Brown spots

[LewisR19]

Evening chaps, I need a little help identifying what’s wrong with my girl please. It’s not on many leaves at the moment. Tonight I gave her a feed of 4ml per ltr Bloom and 0.25ml per ltr pk, and she took 4ltrs

White Widow Photoperiod
4 weeks in to flower
Was a 6 week veg, so on its 10th week
15ltr pot using B&Q verve
Plant magic organic grow/bloom/pk

This has literally come in a day-day and half

Epsom salt only has magnesium I use epsom salts and cal mag in a foliar, I may be wrong so let's hang on for another opinion

Cheers mate, yeah I’ve never fed cal mag directly in to the soil. Hopefully the cavalry arrive soon

If your in soil and Just to stick a pin in it you can give it a small dose of Epsom salt, a level tea spoon diluted into 3 litres of your next feed then give it a week you should get a spurt of nice green looking new growth from the hit of magnesium but if them new leaves develop the same brown spots you'll have to dive a bit deeper, either way a small feed of salts in soil even organic won't harm

I disagree mate it dont look like magnesium deficency so I wouldn't be putting salts through the soil cant see how it would help, try get down to your local canna shop and get a bottle of calmag

Looks like classic calcium deficiency to me. Is it just the leaves nearest the light? If so it is even more likely to be calcium deficiency.
