Hi. I'm having some issues with my plant. It started showing these spots a week and half ago. It started on the lower leaves and every 4 days or so it moves up to the next node. Last 2 feedings I gave her micro grow and bloom from advanced nutrients (ph perfect line) at a ph of 6.8. Last 2 feedings I gave it 2ml/L of each bottle. With my most recent feed I also added 0.8ml/L of calmag as I read that it might be a calmag def. So far it stopped but want to double check this with some of you. I added a photo if the potting mix i use. Those spots start kind of a silvery color. It looks almost like some sort of liquid hit the leaves but I didn't hit the leaves when watering/feeding. I added some photos when they first started showing up She is an autoflower currently flowering. It has a few pistils on the top half of the plant and its outdoors. I also added some photos of the full plant. If you need anymore information please let me know. Thanks

Hiya bl2001.
Welcome to 420.
Can I ask a few more questions?
What size pot is the plant in?
How often do you water the plant?
it could be just root bound.
The 'soil' That you're using is a concoction of different soiless medium and has some food already...there's a possibility the food hasn't run out before you used the bottle nutrient.
I've never used ph perfect..it seems to work for some growers and not so good with others.
I'm used to applying my nutrient at ph 6.3

Hi. Thanks for replying. pot size is 2.9litres. Recently, I been watering the plant every 2-3 days. depending on the weather. if temperature is very high usually 2 days. I checked it this morning to see if its rootbound but it doesn't look like it. I've seen plants that are root bound completely covered in roots and its full if roots. This doesn't look like some rootbound pictures I saw. I checked my runoff EC about a week and a half ago. Same time I started giving it bottled nutrients and runoff EC was measuring at 0.13. so there was very little left in the "soil"

Yeah that doesn't seem rootbound, but will most probably need a bit bigger pot to finish flowering.
I'm guessing the age as around 4 or 5 weeks...I'd expect to see a few more roots for that age. It's possible that you overwatered when young slightly.
But for your problem with the leaves...that could be a issue with the ph. I don't know enough about AN ph perfect nutrients to advise. Like I said it works great for some, and not so for others.
Let me call on @bluter . iirc he has some history with these nutrients.

She's actually in week 6. 37 days since germination. This is my first grow so i might have overwatered it because of the fear that she doesn't have enough water when she was younger. Now it looks like she's slightly drooping. Probably becuase i took it out of the pot for the photos. Hopefully she'll recover

She'll be alright.
It's common to ovetwater when a new grower. Everyone has that fear of not doing enough.
Your plant is actually looking really healthy. I'd expect it to finish well.
It may just need an up pot to a bigger container and good watering cycle .
They like a wet/dry cycle but new growers get nervous leaving it long enough for the dry part.
When the soil dries it draws oxygen dowm to the roots.
