Calcium or Phosphorus Deficiency?
One of my 3 Cream & Cheese has upper leaves on 3 stems/colas per the pic. The lower leaves are OK, the other 2 plants are fine. Thought calcium at first as phosphorus is more lower leaves? Maybe just add CalMag? Thank you so much!!

Copper colour, brittle dry patches, any idea what this is caused by?
Does anyone know what this is caused by? I've had it on several plants in the past, as well. I've looked it up, but nothing seems to fit. I'd appreciate your opinion. It's on a few leaves, which is why I'd like to know. Thanks, I appreciate your help!! 💚

Leaf problem, insects ?
Plant is approx 60 days old. I have found and washed off what look like insect eggs under some of the leaves but have not seen any webs or moving creatures. Is it insect damage or could it be fungus. I have 2nd plant that seems unaffected. Mainly lower older leaves affected.

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?

Calcium Deficiency? pH problem?
Brown spots on some newer growth now on both plants. Canna Terra Flores brings the pH of water down too much even at a half dose. I didn’t think I’d need to adjust pH much in soil. Any suggestions at this point? Thinking to just feed plain water to bring the pH up at the roots

Calmag or Potassium deficiency
Starting to show hard yellowing on plant #2 looks like it can be calmag Deficiency or Potassium Deficiency. I gave them a bit extra calmag a few days ago and it seams like things are not improving too much.

The young seedling leaves seem to have some sort of bruising. The young fan leaves are fine though, is this something to be concerned about or is it quite normal?

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?
