Could be an iron deficiency. Doesn't look like calcium deficiency.

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.

Yellowing on lower, older leaves. Starts with crispy tip, curling downwards then slowly progress to the whole leaf. The leaves haven't started falling off yet but I feel if it doesn't get resolved soon then this will be the next step. Thanks for the help.

Leaves curling on sides
Okay so the leaves are acting weird and kinda curling in on the sides. Like it's heat issue. I think maybe to strong LEDs. Idk. It's only 79°f Light (ESv300) is on lowest setting @32in away. Fed GH flora trio. Only 237ppm. The leaves are also yellowing between veins.

Does that look like an early deficiency?
Hi everyone, what ya thinkin' What kind of deficiency could that be? My bet - potassium. last portion of water was ~6.2 pH I wasn't feeding her nutes for ten days by now. Because previous runoff was ~2000 ppm. I thought would be a good idea to do just water for a while.

Crispy Yellow Leaves
Inflow EC=1333 w/ PH=5.8 vs Runoff EC=658 w/ PH=6.0. Insufficient nutes due to light intensity? Perhaps my PH meter is inaccurate? Light is 42 inches from canopy or ~600 PPFD. RH 65%, Temp 80 F.

Is the plant just maturing or something else?
I don't think this auto CBD plant has long to go. It's at 59 days of a supposed 65. I just started to notice a some tips beginning to discolour and a couple of fan leaves have small yellow spots appearing. Is this just the plant ageing?

Leaf issue
What seems to be the issue with older and new leaf growth here? It looks like cal-mag or potassium deficiency in my opinion, but I’m not really sure.
