This seeding has always seemed to have a yellowing. I thought may be too much water but cut it back and it still continues with yellowing. it is in potting soil, transplanted to coco with moderate amounts of calmat and minimum amounts of fertilizer. Any ideas?

The yellowing started before transplanting 10 days ago. I am feeding Dekine at 1/2 rate.

I am not familiar with that fertilizer but your new growth looks good from what I can see. As long as is not progressively getting worse you might be ok. How has its growth been? Also looks like a little nute burn on a couple leaves.

Which Dekine nutes are you using, how much exactly are you giving, what is the ph of the nute mix before giving to plants, how much water/nutes are you giving at one time, how often?

I have to agree with possible light stress due to the cupping leaves.

@Photooz temp is good what is you light distance?

14

The distance was 2 ft, I have turned the light down and gone to 3ft.I was at 7400 lux and now have it at 6900

Maybe water only for a minute, also I see water on your leaves. If you are Foliar feeding I would do at lights off, or maybe a couple hours before lights on to allow your leaves to dry before lights on.

Thanks for your reply I think I’ve zeroed in on too much light is the culprit. The water on the leaves was just a mistake it was corrected right after I saw the image. Thanks again for your time

Phosphorus deficiency Brodie ph to high for the plant to absorb phosphorus, in coco ph it to 5.8 to 5.9 no higher, in soil 6.5 to 6.8 no higher
