Just going by that leaf it looks like a minor Ca defiency. For a reliable diagnosis you should always provide all the possible data about the conditions and pics of the whole plant under natural light.

These look totally fine and nice healthy plants to me. Good job! Don't sweat it, I would add some light CalMag (max 0.3EC raise) to the feed as at this stage it might be in demand.

I dnt have an ec meter I dnt even ph water straight from the tap with no problems we do have very gd water here and with that soil its self buffering so no need so say I got Epson salts how much off this would u think I would use a pinch in a gallon off water or would that b 2 much? thanks

I would personally refrain from using Epsom salts since I do not have experience in using it. Rather use some proper CalMag product that has Ca, Mg and iron properly balanced or if you cannot get some, perhaps better not to do anything extra at all. If it ain't broken you shouldn't attempt to fix it. Looks just good to me really!

Just pick up something simple and cheap. I use General Organics Cal/Mag 0-0-0 NPK. I get it for $13 a liter.

A liter of Calmag will last about a doz grows ... or a tsp per gal of Epsom Salts but I agree w/ Med growers analysis ... plants look to be starting the last phase of their lives where the fans begin to dry off ...

:smoking: I'm with Med', that's Ca defc., a minor case fortunately! Don't bother with epsoms, they have no Ca in them, only MgSO4,... Ca is needed in pretty high amount for canna', and a dedicated Ca-Mg supplement is the right way to go for treatment and prevention with regular use,...
