Leaves dying
I removed these dying leaves, they were burned, with signs of necrosis and curling down. Now the plant siting next to the "sick" one started to show some early signs, similar to what her sister showed weeks ago 😪 Does anybody know what is going on?

Spotted crisp leaves
What's up with these leaves? They've all been spotting up, crisp edges and tips curl. I keep flushing them and it helps. I feed them 1 tsp calmag to each gallon and often the mixture gets diluted as much as half. PH water was 6.2 but soil 4.5. 15" from 70% light.

There is a little bit of minor yellowing/browning in spots, on a few fan and sugar leafs. The plants otherwise seem healthy. Is this a normal part of this stage of flowering, or should I be concerned about nutrient issues? Thanks!

What could this be? Deficiency, or pests?
White Crack in coco, currently late veg / pre-flower stage. Canna nutes being fed at EC 1.7 / pH 6.0 with runoff EC 1.3 / pH at 6.2. Noticed this on a single leaf this morning. Only change in last few days is that I am now filtering my water before mixing in nutes. Any thoughts?

So this girl had a hard time when we moved her from a solo cup she flipped and we are worried maybe it’s from that but also wondering if it’s genetics...

What issue is this?
I have some dark spots on a few leaves, some looks like a cal or mag def but some are a little hard to identify. What do you think these are? These haven't had nutes, about 25 days old or so, Nectar of the gods #8 fed PH 6.3.-6.5.

Burned or finishing early?
So I'm very torn about what's going on with my Jack 47 Auto. There's part of me that feels I may have burned her, and another part that thinks she's just finishing early. I have details in the diary. Any insight about what I did "wrong" would be great!
