Yellow leaves black tips

started grow question 6y ago
What’s happening with this plant? After watering all my plants 2 days ago, one of them has been quite droopy and developed these yellow areas with dark tips. Is it a watering issue / heat / deficiency? Thank you

Nutrient & critter problems need 1-2weeks from harvest need advice
The plant is a couple weeks of harvest but has some issues. (Some kind of nutrient lockout or deficiency can't tell what tho, pH is fine at about 5.8) And I got these annoying critters that seem to live on the soil (but aren't touching the plant) Any ideas on what to do ? :/

Calcium Deficiency ?
Got a little deficiency, can't find what it exactly is. Maybe a cause of this problem is that they got 3 days of nonstop light because I fucked up with the timer just before leaving house for 3 days

Can anyone tell what is causing these yellow tips on new growth on this plant?
I noticed my DLI was around 42 at the top of this plant so the light may have been too strong, or it could be a nutrient issue? Using CoM Stonington soil, plant is 26 days old. Haven't added any nutrients to the soil yet.

Please help. Last plant died exactly like this. Yellowing drying leaves from the bottom on all fan leaves while shoots get stunted / eventually affected.
Transp recently from 1g > 5g. Seemed ok at first day after (no wat) then leaves started rapidly yellowing / drooping. Tent is fairly small 40x40x120. Could it be the heat ? Also took out humidifier but still in same room tent vents. Is Canna Pro Plus watered between 5.8-6.2 ph ?

Week 8 (4 weeks into flowering) - Possible Nitrogen / Cal-Mag issue?
Plants show signs of what i assume to be a deficiency. Stopped feeding nitrogen Week 7 according to schedule. Symptoms are not on every leaf but some the upper foliage. Yellowing, burnt tips and rusty spots. My guess is lack of Cal-Mag & Nitrogen. Is my guess correct?

Yellow tips
New grow, new leaf colours! I think it could be over feeding, but would like to see peeps opinions if possible. Have stuck to the feeding schedule, but the fabric pots might be making things more complicated somehow?

Nutrient Lockout or Nitrogen deficiency (i.e need more nutes) or Fungus (see stems)
My leaves are yellow but some are turning green. Do they need more nutrients or lockout? I have not gone above 1EC but have seen both strains handling 1.5EC+ in other diaries. All three plants are drinking the water in trays. Res/Tray@ 6.0PH/653PPM. Coco slurry @6PH/500PPM
