Spots and yellow leaves

[nothernbud]

Hey everyone I’m in week 4ish of flower and I have little spots on some fan leaves and lower ones turning yellow. I’m using Remo nutes and I haven’t checked ph during this entire grow till I started noticing these issues.

Air pot and fabric pot
Crop king autoflower northern lights
315cmh lighbt
Promix soil
Tap water
Remo nutes
Not using a tent
20 degrees Celsius
40% humidity

This is only my second grow which has been a huge improvement over the first

It looks like a potassium deficiency, perhaps more. I'd give her a good feeding, and increase the bloom by 50% for it. If that stops the progress of the symptoms, drop back to 125% of your current bloom level.

Note that this could have been a nitrogen deficiency if it showed up earlier. As you were well into flower when more potassium is needed before it showed up, I went with that.

I found this a while ago I use to check things sometimes, its been handy and also this diagram for helping solve any problems

Those are two of my standard references. They are both excellent places to start.

Ok thank. I struggle with the diagrams due to being colour blind, I’ve been folllowing the feed chart exactly as shown. I’m currently feeding 8ml per 1 gallon. It says for larger more aggressive feeding you could go 10ml. Like I’ve said I haven’t had one spot of trouble till now we’ll into bloom using all of the remo products

Here is a couple new updated pictures of what’s going on.i should be thinking of flushing for the finals but I guess not ?

From the pistils, you've got a week to a month to go yet. The are still mainly white.

I no but I’m around week 8 already and with all the yellowing and dying leaves I’m thinking I need to flush it good and start with the nutes. My other plant is going a little slow but it hasn’t had any issues so far

Give them both a flush with 3X the pot volume with water. The bath tub is handy for this.
