Leaf deficiency. Need help to identify.

Well i was quoted, so excuse me for answering.

Fact is, depending on amendments and ingredients in the soil, CEC is going to vary.

There is such a thing as Anion Exchange Capacity as well.

Soil leaches, it absorbs, and it breaks down.

Tbf we can't accurately tell the CEC of a soil without a lab analysis. There's just too many variables.

Best of luck to you too.
I'm sure the info you provided will help the OP.

Cheers.

The fact that cec varies, is irrelevant to understanding the science of it. You seem to be all over the place with suggestions, but in the end, if it works for you, it's what counts! Your logic behind it however, is quite flawed! Take care as well!

Easy for you to criticize, yet you can't back it up with an explanation.

Not a problem, take it easy dude.

Yes I am going in soil.

I've been supplementing with Canna Terra - Flores. 1/2 recommend strength, Every other watering. From week 5 I added an additional PK13/14 at 1/2 strength on top of base nutrients. The issue arose shortly after, to which I then added more PK13/14 thinking it was a K deficiency the feeding after.

All 4 plants are showing the same issue, have also now been flushed with 3 times pot volume 2 days ago.

Thank you for the quick reply.

No idea about your nutes but don't assume that the magnesium in them is necessarily adequate: Also don't add one tablespoon/lime per gallon of soil right off the bat, it may be too much for the particular soil, add 1 tbsp per 3 gallons and then adjust as runoff dictates, easier to add lime in then to take it out

Just an update.

Growth returned to normal after couple of plain waterings. Resumed then with 1/2 feed once a week.

Chopped on day 69, nice amber trichromes observed with my scope.

Yielded 6.1oz from 60cm x 60cm space with a 250w dual spectrum HPS. Pretty happy with that.

Smell is piney and chemical/diesel.

Strong smoke. Makes me a bit of a retard though, going into rooms and forgetting completely what I was meant to be doing.

Upload a picture from just before harvest.

Thanks for all the comments.

Peace and happy toking.
