Hope I'm using this site correctly I'm as new to this as growing . I have a few questions . I have 5 autos 2 to 4 weeks old growing in fox farm OF and have so far fed no nutes , last time I watered (3 days ago) I tested run off ppm and got a high reading of 1800 .plants seem happy and are growing like crazy . I have the fox farm trio on hand and my question is should I start nutes on any of them or wait until the ppm comes down first ? I know fox farm OF runs hot. Please take a look at photo and any critique or suggestions would be appreciated.
