... it's not that uncommon to see an auto turn out to be a photo, usually by error or bad breeding,... there are a lot of half-ass genetics out there!
... well, with no info about those 2 most important things, you're in a real bind,... such monitoring is mandatory with coco, or you end up with problems like this, and no means to determine what to do next,.. the problem is, if you have a toxicity issue (salt build up) and/or off pH, feeding more will make matters worse... if you're lucky, it's a simple lack-of issue and upping the feed will fix things,... But with no ppm and pH info, I can't offer you any solution other than a blind flushing and rebooting the feed schedule,... in coco, you shouldn't flush with water alone, or you'll screw up the CEC balance in there, if that not TARFU already,... recommendations are to use RO/Di water, with 150ppm of Ca-Mg, plus another 150ppm of nutes, pH to 6.0 and pour through until the run off is at or near input readings,... but again with no TDS/EC meter, this becomes a risky gamble to do blindly,... sorry mate, no way around it, you need the right gear to run coco,....
