I have these little urkle plants , and since the early stages of life , some of the leafs seem to have what appears to be a deficiency of some sort , rust looking , nutrient burn , cal mag deficiency ? Does anyone know what this might be ? Or how to take care of it ? Everything else in my tent is nice and healthy .. but these few plants seem to have this issue .and have since the beginning stages of veg .. I’m gonna flush them again with straight 6.1 ph water . Using bio bizz , power si . And cal mag occasionally. Anybody might know ?

I don’t believe it’s the food , My whole room is extremely healthy , same feedings on all the plants . I plan on giving just these 2 plants that seem to be throwing off this deficiency , 2 solid waterings of pure ph water . Just in case it is a mag deficiency or some lockout … these seeds were made about 6 years ago from csi . I was curious if someone knows what this deficiency might be . Here’s a pic of the health of a different cultivar in the same room . I don’t believe it’s the feeding .

So they look like they are hungry and you plan to starve them?

Edit: different pheno's need different feed schedules
No two girls are identical

Lol it’s a picture of some old fan leaf veg growth , but I’m starving my plants lol . Im
Curious of how you can determine that off a old fan leaf ? I don’t believe I am tho.. because it’s a lighter green .. I have a few plants that are almost black from genetics . My whole room is extremely healthy . I believe it’s a deficiency of some sort . thank you tho , I’ll up nitrogen etc on these 2 phenos next feeding .

I'm running 8 plants all the same strain, all the same soil, nutes and everything.. But they all have individual needs..
What works for one plant doesn't always work for another.. I had one plant that looks similar to yours, I did a cal/mag
foliar feed.. The spots didn't go away but it stopped spreading.. Another needs more N than others and they all use different amounts of water.. Same environment!

Are all your plants from the same clone?

If not you could have different phenotype variations from within the same strain (assuming they are the same strain)

To me it looks like this plant has been under feeding slightly so this could account for the spots.

It looks similar to a Ca deficiency but not exactly like a Ca deficiency.

I would UP your feeding ppm on this one and see how it recovers.

if leaves begin to darken and the spots cease to spread then you’ve found your answer.

if leaves begin to darken but spots continue to spread then increase your Ca intake for the plant or alter your pH of intake solution to accommodate more uptake of Ca in that range.

If you look at the first and last images you can see the plant it's attached to is a consistent light green. Since N is a mobile nutrient that is what I expect to see when my plants are hungry.

As was previously said each strain and sometimes phenotype within a strain can have different nutrient needs.

I would listen to @Herb & Suds @jondamon @lusidghost @HydoDan @myke and possibly me :blsmoke:

PS looks like a Ca def.

awesome man , that’s what I’m gonna do , is a light cal mag foliar spray .. and I agree with it being a lighter green , and probably lacking some nitrogen .. and all genetics have different needs . Need to quit being lazy . Lol . I’ve had successful runs using same ratios also , but I need to focus on

awesome man , thank you … I totally agree with it being a lighter green , and most likely under fed a little . and every plant having its own needs . . Multiple genetics , all require specific ratios and I know that .. just lazy with it I guess .. need to focus on that .. don’t believe that I’m starving it tho . I will definetely up the ppm on these specifics phenos … it’s all a learning curve . Thank you again man , for the knowledge .

All from seed . No clones .

There is a sentence that I always say to people when it comes to feeding.

It’s easier to correct an underfed plant than it is to correct an overfed plant.
