Is this nute burn, or something else?

Everything was going well, then i added Sensizym to my mix, (Connoisseur a+b bloom, and Big Bud full strength) while it hardly upped my feed ppm, my runoff spiked hard. That being said, it was a while since i did a flush, so i am not sure if the Sensizym caused it to spike, or if it was just a salt buildup.

Sensizym breaks down organic material correct? If so that would cause ppm spike would it not? Either way i flushed with twice the amount of water i would normally would have. Then because i run a hempy bucket that has a passive rez i cant drain, (next run that will be fixed, major oversight on many peoples part) i fed full strength after, so it was diluted back to the ppm i was running before all the problems started. 1540 With the Sensizym the feed ppm only went up a little bit, but the runoff jacked up to 1840.

My next feed will not include a flush, so i will back the PPM down to around 1300, then only put in half dose of Sensizym.

Also when this all started, i also was not able to get to them in time for feeding, it was delayed for 2 days, so that is why i am wondering if its nute burn or a deficiency because they were deprived for a few days.

But other then this recent development things are going good considering how it was all started, couple prevegged plants that were never trained to be in a scrog, and had major deficiencies when i got them.

Nice job turning them around!

That looks more like K def to me... For full disclosure, I don't use Canna nutes, I don't measure ppm. All I'm saying is that looks like K def (which can look like nute burn in the beginning, i.e. burned leaf tip), especially since you have a bit of chlorosis going on.

They did go two days longer without water then they should have, they very well might have cannibalized a bit. They were doing fine before that, so i cant imagine i need to increase K, just make sure they dont run out of it again. Ill keep en eye on it, and see what others say about the Sensizym with spiking ppms.

Thank you!

Looks like calcium def.

Whatever it is, i think it was caused by not watering soon enough the last time, i will just have to stay on top of it better. Also working up a simple auto watering system, just a gravity fed system that comes on for so many seconds, then shuts off for 12 hours or so, to extend my feed times. If i could extend it to watering every 5 days, instead of 3 that would be great.
