Reserva Privada The OG #18

Listen ! Your soil is pre-fertilized , that means you don’t need to add any extra nutrients for about 4 weeks after each transplanting ! You will realize that you will almost never use your Veg nootz in a crop when you grow in soil , maybe just once or twice maximum if you transplant only once in middle of Veg this is where you will be using your Veg nootz for the first 3 weeks after the switch to 12/12 to support the stretch ! You must understand that nutrients company won’t be making any profits if they were selling soil only , you see what I mean ? This is why they pull out insane feeding schedules based on utopian scales ! Plants are Autotrophic ! As they can’t move to get there food they must create their own based on symbiosis with bacteria’s in the soil ! Nutrients are just used to enhance a good grow ! It’s easy food ready to serve ! As they don’t need to process it to be available for the roots ! Those spots are Phosphorus excess ! At this stage seedlings seek for Phosphorus, as the N is stocked in the cotyledons and K is only used in the flowering stage ! So ! Don’t freak out bro 😊 You just need to transplant them in a bigger pot , around 1.5l pot to start the Veg and you will be transplanting again later in their final pots after 4 weeks in the 1.5l pot. Your mix is good enough to use only plain pH’ed water , which is really cool as you have no mixing nootz to do . You will be using only your Bloom nootz mostly and saving a lot on your Veg nootz . RO water is like rain water , it shall be around 20ppm max between 7.0 to 7.2 pH . But as you’re growing in soil , and will be transplanting twice in your crop , you might probably need some Mag/Sulfur by the end of flowering but you will realize there’s everything in your bottle of Bloom nootz 😉

Hi @MansionMarijuana! Well I think you overwatered your cups, and as a result, roots are suffocating, they're not able to handle nutrient intakes anymore (nor to breath oxygen). Plus, RO water has nothing to offer to the roots, if you don't add nutrients and have a light medium/soil, they will encounter deficiencies. What medium are you using (brand/name)? My advice would be to transplant them into bigger containers, let the medium dry a bit, then give a good meal (mostly Nitrogen) and see how it goes. If this is not getting better after a few days, come back here to find help, we will refine the diagnosis based on your latest pictures and informations. Hope this will help, keep us up-to-date and happy growing 👊

Good luck with the grow ;)
