Mangnanese or calmag deficiency

[chronogimp]

Scratching my head on this one. I have a pretty simple setup. Foxfarm ocean forest with growdots nutrients. I have about 30grams worth of food mixed in to 3 gallons of soil. Food instruction state about 10 grams per gallon. Was originally feeding at in between 6.5 and 7.0 but once into flowering started seeing what's in the picture. I can't tell if it's possibly manganese or cal mag. It looks more like manganese to me. I ended up flush with 6.0ph water and adding about 10mg of manganese sulfate into the water during flush. Also used the same solution to foliar feed. Just doesn't seem to be getting better. Any ideas?

Whatever you nute issue, do not fret. You are in late-stage flowering. That means your super fantastic buds are sucking up the remaining nutrients from the leaves. Completely natural. You can let them fall off on their own or give them a yank down at the stem and get rid of them.
If you planned of flushing, consider doing it. Maybe another dose of flowering nutes.

What makes you think that this is "late stage" flowering?
chronogimp - when did they go into flower and are checking the pH of the run-off water?

[Gingerbeard]

The flowers.

They are looking frosty on the buds 👍

I have been checking the runoff periodically. It normally checks out just fine at around 6.3ish. So you think i should just let them go and suck all the rest of the nutrients up? This is the first time i've used growdots so i was not totally sure. They do smell nice and the frostyness does look healthy.

I'd leave it alone. If your pH is in check and it's only effecting a few fans, you'll be fine. If you absolutely must try something, maybe add some Epsom salt in ur next watering and wait. So, how many weeks into flower are you?

[Gingerbeard]

No. I am not going to suggest stopping or starting anything. I am going to suggest considering things. While what I said is true, others will suggest to try adding stuff to keep that from happening.

6.3 is a tad low in flower, old the PH at 6.5-6.8.
