Sometimes PH fluctuations can cause this, or at least that's my last experience

leaf spots and curl
I have a few leaves with some spots and a few that have a side that curls. What do you guys think? Right now I'm just using Fox Farms Ocean Forest soil and water - I'm planning on adding nutrients this week. Will that solve these issues?

should I be worried about those little white spots, do they indicate on some kind of deficiency or they will go away eventually by themselves? I mean there aren't much but still, got me little worried.

Dark dots in leaves. Lamp burns?
I saw this dark dots in leaves but only she has it. She was exactly under spider-farmer sf1000 at 30 cm. Now I moved to other softer light at 40 cm. What do you think? Lamp burns? They're dry and curl up. Some images are edited for better appreciation but you have also originals.

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

Is that not enough calcium?
How can I recognise that it is only a calcium deficide? The plant is also the largest and the only one with such deficiencies. Could the plant also be lacking manganese or magnesium and what can I use to compensate for this? Are pests or diseases excluded?

Healthy?
Sie wachsen zur Zeit sehr schnell allerdings haben manche Blätter Flecken wie man sehen kann. Die ersten Wochen habe ich leider mit einem zu hohen Ph Wert gegossen (ca 8) dies habe ich jetzt aber angepasst und sie bekommen ihre 6,4.Vielleicht Nährstoffmangel? Bio Grow hinzufügen?

Ca,Mg,Fe,Cu,ect deficiency?
If anyone can see the third or fourth picture there is a decent shot of a deficiency. It's some immobile nutrient like Ca,Mg,Fe,Cu, ect. I just can't figure it out, been supplementing with CalMag fog almost 2 weeks? Any suggestions? Possibly Cu deficiency?

Any ideal what this is I've noticed it a few times before. It's like something has sucked the chlorophyll out and it leaves a see thru place that browns and rusts up. Mites, deficiency, excess?????

Hi growdiaries, Got a couple of issues on my plants here. The last 4 pictures show the problems, firstly there are holes appearing in the leaves and it looks like something is eating them. Haven't seen anything alive. Also a few spots appearing. Mould? Had bad air for a bit.

Is this nitrogen deficiency? Should I change the soil?
Is this nitrogen deficiency? I've been feeding them and using pH Down but nothing changes (pH 7.2). Should I replace the soil? They're in CannaTerra mixed with Promix. I've got some FoxFarm Ocean I could move them to.

Browning, curling of Green Crack leaves
Is this discoloration worrisome? Ph 6.1, adding 1tsp calmag to each gal, EC at 1.5. What's causing this browning? Seeing only on the Green Crack, mostly higher leaves, but some lower too. Does it need more or less of something? Leaves look "dirty".

The yellow spots that were seen last week have multiplied and started to appear on newer leaves. I should mention my tap water E.C is 0.8 so quite high. I still however added calmag this at it seems to look like a calcium deficiency. Are they to young for one though? Thank you
