Blinkin started grow question 3 years ago
Hello there,
is there someone who have already used the Advanced nutrients in order to give me some advice about the daily dosage, particularly upon autoflowering sativa strain?
Moreover, with high room temperature (about 30° C) how often is it recommended to water daily? Thanks

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 ! :facepunch:

Autoflowering strains are - most of the time - very sensitive to nutrients intakes, so there's a global advice about manufacturer's feeding schedule: don't strictly follow them, since they're made for photosynthesis strains. Usually it's a good idea to start with 1/4 to 1/3 of the brand's feeding schedule, then slowly increase to 1/2 if the plant is healthy and reacting well after a few weeks. In high-temperature environments, you need to water more often but with less nutrients. I think you will need to water almost everyday, but don't forget about the wet/dry cycle (each phase about 24~36h), it's crucial for the roots and the plant's health. Hope this will help, keep us up-to-date and happy growing :facepunch:

Ive been watering my small seedlings daily too , i took a shot glass whith 2 cl, for not to overwater them. For every other question ( feeding sehdule of coco ) i would recommend you to read a helping site, took to long to write it down.... https://www.growweedeasy.com/coco-coir

when you water you should try to be very precise and not over do it, like even divide the water up into smaller containers. Since you're in soil you want to make sure you follows the soils's wet dry cycle so wait a bit until it gets dry before watering again. Basically the seedling is in a container that's too big for it right now, so you want to water a bit further away from the seedling so it stretches its roots out to get the water. That's why at this stage you dont want to over use nutrients , maybe start directly with bloom nutes around week three. keep the cal mag though, for sure. Water every two to three days - even down the line. Good luck ! :rocket:

I have not used Advanced Nutrients specifically. But I feed my plants once per week (on the weekends), the rest of the week they get PH'ed water only as needed. Hope that helps. Good luck!:+1:
