[ UNDIAGNOSED PLANT VIRUS??? ]

I picked up a gg4 clone 2 months ago which I vegged up to a mom plant and recently took this cut off of. Both the mom and this clone have had this nutrient looking tip burn on the leaves. The mom was fed very little under 600 ppms of remo nutrients veg and similar with this clone. The clone is in coco and it has no precharge so I’m confident it’s not nutrient burn. I also have 6 different strains in the same room under the same lights getting fed the same nutrients and they are all healthy. The plants get a decent run off each time they are fed also.

It's obviously got nute burn....that tiny plant doesn't need anywhere near 600 ppm. The leaves that are burned in the middle are weird though. I doubt it's a virus, looks like something physical. I'd check the coco runoff, sometimes you get a batch with crazy numbers even today.

the mom was around 2 1/2 feet with the same problem, and other clones that size getting fed the same are very happy
