Yellow Leave - Deficiency or Ripening?

I want to believe its a deficiency of some sort but definetely not excess although it could have lockout due to the schedule, mix of fertilizers, the medium or a combination The photo above is at 8 weeks, in that time it would have only received a total of 10ml FFTB which is the only P i'm adding at all, and only got 5ml FFGB during vegetation. The feeding schedule every week is water(BC-CalMag), water(BC-Silica), feed(FF Trio) and here are the feeding ratios. Times mixture was fed x Amount in ML x PHd (5.75-6.5) water Used 6 x 2.5ml BC Silica to 1L Water 6 x 2.5ml BC CalMag to 1L Water 2 x 2.5ml FFGB to 1.5L Water 4 x 2.5ml FFTB to 1.5L Water 6 x 2.5ml FFBB to 1.5 Water(Was mixed with FFGB/FFTB depending on stage) What do you fellow growers think can be upped or lessened down on? At this rate i may never finish the FFGB as we have low limit on amount of plants that can be legally grown simultaneously but i'm just wary of nutrient burn with FF from the past. Thank you for all your input, this is very much a learning experience to me.😁

hey there Sashatt, sorry but i gotta disagree with my growmies on this one. the NPK ratios are off, but it's P excess, meaning lockout. there's just too much P in your food , meaning you NPK ratio is probably something like 1-6-2 but it should be something like 3-6-6 , so you have P lockout, so you're seeing signs of P deficiency which is the discoloration, yellowing, but you're adding plenty of P , so it's a lockout. this can be quite bad, so hopefully you figure out how to fix it. usually you want to fix your NPK ratio so it's something like 2-4-4 , flush once by watering until runoff then add 20% more water, then feed once after that correctly, hopefully the plant will recover in about a week's time. Hope this helps ! 🚀

She is just hungry for nitrogen. Or your light is too close. I would not provide much nitrogen. Nitrogen deficiency starts from bottom up. So yellowing at lower leaves first. If this is not the case your experiencing then it is your light is too close. Good luck and happy growing 🌱

I think you dropped your nitrogen level a week early so there isn't as much in as she needed. Nothing to worry about she will fade a little faster that's all.
