Is this a nutrient deficiency or surplus or something else?

So I know this is probably the most commonly asked question of here but this is my first grow so I’m new to all this, gorilla glue auto, 9 weeks in, been flowering for about 4 weeks, 5 gal pots, 6.2 ph water , happy frog dirt, fox farms nutrients, was previously only giving small doses according to this chart l of the nutes but the last two feedings I gave it a full dose each time. I have attached my feeding/watering schedule below this. Does anyone know how much longer these might take until harvest? Waiting on tricome change. And how much dry yield can I expect?,

Good Evening @Payton
That looks like a tiny bit of nutrient burn.

@Flitme should reduce the amount of nutrients I am feeding them?

Bump your input ph to 6.5-6.8 range for this part of the grow. From the pics they look further along than 4 weeks of flower. Great looking plants!

@BobbyDigital how much longer do you estimate these plants to have left? I lent my microscope to someone and haven’t getting it back yet so I don’t know what the tricomes look like yet

Hard to say from those pics but they sure look further along than 4 weeks

@BobbyDigital so almost exactly 4 weeks ago it started growing the white pistols, that is when it starts “flowering” right?

Yeah that’s when I start counting. If they’re really only 4 weeks then you should have at least another 4 weeks to go.

@BobbyDigital how much more bud do you think they will grow in 4 more weeks, I have no clue what the dry weight will get from these plants? Any ideas from the pics?

No telling the weight from pics. Really need to be able to see, feel and squeeze. As for the buds, they should double in size. The last few weeks being the biggest swell.

I think you should stay the course whatever you are doing because the little,yellowing/ browning tips is a good sign that you are feeding the plant enough but not harming it …

I used that schedule but outdoors with the liquid and dry trios only and cal mag your plants look really healthy

I’m a noob and never grew inside …

Also I grew 2 photos topped them and they reached 4 feet in height
Total dry weight was 5&1/2 z each plant
One airy strain ,one dense that didn’t seem to matter

Look it may be little bit burnt from nutrients or it maybe early potassium or phosphorus deficiency as flowering plants need more potassium and phosphorus
