phosphorus?

Is this a phosphorus issue?

Growing Coco 5.8 ph watering twice a day. Growing with two other plants showing zero issues.

My eyes are very fuzzy today, AJ, so I can't make out much detail...
You might have better luck if I moved this over to the infirmary, with your permission.

Yes please move it over.

I would say that yes it looks to be early P def. P demand rises as the plant moves more into flowering. Give me a little more info please.

I agree with Ren Red.

Moved to infirmary, but @Heavily Medicated was already on the case.

:smoking: AJ' what's good? Can you get us a closer pic of the 4th leaf above? I think I see mini-spotting, which is classic Ca defc.,... there's some tip claw, hinting at older-(?) minor N-tox',... and the over-all yellowing could be early P defc., or linked to the Ca and maybe Mg early defc.'s... But, I think the ppm's are too high for twice a day, and you may be getting some type of lock-out from uptake issues; too much of some will interfere with the uptake of others, so even if it's there, it's not getting in well... This is drain to waste, right? My coco-nuts tell me about 1.5-1.7 EC /appx. 750-850ppm at this stage, with about 20% run-off,... Can you take an in-pot pH with a good probe? If not, next round, feed lighter, and test the run-off collected from a clean saucer for pH and ppm's,... if it's off, and/or ppm's are300+ higher than going in, there's some cumulative build-up going in there, not quite a burning issue yet, but heading there,...
