Any ideas on this?

started grow question 6y 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.

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

Slight discoloration in the leaves
The leaves are starting to get slightly discolored on the edges, what could be causing this? Could it be the white flies? Or could it be too many nutrients? I am giving the plant a bit of Canna A and B, although it's meant for hydroponic, it's all I have at the moment.

Curled leaves occurred in both veg and flowering tents only to my purple trainwreck plants. Checked leaves with a loupe and couldn’t see signs of any pests at all. Only occurring on my PT plants in all tents. Other strains seem 100%. Only on large fan leaves, any ideas or help?

Yellow leaf tips and edges
Hi I've got a problem that I've seen from the start of my grow and it's getting worse on older leaves now - zoom in edges and tips are turning yellow. I thought it was magnesium so I've dosed with Calmag but it's not improved - I'm Ph6.5 - any ideas?

Can anyone help me identify the cause of the rust-colored spots on a couple of these lower leaves? I am guessing some kind of nutrient burn.

Hi 8th week of flower. Bottom leaves have turned yellow and died and yellowing is rapidly moving upwards. I think it's nitrogen deficiency so I've added more Biobizz Grow. Would be good to get an expert opinion! Thanks

What's wrong?!?
Help! I thought I had this. Is this calcium deficiency? I've been using treated water (1tsp CalMag+ 1tsp Grow Big per gallon). It's just getting worse. See photos and descr. from past few days.

I'd like to know what happened to my plant but I'm unsure how to properly describe it. The photos in my diary should be able to make it more clean (W18). Maybe it was botrytis but I caught it on time? Or maybe something else? The trichomes got dark orange where all this happened!

Possible rust on Auto orange sherbet?
First time with this strain, Auto orange sherbet from fastbuds... Soil pH is 6.5, soil test showed good amounts of NPK...we do have a natural magnesium surplus in our soil, but it never causes issue, sprayed with neem and Arber... Looks like rust?

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!

Hello. When I watered 3 days ago, I saw some brown spots on the lower leaves and thought I had got some nutrient solution on the leaves but now it's on the next set too. Any idea what is going on? All 3 plants are being treated the same. Thanks Chuck.

What's the issue with this leaf?
Can anyone help identify the issue on this leaf. Dreamcatcher is the strain and I can tell they were a reveg. It was root bound and I thought it was an issue with the roots. After transplant outside and sprayed with my IPM the plant has recovered but still has a few like this?
