Hello all this will be my first grow ever I have a 4x4 VIVOSUN all my girls are auto growing in 3gal fabric pots. Today I noticed some color changes and wanted to know if I need to change some things. I’ve been using ph water at 6.0 to 6.5 and I’m growing in ffof. My soil ph is at 7.0 to 7.1 we are at week 2 with these girls and I’m about to introduce nuts or should I? Please advise and help is greatly appreciated

Target 6.3 to 6.8.
You won’t have to feed for ~6 weeks from your last transplant if growing in Ocean Forest. Monitor runoff PPM and begin feeding when PPM dips below 1,000. Maintain that 1,000 PPM throughout the grow.
I see no issues with coloration.

Welcome to the forum. Glad you are here. Your plants look amazing for 2 weeks old.
As @MidwestGuy said, your soil came precharged with nutrients. The only way to know when those get depleted is to check the runoff (the water that comes out the bottom when you water the plant) You will need to water it enough to get about 20% of what goes in, comes out the bottom. You’ll need a good tester that checks either ppm or ES if you don’t already have one.

I am an organic nooby grower and am using Fox Farms soil and recharger for my grow.
As many have said the OF you are using has nutrients for a while and none are needed. Some are recommending changing to a water to drain and check PH and EC and adjust.
From reviewing your numbers your PH is high for an organic grow. The main Happy Farms product I use for the soil is Happy frog and it is PH’d close enough to 6.3 to just ph your nutrient solution. Since you are out of the PH range for oganic grows I am unsure if you can reset the system.
PH is not a progressive scale. ph7 is not 2 times ph6 it is 10 times ph 6. For an organic control of 6.3 the reading 7.2 is very high and some of the nutrients will not be recharged by the organic nature of the soil properly at this PH.
I think you are going to have to add nutes and ignore the 4-6 weeks of energy the bag came with unless the ph level can be restored.
Perhaps someone could advise on a strategy to lower the PH and restart the organic aspect
