Hi @IGAutoGrower! Your environment conditions and your feedings seem fine. My guess is that your HID light is out of order. Over the time, usually 6-12 months, HID bulb's efficiency decrease, because of the huge voltage pulse it gets each time the lamp turns on. The age of your ballast can also explain why the light's PAR efficiency has dropped. Finally, the temperature in your grow room has a role to play, indeed, HID bulbs are built to work in a defined temperature range, basically they need heat to reach their optimal spectrum and brightness, and a cold air coming onto the bulb can cause a noticeable reduction in it's efficiency. How old is your HID bulb, how many hours have you been playing with? Same question for your ballast? Do you have a fresh air intake coming onto the light? Hope this will help, keep us up-to-date and happy growing 👊

To me your plants seem ok based on what I see in you're diary you might be feeding them to much . I can see some yellowing on the lower leaves leading me to believe your are feeding to much and getting locks outs because of it . This might also lead to stunts in growth because the plant is stressing out to much . Nothing really to be concerned about tho , I would just reduce the amount of times you feed with nutrients and feed PH corrected water in between feedings . I'm not sure how strong your light is because its not written in the stats but what I do see is that your light is really really close to your plants . The 2 plants might not be getting enough light as a result they are growing more dangly the your other one . I might suggest getting a stronger light in the right spectrum and having it dialled in at 20 inches away from your ladies this should help promote the growth of a kick ass canopy loaded in tops , I also see that you have topped them although topping is common practice with auto flowering strains can stunt growth big time as its hard to judge when the plant is actually going to start pre-flower . I'm not saying it can't be done I'm simply saying done at the wrong time can cause HUGE stresses that your plant does not want . Over all you just got a few things to think about and dial in and you will be rocking and rolling cause based off of what I see you're already in good shape and well on your way . I hope this information helps you ! -Happy Growing!

Height doesnt mean much, what matters is the number of nodes and tops. If all the plants are affected it's possible that it is an environment issue, like low temperature. Over watering can seriously affect growth too. Check your light distance too, there are some really stretched plants in the pictures
