i have a green crack in hydro showing the deficiencies you can see in the picture. Not sure what it is. 1st time growing this strain, my others don’t really have issues. I adjust ph daily to 5.7-5.8, so usual ph range is 5.7-6.2 plant is growing very well and drinking roughly 1-1.25 gallons of water per day. Thanks

It does look like calcium to me as well.

Here is a little read on the matter. pH is a common cause of calcium lockout.

Using Flora nova nutes. Been giving 5ml gallon cal-mag, maybe I’ll bump it to 6. Maybe this strain just demands more. I took 2 more pics of leaves that are way worse. Thanks for the input.

Still looks like calcium, but those leaves are awful dark. How is the rest of the plant? Wondering if you're adding too much of something and locking it out?

Consider what you need (Ca) and what you don't (perhaps Mg)...the point being if you can impart what you need without adding more of the other, you'll be better off. As mentioned above, it's possible you're locking out Ca via a pH issue or too much of another element/s.

putting in more cal-mag will not help they have plenty of food.... keep that ph 5.8 to 5.9 my green crack and ak 47 dont like anything below 5.8 while pineapple express is not bothered by a little lower ph

what is your hydro set up
