I'm sorry @Auggie, but if he follows your advice his plant will dieI looked close at the pix's and read your brief.
I did not read replies ... this is my take:
Over watering. You're keeping the roots soaked, drowned. They can't take up nutes that way and are showing signs of lock out. The clawing in pictures three thru five show that.
Water when the medium gets dry. If it takes a week to dry then so be it.
Nute to 800 ppm when you do water, and ph to 6.0 or there abouts.
And, since you're a new grower, consider choosing an easier genetic to grow next time.
Someone that just got their drivers license should not be driving a Ferrari.
Did you not read the part where he's in COCO, and needs to water everyday
And what plant are you growing that you need to PH at 6!!!!
And the last comment...well...The same could be said for people giving advice
