Leaves look like copper

I am trying to figure out what the hell caused this. It was top most leaf, happened rapidly (overnight), using strong LED's, feeding around 1100 PPM, almost 3 weeks into flower, skywalker kush strain from seed.

This look like heat stress or ph imbalance..

I will check the runoff tomorrow. It is in coir, and have been feeding higher PH because runoff was so low. It is also the highest tops, but hand does not feel to warm, holding there for a minute.

I found out from a seed strain review site, that skywalker kush does not do well with under or over feeding. Feeding now, and will check runoff shortly.

mag def maybe, coco is notorious for this.

letting the medium dry too much can also cause issues ph & ec

get back with runoff ph & ec numbers.

They need to be flushed. 3 of 7 were very high. Will feed 400 PPM or .8 EC for a couple of days, with some florakleen. I should really check once a week or so.

My PPM meter is 500 PPM 10 1 EC. Was feeding between 1000 and 1200 PPM. Tonight fed 1350 PPM, and runoff on that plant was 2060 PPM.

The PH was too high also. I usually have problems with low PH runoff. When I checked a couple of weeks ago, was feeding 6.0, and runoff was under 5.5, so have been feeding higher PH, and lowering each feeding. Fed 6.2 tonight, and runoff was an average of 6.5, so will lower, and check until it is stable.

Thanks for the advice!!
