Pheno hunting

Hi growmies 👏🏻 so this week I’ve been again just battle-fielding this grow, all due to the Biobizz allmix deficiency trying light mix next so I have control over when and exactly when to start introduce bottles nutrients.. so I’ve worked out where I’m getting this yellowing and few rust spots on leafs. Some are just super hungry at 450ppm others at 350ppm so my next feed on the other girls will be a calmag/1ml bio grow/1ml heaven/1ml acti Vera Should help bump up the nitrogen levels & bit of P to sort out they red stems💪🏻 I’d say they still have another few days left of nutrients left in the soil as I ppm run off (some say in organic soil it doesn’t matter about ph & ppm and I can tell you first hand always check!) so al start a light feed next watering.. Also never noticed that my tap ppms were at 54ppm, so ive got to add Biobizz calmag like 10/15ml to 5litres just to even get an average base of 150ppm that’s even before nutrients are added.. anyone else experienced this? Or I’m I just adding to much? We’ll just need to see if any calmag deficiency’s show up but all looking ok so far. Hopefully get these other browns repotted up with in the week or so get them all on there 11litre pots and split them up and turn the other light on 💪🏻
