My First Grow!

Well I just realized that I have been only feeding my ladies 1/8 for the first week (48ppm) and 1/4 (70ppm) for the second week of suggested Coco Cal (Calcium & Magnesium) and I didn't realize I should have been feeding them normal dosing of UC Roots & Coco Cal, I was only supposed to be feeding an 1/8 & 1/4 of "VEG & BLOOM" nutrients, not secondary micronutrients, duhh SMH. Also my pH dropped to a 5.4 and because I had added to much pH Down on Monday, the Wednesday I realized I was depriving them of Cal-Mag which at a PPM500 scale was at 70ppm. I didn't want to waste the nutrients I had already used so... I added the other 30ml of Coco Cal and 45ml of UC Roots on Wednesday 29th to bring the PPM500 level up to 130ppm & brought the pH back up to 6.2 carefully and its been steady since, the damage has been done to the bottom leaves but it will grow better now with the correct Cal-Mag nutrients dosing. I can already tell today (Oct.1) they are looking much better 2 days after fixing Cal-Mag & pH. The Omega, Alpha, and Beta have started to grow again, the runt now has new leaves which it was not doing before so I know I have things going in the right direction now. Going by an Autoflower feed schedule with my Current Culture nutrients Week 2 of VEG is an 1/4 of the nutrient providers suggested recommendation for photo period dosing so... Updated my UC Roots & Coco Cal nutrients to the correct levels below for my 20 gallon system... UC Roots - Says 3ml/gal (20×3=60ml) so I put 60ml for the 20 gallon system Coco Cal - Says 2ml/gal (20×2=40ml) so I put 40ml for the 20 gallon system Veg A - Says .5ml/gal (20×.5=10ml) so I put 2.5ml for the 20 gallon system Veg B - Says .5ml/gal (20×.5=10ml) so I put 2.5ml for the 20 gallon system pH Down to 6.2 Starting week 3 of vegging 👍-10/04/2021
