this a cal def?

Totally not familiar with that line. I would use something high in K only, perhaps a kelp extract.

I use algen extract which to my knowledge is a kelp extract.

Looks like nute burn to me, try flushing for a few days. A good flush never hurt nobody.

I believe you are correct.

That more often than not should look like a nitrogen deficiency as opposed to Ca.

 

[Georgekush22]

If those were the uppermost leaves I would say it's unequivocally a Ca-. But it's mid-plant, suggesting a K-.

Seamaiden, correct me if im wrong but doesn't a Ca deficiency usually start on the lower leaves as opposed to the top?

Nm just looked it up it usually shows up on new growth. :rolleyes:

If it's a cut, then whatever deficiencies the mom started with will be carried over to the cutting.

Damn learn something new everyday. Thanks for posting that.

No, it occurs pretty much exclusively on the top leaves, and this is because Ca is immobile. Therefore, it cannot be translocated to new/growing plant tissues from older plant tissues the way, say N can be translocated.

I would say adjust your ph to 6.5 and lower you ppm/ec way down. If you in early veg think 800 ppm, not sure what that is in ec, for regular waterings, right now I'd say go even lower a flush for at least a week. Keep us posted
