Week 6, had some brown & yellow spots starting from the middle of fan leafs spreading out and curling up a little. so 2ml of calmag per 1l water ph at 6 stood for 24 hours and also a feed of 7ml sensi bloom part a per gal and 7ml sensi bloom part b per gal with 3.5ml per gal sensizym for root health.
Maybe overwatering allways use 1/4 of nutes for autoflowers pal or half dose if they are strong and healthy... feed light but let them dry up before you next feed 🌱💚
Also the ffs need 12/12 light cycle too flower and the autos wont like being lowered too that from what I've found... auto need 18/6 throughout 🌱 happy growing
