Discolored leaves, rust spots, and burnt tips
SilverSlapdickstarted grow question 3 years ago
Began with burnt tips, followed by rust spots on upper leaves. Then top leaves of new flowers came in yellow, followed by bottom leaves developing gross pale spots. Not sure why, please refer to my super soil recipe as well as the one feeding I did in week 5. Underfed, pests, ph?

i did look into your supersoil recipe and all i have to say is you are way over with nitrogen and with phosporus and not enough potassium at all.

Thanks @GanjaReaper. First grow in this soil, and my oscillating ac infinity is on 24/7 @ speed 6. Before planting I added a bunch of DTE crab meal, I’m guessing I should add more for cal and mag? Thanks again

Hi Jlimp,
Thoose brown spots can be eighter Calcium deficiency or a rust funges,
i think that in your case it is a Calcium deficiency.
I also spot some Magnesium shortage.
Make sure you add some and i think you will be fine. Just don't throw all kind of nutrients extra on it lol.
Is this the first or second grow on the same soil?
And how many hours a day is your fan running and how fast?
Good luck growing :)

The lower leaves look like what happens with PH being out of range. So I am guessing the upper is a deficiency from the plant not being able to uptake nutrients due to PH.

My autoflowers are getting bright spots on leaves. What could the reason be? (Week 3, no nutrients given yet because they are in all mix)What could the reason for those spots be? I suspect one of the following:
Nute Burn because my Autoflowers are in 75% Allmix.
Cal/Mag deficiency because my water is very soft and a bit high in natrium.
Light Burn because the DLI was ~25 when it should be 20

Is this considered as pale green due to insufficient nitrogen?This as a Cinderella Auto at day 34. I use mother earth's terracraft soil in a 2 gallon container. I feed her only Growth Technology Root Ultra from the beginning and add 0-5-4 tripart bloom for the last 2 feeding. Should I feed her nitrogen considering she is flowering?
