Super lemon haze auto Led Coco

Hello @Blinkin ! I have worked with AN at the past but no matter the company its the same principle. Its all about VPD. Let me explain. The higher the VPD is the higher the transpiration of the plant is and that means higher rates of water loss. When the plant loses water it drinks more and with that water it is also taking nutrients that are diluted in the water. At your case the VPD is at around 1.29 kPa while you should be ( ideally ) at 1-1.1 at this stage of growth. That is a difference of 17.273 % upwards, lets say 17%. Having that in mind you should reduce the EC of the fertilizers that you should normally use at this stage of growth by 17%. At this stage you should normally be at around 1.2 ms/cm and that value reduced by 17% is 0.996 ms/cm lets say 1 ms/cm. So at 1.1 ms/cm you are close to perfect. Any way a 17% difference is not big deal. The problems are starting at 25% _ 30% difference and as the difference raises they become more severe. You also need to give them more water. You are using coco with perlite, don't be afraid. Happy growing ! 👊
