pH is fine.

Tablespoon is 15 mls.

3.9 liters per gallon.

For measuring mls you can get a syringe from your local chemist/drug store/whatever you call it in England/UK nations. Or you can try ml measuring devices intended for uses in cooking/chemistry, etc.

Don't know about using pk a week before harvest. This doesn't sound right. I'm guessing it's only a phosphorus/potassium fert. I'm thinking that you use this for the entire flower/bloom cycle, but you might want to throw in some nitrogen fert, to keep the plants green during flowering. CANNA - THE SOLUTION FOR GROWTH AND BLOOM

Yellow dots - if there are no bugs in your grow space, then this could be magnesium deficiency, as this usually shows up like golden-yellow spotting on the upper side of the leaves. If Canna doesn't say anything about having mg (magnesium) in it, then you probably need to add some. A cal/mag product will do nicely.

Plants look pretty good, but will outgrow such a small space. Either move some or you'll have to trim them back quite a bit. People put alot of plants into a small area apparently forgetting that the plants will grow.
Your so right mate thanks , magnesium deficiency it defo is , Should i use that in the next feed with cal? , i will be using plagrom alga bloom at the same time will this be ok ,. But the next time they will be feed will be monday ! Do you think it will be ok to wait until then ?

And i have been using a ml syringe
