hey the p4tm chef, pretty much standard magnesium deficiency , most likely due to the tough light schedule and the light being just a little too close, raise the light by like 2 or 3 cm and give them another hour of dark (you can give more but i'm guessing you want to keep the intensity up) OR you can put 1.5 ml / L cal mag in a spray and spray it on at light on and lights off ever 3 days for a week 10 days and the problem should stop spreading. hope this helps ! 🚀

White/Yellow snipes on leaves? (13th day of growth from seed)I noticed a huge change in my plant leaves in less than 24 hours. The leaves look like they are getting burned out. What is happening? I'm uploading pictures to see the problem and also the growth conditions. I'm watering once every 1 or 2 days (PH = 6.0). Not using nutrients yet

Veins turning light green on lower leaves One of my plants is getting light green veins on the lower leaves. Is this magnesium deficiency? I can't water currently without risking overwatering, can I just foliar spray BioBizz cal mag to temporarily help recovery? Or is this something else entirely?

Still to early to tell? Noticed yesterday and have slightly worsened today. Not sure the issue but potentially magnesium? Getting close to top dress also.Only on 1 of 3 plants so far. On older growth after getting dose of Recharge the other day. Maybe an N problem as I also use 484? Or mag? Using CalMag every other watering in RO at 150ppm as the soil has some cal and mag. Also getting close to top dress time maybe something else?

Yellow centre veins fan leaves Yellowing of the inner vein of fan leaves only. Also sporadic yellowing and blemishes of whole fan leaves but only some, others fine nice and green. All bud leaves and buds don't appear affected. Is it just that she's nearing the end of her life cycle? Or over water/over nute?
