Any ideas on this?

started grow question 7y ago
I'm guessing this is some sort of deficiency. Some of the spots are rust like and occur and young and old leaves. Any opinions? Advanced Nutrients 3 part. No supplements.

Looks like Calcium deficiency to me mate I'd foliar feed the leaves with some calmag and some chelated iron couldnt hurt either

I agree calcium deficiency is most likely the problem. Calmag will solve the problem.

Droopy leaves, curling at tips, and now brown/yellow splotches on leaves in DWC. Not sure what the issue is
Unfortunately, I can only write so much here, but I have a lot more details in my grow diary. The droopiness started about 3-4 days ago, but now has started showing deficiencies in the leaves, and plants seem stunted on height. Day 19 since sprout.

Plant #3 (pic above) started as a sprout with discoloration. Now on its 4th node, the plant is still affected. Some other plants seem to have it to a lesser degree. I learned it may be TMV, but they are healthy and growing well other than this slight discoloration. Any thoughts?

Rusty leaves in flush HELP
As a result of being stuffed in a cupboard for nearly 3 days without proper ventilation some of the leaves on nearly all of the plants have developed rusty looking leaves. I am only a week away from crop is this something to worry about should I just ride it out or take action?

Cause for mottling leaves?
I think this mottled leaf coloration may be due to slightly high pH or just stress from the repotting over the last couple of weeks.. Most leaves are fine but a few look like this. Any thoughts?

Novato con manchas en hojas DWC
In the fourth week of flowering, spots started appearing on the plants. It's a DWC grow, and I'm not sure if it's a deficiency or excess of Calmag or something else. I'm a bit of a newbie. Can someone help me identify the problem? pH is about 6, using GHE tripart nutrients. Thank you very much!

Brown spots on Day 5
I have noticed some little brown spots on the leaves of my PPV. Can anyone help me out with what they might be. I am day 5. I probably saw them slightly on day 3. PPV is pretty hardy so should I just chill and wait and see?

I have some yellow spots as can be seen in Week 3 Day 20 pic. I am not really sure what it is or how to get rid of it. It appears to be on lower few nodes but not upper one so far. It is not affecting other plants in tent at this time.

Is this septoria or alternaria? The plant is doing well, buds are not affected (at least not now) so I hope it’s septoria. Few weeks till flowering complete, do you think I can carry on with it? Please tell me it’s septoria and not alternaria. Thanks to anyone that will respond

Please look at the leaves shown, orange and dried parts. I asked a similar question earlier but these look more damaged and I'm wondering if it's worsened due to my setup. Wind damage from fans? Water damage from humidifier? Light or heat damage? Managing VPD is tough. Thanks!

The leaves on my plants seem to have some markings appearing, I havent yet given any calmag. The plants are in their 4th week from planting seed. Also seem to have some nute burn going on. I do have some biobizz calmag, should I use this and if so at one strength?

Started LST but now plants look a bit sick?
I attempted to do LST but I think I've maybe started too early as some of the leafs started to wilt kinda bad afterwards. Was careful not to break anything. Edges are curling and have discolored. I have a feeling they're a bit short too? Photo from 5 days ago and today.
