potassium deficiency perhaps?

@ms48130 Too much potassium looks just like not enough. Look at all of the salt build-up on the outside of your pot. That indicates to me you have a salt build up and need to flush. First rinse off the outside of the pot the best you can then do a nutrient flush with 50% strenght nutrients to 50% run-off PH 6.4.

maybe I'm getting the hang of this... I was thinking same thing (flush) - just bought some GH FloraKleen (arriving Tuesday, was planning to do the flush then). In the meantime I can cut the nutes back to 50% of current with 50% runoff as you suggest.

I had a trip out of town last night, and they went about 26hrs since last feeding (I had been feeding 2x/day). Could that have contributed to this? I just notice the leaves today...

I do seem to be flushing about every 1-2 weeks!

If they are using a lot of water the PPMs of the nutrient concentration in the soil can rise but you would have to have had too much in there for that to be a major factor but yes.

Ok If you were getting the hang of this you would not need to flush so often. It is much better to under-feed than to over-feed but it takes practice and careful record keeping. You have learned a lot in just one grow. Keep at it and you will be a farmer in no time.

>>getting the hang of this
refered to my recognizing the likely need to flush again. For sure, AVOIDING the flush would be much more better!!!

thanks for the help!
