hello I have been foxfarm ocean forest and everything had been going well but I have been seeing this start to happen
i have never used soil before only bubble buckets any information would be every helpful I have been using RO water at ph 8 to water then as well think that is correct ph …i hope
Welcome to the forum
Not sure about a deficiency that is some nutrient rich dirt.
However RO water is stripped of beneficial minerals and trace elements
So it could be the start of a cal-mag issue
Here is a chart
It kinda looks like nute burn to me but the plant looks well established and if you have not been feeding and have been watering as needed I would not think that it is nute burn
But I am a newb lets tag in some veterans and get you some direction

Ph 8.0 is way too high for growing mj. Soil is 6.5 after nutes and 5.8 with hydro. This can produce a lockout that can appear as an excess too in some media.

@Myfriendis410 is on point ph is way high at 8
Ro water rends to have a higher ph
You should be adjust ph of water at 6.3 -6.8 with soil ph target of 6.5 @Growit @Firstgrow thats what is causing the color issues
Good call @Myfriendis410

Yes it will anything about 6.8 can cause issues FYI
Soil ph is most important
You can obtain that with runoff of by doing a slurry test
But ph your water or nutes to same place each time helps as well
