Okay so we are approx 21 days since seed Light cycle is 18/6 under 2x 135w led Medium is about 60/40 premium potting mix and vermiculite. Water is approx 6.8ph Plants are watered to run off as required (when I can stick my fingers ask the way into the soil and it is dry) Nutes are seasol for flushing one a week and dead powerfeed the day after the seasol. Both mixed at 2ml:1l Recently lots of yellow leaf tips and is getting worse. Thanks in advance.
the vermiculite is holding excess water hence nutes,...time to potup to a round black plastic pot of about 3-5 usgallon, no vermiculite this time but perlite is a better choice, avoid nuting for 2 weeks on until you see a positive response, even then avoid nuting so much
