Yellow spots on leaves
Am I correct in assuming that the spots on leaves were probably caused by ph fluctuation? If so, is there anything I can do besides flushing with proper ph water?

The worst thing I’ve ever seen
Today my friend send me some pictures and we don’t know what’s wrong, he bought some cuttings few days ago and now they are looking worse! Maybe you know what’s wrong?

Deficienty
Hi. What is it missing? Is it a lack of potassium and phosphorus? or rather due to weather or old age. This is an older leaf from the middle part of the plant

Leaf Issues
Hey all, my almost 5 week old Moby dick auto flower is starting to show some issues in the first week of flower. She got a dose of Veggie nutes 5 days ago, and a little bit of Bloom yesterday trying to fix it. Temps have been high and humidity low, would that cause this?

Sligthtly Yellow Leaves
I'm growing 2 Mephisto Canna Cheese seeds. Canna #1 is looking very healthy and green. Canna #2 is healthy (ish) but its branches are more spread out and the leaves are a bit yellow green. I'm trying to figure out if I have a problem with Canna #2 before it gets worse.

Bottom leaf turned yellow with brown on edge
Hello this is my first grow and had noticed a leaf turned yellow with brown spot on the edge. This is a northern light auto just kicking off with her flowering. I use advanced nutrients 3 in 1 micro grow and bloom and that's all I've ever used. I suspect a nitrogen deficiency...?

Yellow leaves
The lower leaves turn yellow Is it due to a lack of nitrogen, or is it self-defoliation of the plant? (photos at week 5) I look forward to your advice) Should other leaves be defoliated or left as they are?

To solve the problem of leaves, we did not notice any difference with an ec of 0.8 and 1.4. (group separated 2 weeks ago) :/ Any propositions? In hydroponics is it common for you to use power roots, green sensation, cannazym or the hydro A&B product really enough? Thank's

Lockout or deficiency?
I have an issue with a girl. Newbie alert. I feel it’s either calcium def or nut lockout. I fed with 1/2 rec BAC grow feed and it didn’t get better, so 2 days after I gave a flush of fresh water. Now it’s really trying to grow, it’s kicking out new leaves but it’s stunted
