Hi guys
My friend has asked me to help him. His plants are growing fine but the leaves arnt as green as we would like. A couple of leaves had rust on them but this has now spread to all of his plants. There are also little white dots on most of the leaves.
He has 8 plants(5 weeks in veg) in 30L pots. 3x 600w hps lights. Ok air circulation an temps around 78-80 F. He gets his EC around 1.1, PH 5.9. Uses Dutch pro take root an multi total. An cannas mag cal. Hand feeds every other day.
Looks like rust fungi with maybe some kinder insects. Anyone got any ideas what the problem is and how to fix it?
Thanks in advance.
