    Default Answered: Light green leaves with rust help!

    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.

    The white spots id say are pests ie spring tails or thrips, could even be spidermites, take a look under the leafs with a loupe for any suspects.
    Maybe a idea to give them a flush and start again, i'd be feeding every day too tbh if in a coco mix."

    What Clunge said above. Looks like a PH is out of range a bit..get him to take some runoff readings EC and PH.
