Burning from over feeding. Nothing to do with calcium. 18/6 is best for cannabis, they NEED sleep.

Why are my leaves yellowing. 6.5 ph maintained. Feeding fox farms tiger bloom and big bloom. Thinking it may have been from a late watering combined with the humidifier running out? Any help is appreciated

Calcium deficiency?
Saw this little brown/yellow parts today. She is in BioBizz LightMix Soil and gets 0.3ml/L BioBizz CalMag 3x per week. pH is above 6.5 . Today I gave her 1ml/L CalMag. Was this the right choice? Is this a calcium deficiency?

Dark purple areas on leaves — genes or environment/feeding problem?
What the heck is this? Is it just purple genes or a stress/deficiency or a combination of multiple factors? I have checked three visual cannabis plant health guides, and did not find a single issue which looks like this. Maybe a combination of 2 factors, but I'm not convinced 😐

When to start nutes
Anyone have any tips on when to start nutes on this girl? Her bottom single leaf is yellowing a bit and one or two other lower leaves have a yellow mottled coloring. Not sure if that’s from touching the soil due to LST or because she’s hungry. This is supposedly a low nute strain

Week 2, leaves yellow-ish mottling, pH too high?
That's my guess for now. I was going to use Blumat Tropf hooked up to tap but house water seems too basic. Only way I can think of remedying is to hook Blumat Tropf up to reservoir and make sure the water in it is the appropriate pH. Will that be stable?

Browning leaves sections of leaf surface discoloured
Day 18 leaf worries, browning areas, slightly metallic shine. I think from reading it might possibly be a phosphorus deficiency but I’m not certain so though I’d ask for advice. Thank you for your time and all answers are appreciated. Have a great day!

Should i worry?
Should i worry? Other growers said this is most likely a potassium shortage yesterday so I started feeding her a little more but if I compare todays pics to the pics of a few days ago I'm kinda shocked. You'll see which are the pics of today
