What is the problem? Please HelpHello everyone!
My plant is in 75 day. It’s Super Silver Haze and Photoperiod.
I use airpot and Coco soil.
So i can’t understand what the plants problem is. Maybe she has Mag deficiency but why leave tips are curly? (ridge)

RDWC issues-help please!The Lemon Auto seemed like it was on its way to recovery but it has developed a deficiency(s) - is this a Mg def? It has dark green veins and the leaves are a kind of dull faded lighter green to yellow. I just doubt it is because I’ve been foliage feeding Mg twice a week.Leaves. Veins - yellow between

Light cloudy green areas between veinsHi,
Two of my plants (3rd week of veg) have these symptoms on the middle level fan leaves (the biggest ones). Young growth looks ok. Doesn't look like anything in symptoms photos, closest thing is magnesium deficiency. What do You think it could be?Week 2

I’ve got a problem but not sure what it is. It appears to be yellowing in the leaves, maybe a magnesium lockout despite me adding magnesium and calcium. I had the same problem with my last grow but it’s much worse with this one. I’ve checked and calibrated my ph pen. Im blaming the soil which is Biobiz light mix. Please see photos for week 4 and tell me what you think. Thanks.Week 4

Yellow streaks between leaf veinsAll three of my plants have light green/yellow streaks in between the veins on the leaves that have been present since about week one (week 3 currently). Could this be a magnesium nutrient deficiency, PH issue, or perhaps just overwatering?Week 3
