Phosorus deficiency

Hi guys just wondering if anyone could help, I have a few rust patches on a couple of leaves is this a phosorus deficiency cheers

Looks more like a calcium and magnesium deficiency too me. What nutrients are you using?

Haven't used any yet just re potted the other day and soil has nutes in to last a few more weeks.

agreed. Use a CalMag nute mix. Also you have slight yellowing starting. Also ad a bit of nitrogen.

I've got these two autos that looked lyk they have a nitrogen def the bloom I'm using has a npk 5-4-9 will this fix the problem cheers

Heres the pics

The 5-4-9 should take care of the N deficiency. Check the label to make sure it contains Ca and Mg. If not you will need to supplement those.
