in numbers ????
I have grown awesome soil plants and had them start to yellow like this and work themselves out but this my first coco grow needed the help agin thanks

Many people don't use them. Although when I run into problems it is the first thing I reach for. The meter really reveals a lot about your feeding regiment. If used properly it is really the most useful tool one can possess, in my opinion.
