My leaves on middle of the plant have started getting lighter in the leaf margins its noticeable by the naked eye but i duno if it will show on on camera also there are tiny little yellow spots as if it been sprayed with yellow paint but they are so small looking on the web it looks like cal mag issues its alot worse on one plant and seems.to be spreading just wondering if anyone else has a suggestion of what it icould be if pics are needed ile try my best after work

That chart is not the best.......Some say it should be banned as it is misleading in ways......I don't like it much either.

There is better info available......look to that first....quite right Husse.

The fact th leaves are curling up on the edges like that tells me it must be some heat stress I know it can also cause yellowing not sure about the yellow margins tho, someone else may like to chime in but my bet is heat stress

Generally yes but it depends on what your circulation is like too, could also be completely wrong but if you do a bit of research on heat stress and look at some pictures you may see some similaritys

yeah i seen the the leaf rolling due to heat stress but i also seen that the tips can curl due to mag def so im still abit confused i will see how it goes if it gets any worse after i get the new ruck up and running ile know its not the heat thanks mate
