Mold/Fungi
Today I've found white spots on some of the leaves. What could it be? Mold/Fungi? I've been strugglin real hard to keep the humidity below 50%, but due to the constant rainstorms I only manage to get it to 54% at daylight and 58-60% at nightime :(

Are CBD-Strains less nutrient-hungry?
Hey Guys, i experienced that these strains like a lower EC/TDS. Every time i went over 1.2 EC (600ppm TDS) they showed signs of over-nutrition, like very dark green leaves and reddish brown leavetips. What are your thoughts on this? Are CBD-Strains less hungry on nutrients?

Leaf stems change color
Greetings, dear Growmies! Growing NL auto by Sensi On 2 of 3 plants the petiole (leaf stem) turned red on upper (facing the light) side. The bottom side is green. Is it a sign of any deficiency or disease? Couldn't find on the web.

I know it's probably nothing to worry about since this is my by far best growing plant right now, but it doesn't really look like a mutation, more like damage or something. This is the only leaf i encountered, just wanted to check if anybody knopws what it is, hopefully no pest.

2 of the very bottom leaves yellowed and fell, and 2 other started to show yellow parts, It seems to have stopped now. Wondering if it's due to the high heat and very dry air, or if it's nutrient related. Thanks!

Not sure what's causing these purple leaves and leaves drying out. Plant overall seems unhealthy near the end of flowering, any suggestions appreciate
This Dos si dos Auto has been struggling over the last couple weeks with upper leaves turning purple and drying out/breaking apart. The buds also look strange to me but that may just be from my inexperience. I'm growing in organic soil and have dry amended twice, 18 days apart.
