Droopy leaves and discoloring at the bottom leaves, what is her problem

[enoughskunk]

Problem: Droopy leaves and discoloring at the bottom leaves
-Medium/grow method: Plagron Light Mix - 3gal smart pot
-Feed and supplements used: AN Sensi Bloom 2ml/L TanG Auto Schedule
-Water source: Filtered tap water
-Strain and age : Auto Northern Lights day 35
-Climate: 30/16 celcius outdoors
- Light used: 8-9 hours direct sun
-Additional info: Also suspecting mites maybe?

Hey guys, these photos are from my youngest plant, Auto Northern Lights. She is at day 35, she has discoloring on the bottom leaves as you'll see, and the weird thing is her leaves are droopy under the full sun. Additionally, she has orange-ish spots and white-ish spots at some of the leaves. Can you take a look? Does she have a deficiency aswell? or is it watering problem? I give her around 2 liters every 2 days with 2ml/L AN Sensi Bloom when the pots feel light. I don't think I'm overwatering, maybe underwatering? Thanks for you help once again, I appreciate it.

@enoughskunk Welcome to AFN. There are several things working here. Droopy leaves can be from over-watering but many other reasons as well. I think your night-time temps are getting too low 20°C is as low as you want to go. The length of day is short so the plant will be smaller from this. Some plants just droop!

What is in your Tap Water? PPM, PH, Chloramines?

A couple of leaves looks like Phosphorus deficiency? but I would suspect a PH problem since AN is not going to be short on P. I know they advertise you do not need to check PH but this just is not what happens out in the field. You need a good PH soil probe to check the PH in the root zone. Get a Blue Lab leap soil probe and meter or an Accurate 8 soil probe or the clone of it. Don't buy cheap ones they just do not work.

One of the leaves looks like you may have some thrips:

You need strong magnification to see the little critters. Look under the leaves I recommend insecticidal soap or Spinosad products follow the label directions.
