First autogrow

Growing at 24/0 is not ideal for plants, despite what the autoflower crowd advocate. Cannabis plants NEED a rest period every day for a correctly functioning metabolism There are certain metabolic processes that only occur during the dark period. Without a dark period, these processes can not occur, leading to plants with messed up metabolisms. A plant with a messed up metabolism will never be as healthy as it can be. 18/6 is the healthiest choice. I am sure there are many who will say "but I have grown for ages at 24/0 and my plants are killer"........ but could their plants be even better with a correctly functioning metabolism?

Overwatering is kind of a boogeyman... it's hard to do unless engating in poor watering habits. 1) fully saturate (if soiless, also get 10% runoff. 2) wait for appropriate dryback and repeat. That second part is what people most often fuck up. But people are also irrationally afraid to fully saturate a pot, which is the proper way to water. Make sure it drinks down enough water between irrigations. Deoth of dryness and weight loss relative to a saturated pot are the 2 best ways to determine the need to water. some media hold less water per volume than others. So a 'heavy' soil you may want to wait for 1" deep to dry but in something like coco that holds a lot less water, you trigger an irrigation sooner relative to depth of dryness. Usually when the surface begins to change color it's safely ready. So, there's a bit of range of dryness that will not lead to problems. Those curling leaves are a bit worrisom... as with any chlorosis on new growth... if it corrects itself quickly, it's less of a concern. pH swings can contort new growth, so can some trace element issues, which would be rare, but could be locked out by pH. not enough info to diagnose with confidence - you can reference any leaf chart to see the same. Check pH and adjust watering habits if they deviate from the above. Ensure climate is kosher (high vpd?).

Looking good keep doing what your doing
