Autopot Coco and Canna

Good luck with your grow mate!💪💪

If you won't reduce nitrogen, next your question will be about yellowing leaves and rusty spots. Nice setup !

good grow buddy

Good Luck! Wish you the best! 💪🙏💚

It's rust fungus. I had the exact same problem. It took me 2 years and 6 wasted grows that cost me thousands of dollars to find the answer. Solution is commercial fungicid like Myclobutanil, Trifloxystrobin or Difenoconazole. My plants looked exactly like yours.

with your skill , great autoflowers genetics and autopot you can have great results! . the shape and dimension of your plant is awesome, you did great in my small opinion; but I can't see trichomes production..and so smell and aroma and taste looks poor to me .....just my little advice...throw in the bin all synt nutrients, (I spent a lot of money on them with mediocre results), stop getting mad about ppm EC ph and go with organic dry amendments and only water in the tank. tank management will become a breeze.. just add some epsom salt for magnesium if going coco and LED. I never had a smoother grow with autopot and only water strategy. no mixing no time spent on measuring or getting mad for right ppm. just a great mix at the beginning and then only water. Trichomes production will increase significantly..you see your leaves have so few trichomes.. we grow our loved plant for those trichomes... have fun and off course no bending no scrog no defoliation ..nothing apart from natural expression of plant phenotype.

my 2 cents.. take off airdome and pot socks.. add a timer that opens its valve and let water passively come in they trays.. aquavalve is still needed for preventing overflow. set it for 5-10 min every 24 - 12 - 8 - 6 hour depending on plant stage and needs. you will have much more real dry periods for the roots..that will grow amazingly healthy..you can start to turn on the system early with no risk off root rot or overwatering. ph and temperature of water in the tray will be much more close to the water in the tank and roots will not seat in water even during dark period (assuming autoflower 20/4) also humidity will be much easier to manage.

Nice girls 👌💪🌱

Looking great good Luck for the futur 👌💪

All the best 💪 Happy growing mate 🙏 💪 😇
