Leaf issue - Orange specs and Yellow leaves

Lilmink · Jan 15, 2020

Ffof soil
I use compost teas twice monthly
Kelp/neem teas once a week
3 gallon fabric pot
Plant is an autoflower not sure the strain
Once the orange and yellows started i ceased the teas let it dry completely and flushed with 1 gallon of dechlorinated water two days in a row and there was no change. Just this morning i watered with a little EWC Tea and there was no change.

Damaged leaves wont recover even if the problem is fixed.

Let me know what you figure out. Both of my autos in soil started this way and got progressively worse. Make sure your ph is in a good range.

@Lilmink Do a slurry test of your soil to make sure in pot PH is in range first, also how are you giving ca & mg as dont see anything mentioned in your feeds?

I was under the impression weekly kelp/neem teas would provide enough Ca and Mg. I will test ph in a bit. Thanks

What do you think of excess manganese ? Could it be this?

To me it looks like you got a few things going on, the orange spots look like calcium deficiency, the yellowing is usually a sign of a lack of nitrogen, however other leaves are nice and green and you also have tip burn which is a sign of overfeeding.

That's why with these various issues lead me to believe you could have a PH issue causing lockout of some elements, also I have heard FF soil batches sometimes have low ph to start with like 5.5 - very acidic.

See ive heard that with the crushed oysters that is in the FF soil i shouldn't have to worry about PH, only my second grow on my way to get a tester now. Thanks!

I was also under the impression the compost teas and kelp/neem teas should provide the necessary nutes.

Learn to read the plant unless you’ve run it multiple times. It’s asking for calcium and magnesium. This point in flower especially she is asking for.

So flushing just water through is not what u wanna do.

If I were you I’d feed with a 50:50 veg/bloom feed with added cal/mag.
