I've had this before, mine was due to calcium/magnesium deficiency, are you using calmag as part of your feed?

V-Shaped 1st pair of leafes /White Widow Auto
Hi i'm currently in my second 'experiment' to grow some auto's. The white widow shows 5 days after germination a v-shaped form of their first pair of leafes. The 2 Royal Jack's are slightly at the same path so i moved my GoLeaf X1 LED (150W) at 60cm distance.

Calcium deficiency?
Hello everyone, I need your help once again. I have just spotted some brown/yellow dots on 2 leaves of my plant. Did some research and looks like Calcium deficiency, but still wanted to ask you. If that's a Ca deficiency, should I add CalMag next time I feed her? Thank you ✊

Yellow edges
I had just dealt with a calmag deficiency but adding biobizz calmag, but now the leaves are starting to yellow on the edges. Is it still a calcium or magnesium problem, or is it something else?

Slow Growth and Leaf Issues
Transplanted outdoors over a week ago and have noticed slow growth and new leaves have little holes and yellow spots on them. I've checked for bugs but can't see anything. Could this be nutrient-related? Or shock? Ph levels? Too rich soil? Any help is appreciated. Cheers.

discovered some brown dots on the lower fan leaves. Should I worry? Not enough nuts? I'm giving my ppp auto BioBizz grow& bloom 0.75 ml/L and I'm feeding 2 L about twice a week. What ur opinion. ? The rest of the plant looks healthy.

Few splotches, anything to be concerned about?
Thinking this is because of the too humid couple of nights i subjected the girls to, by mistake. One morning the leaves were dripping wet, and in the propagator the humidity was insane like 98%. Have since taken out of propagator and starting nutes on Saturday.

Spider Mites Infestation
As the title says - my plant affected by what I think is an infestation of spider mites. I will treat the leaves with Cannacure as soon as I receive it in 2 days and I started with some home made solution of kitchen soap and vinegar. Safe to use other chemicals? Any experience?
