Ok. Anything else? I thought it looked like na deficiency too...

I can't see other deficiency from this pics. Maybe other peoples can but my experiance is to there. But you have ca def for sure maybe from lockout or enething else, or she is just hyngry. I have exactly same experience with ca- on my fastest growing strains start with yellow tips on new growth then progress to two rusty spot on both sides on blades on leves then necrosis. You can see a lot of pics on my gallery. I know a lot of people will tell you this is nute burn with this yellow tips but from my experience its not its allwais improve when I up ppm with cal mag

Here are some extra infos on the grow if that helps. I am growing a single plant in a 4x4 in a 8gallon airpot. I am following the canna feeding schedule at half strength and watering once ever 2-3 days. Soil is canna professional plus. PH is about 6.5 and temps/humidity are where they should be. The strain is mango haze. Someone told be a shouldn't be feeding her at all which I dissmissed since I am in a pretty light soil( how is she supposed to get her food)

Your pH is too low.

 

[grower7155]

What should it be? Do you think that's what's causing all the trouble?

 

[Chimera]

take pH 7 water and run it through your soil and catch the runoff. Check the pH of the runoff and then come back and tell us what it is.

 

[grower7155]

Runoff is at 6.5.

 

[grower7155]

My plan is to increase the veg nutes up to 2/3 strength and add a little cal/mag. Sound about right?

Once I had similar problem and my runoff was 6,6 ph so I was quite confused. I thought it is leaf mold or some other disease. Than I brought another ph tester from a friend and realised that mine was complete crap. Real runoff was 4,7ph but that time were most leaves already burned. Calibrating didnt helped, I was 15 minutes in ph7 calirating liquid, than i measured runoff again and PH shown was again 6,5 or so eve if it was nt true.
