What is your growing medium? If you’re growing in soil I highly doubt it’s a cal/mag issue as there is plenty of cal/mag for a grow in most quality soils, more likely you’re Experiencing pH fluctuations in your medium.

Vague, though I would probably use calmag...but then, I'd probably also add a bit of sulphur and phosphorus if I have some.

1.0 ml of calmag per 1lt will do it wonders for next week or 2. Then start lowering it 👍🏻🌱❤️🍁

intervenal discoloration, organic grow
Gave her enzimes last week, maybe they were too much or some nutrient lock out due to a somewhat excessive fertilization (too much vermicompost) Think I will go on with plain water to the end I think maybe the problem will sort out itself or wont degenerate too much. Any advice?

Deficiency?
Hey everybody, I’ve never really dealt with deficiencies in autos as most of my experience is with growing photos outdoors. Does this look like a magnesium deficiency? These just appeared over night on just two of my larger growing white widow autos. Please let me know, thanks!

Whats going on?
So.. 6th week into it. My leaves have various brown spots and yellowing spots in no particular spot. There is some browning on leaf edges. Also tips are up. I am thinking cal mag and to much heat. But not sure. I lifted light up and so far nothing. Also started adding cal mag .

From day 50 some leaves of the plant started to turn yellow. I had stopped nutrients due to an overfert problem. So, on day 50 I started with the nutrients again, but in lower doses. 2 week left to harvest. What should I do with this nitrogen deficiency? Should I worry?

More rusty spots
See this now on more and more leaves. Only upper fan leaves that get good light exposure seem to be affected from this and also the clawing. Have backed off the nutes completely for now and will add ground egg shells to the water in the hope its a Ca deficiency.

Could anybody help point me in the right direction please? Are these plants showing any deficiency? If yes, what is it? Noticed that some leaf blade edges look lighter and the older leaves are showing some yellowing between the leaf veins. Thanks in advance!
