Mephisto Pro Mix Advanced Nutes

Week 3 - Feb 15 - 21 I have been trying to keep to a ppm schedule: Seedlings: 100-250 (nutrients aren't needed here, hence there's not a lot of particles needed) First Half of Vegging Cycle: 300-400 (this is usually after you transplant, which still doesn't require many nutrients) Second Half of Vegging: 450-700 (you'll start giving your plants more nutrients at this stage) First Half of Flowering: 750-950 (your plants will be eating more as they grow, so they'll be taking in more nutrients) Second Half of Flowering: 1000-1600 (this is when your plant's eating the most, especially if you give it additives) End of Flower, Entering Harvest: As close to 0 as possible (this is when you'll be flushing your plants, so you don't want there to be a lot of particles leftover) My tap water was about 400 ppm so I purchased 5 gallons of RO water. I had to put 5 ml of ph down to bring it to 5.9. That with the 0.25 ml/l of nutes brought it a bit high to 446 ppm. The ph as 5.9. The watering on Feb. 11 was with tap water, much ph down, 0.1625 ml/l of the 3 nutes as well as a tbsp of Epson salts and 0.75 of AN Sensi-Cal-Mag which resulted in a high 870 ppm. I actually had to water the solution down to these amounts as the ppm was way to high. The ph was 6.1 Feb 18 - The large DG has burnt curled up edges and the 24 seedlings were getting light burn on the little leaves. I dimmed my light to 50%, which I believe would be about 232 Photosynthetic Photon Flux Density (PPFD) at the centre and about 115 at the 3 foot mark where I now have the seedlings. I watered Feb 19 with a slightly stronger nute mix but after bubbling the solution overnight the ppm dropped 442 to 409 so some of the nutes must have evaporated off. I positioned the light so it is not directly over the seedlings. After one day they looked less droopy and healthier. The large DG got some bad burns on the leaf tips but the newest growth does not show signs of burn - I will keep the light dimmed until the seedlings take off. They have developed a new set of leaves Feb 19 - watered with a liter each. the DG are 3.5 and 2.75 and the CD is 2.5 inches tall at watering. They seem to be developing. Feb 20 - The smaller 24 seedling doesn't seem to be developing and the burnt DG's newest growth is not burnt at the tips. I raised the light to 30" and will see what that does tomorrow. ght to 30" and will see what that does tomorrow.🙏
