Anyone know what this could be?

Been giving it the recommended amount of Nutes..all 3 plants are the same, one started to flower other two should be in a few days hopefully.. just don’t want them to die.. anything else just ask

We're going to need more info... Soil or Hydro? What type of soil and amendments or what hydro and what PH? What light source? How high above the canopy? What Nutes? How often are they fed? This yellowing and necrotic tissue is on 1 of the 3 or all 3?

They're not gonna die - don't worry. Get back to us w/details and someone here can def help.

Is that on the bottom of the plant? Could we get a pic of the whole plant please?

I'm also a dirt guy, unfortunately, but someone will be here that knows your setup and can help. If I had to guess, I'd agree with St Nick - something's too hot.

Did you wash AND condition the coco before you planted. Plagron cites this as necessary due to high sodium content in thier coco. You may need to flush and add cal mag to your grow. I cant find much out about thier fertilizers, but what i do know about coco is that cal mag levels are a concern.

Nutrient burn perhaps. I have had this issue but not to this extent, when growing in coco what i find that works best at least for me was to feed one or twice daily and make sure you get run off. At this point I would flush aggressively with ph'd water. Coco has a nasty habit of holding onto nutes if you dont water until runoff. Looks like they burned and are now in nute lock out.
