If you are growing all autos your plants should do better under a 18/6 or 20/4 light cycle. I do have some autos under 12/12 at the moment but that’s only because I’m also growing photos. Before adding photos to the mix I ran my autos under a 20/4 light cycle from seed to harvest. They loved it! Also, regarding nutrients... Autos are a bit sensitive to nutrients. My autos ran into some nutrient burn issues when feeding nutrients at full strength, they seem to like 1/2 strengh much more. But overall i think your girls look well loved, keep it up!

Hey Happy New year! If you're doing autos are you testing how they'll respond to the 12/12? If so that's cool, otherwise you might want to bump up to 18 at least that would probably help with some of the stretching. Also the crispy tips are sometimes deficiency and sometimes toxicity...i think most people associate with toxicity though. Your fox farm grow nutrient should soon be removed if they're in flowering and keep just your bloom and micro nutrients in. Kelp(or seaweed) extract can be good for giving plants a little help also. Test out some things and find what works for you, at the least you may be able to stop the stretching and anymore leaves going bad. Happy growing, welcome to the community :v:

Hello and welcome to your very first grow. well i see Droopy Leaves , and Defoilation=? not sure of this. OK lets start.For having good results our plant need min. 18 hours of light. watch your watering its maybe to much. a plant in that size would need around 100-200 ml . For you future grow i would use a blooming fertiliser that is much poorer( 2-4-4) and using the actual one for the lsat feding before flushing. For more information feel free to

Changing the light to 12/12 will not make the plants stretch less, it will just make the flowering take more time. The stretch is mainly genetic, although it can be influenced by training the canopy, light intensity, distance between canopy and light source. Anyway that Flower Fuel is 1-34-32, right? I would not use more than 1 gr per liter, it's no wonder that you have nutrient burn symptoms, stop using it until the stretch ends, then you can resume it but only 1 gr / liter. I strongly advice you to get a pH meter and EC/PPM meter to avoid this kind of problems, good luck
