Super Lemon Haze Auto - Possible issue

Sup Guys,

I have a greenhouse seeds super lemon haze auto, it is been in veg for about 2 weeks then in flower for roughly 2 weeks. I am experiencing some yellow leaves but there quite a few dotted around different levels of the plant. I'm hoping it is just a part of the process of an auto strain and the yellowing is its natural process.

I looked about the deficiency section but i didn't see anything auto specific so thats why i'm in here asking. I have a pic here if it helps. I am growing in magic soil , which is a really really light soil perfect for autos i am told. I am using BB nutes, grow, bloom, and topmax. Grow is on 1.5ml , Bloom is on 3ml and Topmax is on 3ml. All numbers are per litre of water. I don't plan on going any heavier on the nutes and keeping this mix right through now. The PH of my water from the tap is perfect also. I'll maybe have to test some run off water for PH but with my other photoperiod grows i have never had any issues.

Is this just natural do you guys think? My first auto so a bit on edge with everything and any changes!

Is your soil amended with, or do you feed calmag?

hey bro, i don't use CalMag. I have never needed to use it in the past but i was using biobizz all mix on my photoperiods. Is magnesium related to the type and ph of your tap water? I have a bag of epsom salts there that i picked up one day in a bargain store just incase something like this ever happened. Do you reckon this type of soil being extremely light has lead me to a Mg deficiency?

It's possible. Calmag is really the only thing i did not read you state as using in your grow. Check your runoff PH and that will tell you a lot of whats going on. Im no expert, thats just my two cents.

Ok thanks for your help i will check tonight lights aint on for another hour and its due a watering so will post any findings back here. I'm hoping its just the yellowing of leaves that may be different from photoperiods which i am more used to. If not maybe i'm needing to add maybe a .5 ml extra of grow per litre to up the nitrogen. It will be good experience to test all avenues and see the results.
