Dual strain pheno hunt. One strain is experiencing bronzed/rust spots. What could be the cause? No pests/eggs to see. Assuming deficiency
Soil: Gaia Green Living Soil amending with 3 TBSP/g 4-4-4, 25% worm castings and 4 TBSP/g wollastonite
Water: 80 mL daily

I would try adding some CAL/MAG as i have been down that road before! Also check your PH.

I am a first time grower myself and noticed this on a few of my plants. I discovered the cause was water droplets from feeding them. The nutrients I use are rather strong and leave a white residue on the leaves when dried, and this affects photosynthesis. That is my observation in my first grow anyway.

Brown Red Round Spots on 4-5 Fanleaves / fungus ?Hey folks, I have this issue with one of my ladies. There are small reddish-brown spots on 4-5 fan leaves, while the other plants don’t have anything. What could this be?
I think it’s a fungus, but I want to be sure and know exactly what it is before I start treating it.

Tache cuivrés sur feuille.Je me demande si les tâches cuivrées sur les feuilles de ma plante de cannabis et d'autres plantes sont dues à une carence en calcium ou en phosphore/potassium. Les feuilles affectées sont généralement les grandes feuilles, souvent nourricières. Voir agenda.
Je vous remercie 🙏🌱

Day 4, after emerging. Is this coloration on the cotyledons okay?Humidity is 55 - 70, temp is around 20-24c, 50w full spec led
It's my first time, and i think i have been watering it too much
I also fed it 2-0-0 npk water with 4ml per liter and I since learned it's not okay. Will it recover? Is this too little grow for day 4?

What is causing this Leaf discolouration overnight after a lot of tent work yesterdaySpent a lot of time in the tent yesterday. Everything was fine and this morning there’s bad discolouration on the leaves of some plants.
I did lower the plant (was way too high) so may beight burn - but it’s only on some plants
I did make two mixes of water/nutes

Possibly Potassium Deficient? Based on ALL the pics I could find, but not sure.I noticed these brown splotches and leaf edges on one area bud and pistils of my Orange Sherbet last night. Based on what I can find online, this might be potassium deficiency?
This is mostly on one spot near darkest edge when tent closed. Thanks!

Leaves are gray/brown and curl down. HELP!Im a first time grower and I cannot figure what’s wrong. I’ve been feeding it Calmag and Grow from Biobizz since last week. 1 ml/l grow, 0,8ml/l calmag. PH of water + nutes is 6.3.
The soil is coco and pearlite.
Did I give it too many nutrients? Did I overwatater?
