Manganese or magnesium

[Chefbjy]

Hey all lightly amended roots organics water only. No ph monitoring no bottled nutes. Molasses, langbeinite tea, kelp tea and water with top dressing of fish bone meal and langbeinite. 2 week harvest window left and now seems there's an issue.

I'm thinking the lime ran out and I may have overwatered the last time I watered with molasses. Only had run off a 3-4 times prior to issue. Ph was good when last checked. Using well water with nuetral ph from an artisean well (aquifer). With trace minerals .2ec and less then 100ppm.

My concern is that it's not on older or lower leaves as symptom checker suggests one of these deficiencies do. The top growth is effected and some sugar leaves look a little yellow with same spots.

I'm considering a chop if the issue continues to compromise my sugar leaves. I'm planning on reusing the soil so I don't want to add bottled mag. Do you think lime would help my situation being so close to harvest? I can also try some epson salt. Or should I use both?

I'm looking at this on a small screen-
I wouldn't add lime here and it may be a good time to check pH.

add some P&K as that is what I'm seeing- mostly lack of Phosphorous or locked out.

if if you still feel it is magnesium -use 1 teaspoonful of epsom salts- to at least 1 liter of water.

I'm listening for future reference. 👍

I've given her lots of k so far and think my ph may be on the low side will have to check next watering. But never thought about the p so it's possible it's locked out. I'll look into some different k options but the only thing I have on hand is dry fish bone meal. 3-16-0. I'll probably have to go to the grow shop and get me some liquid...don't think side dressing will help at this point.

I should have top dressed again after 30 days but I forgot. Thank you Weed Pharma.

FYI- I use Growbuddy web&app to keep track of nutrients,etc

Just checked ph with a good amount of run off 6.5 so I'm going to add some liquid fish bone meal 0-10-0 by Down to Earth. I don't think it's locked out but I did forget to add more p...organic beginners mistake 😆.
