Veg plants roughly 4 weeks in are heavily stunted. At this stage they should be roughly twice the size they currently are. But for some mysterious reason they are very unhappy veg plants. Im running 18/6 light schedule in coco coir generally aim for 10-15% run off. Have recently discovered there are spider mites too but almost certain they aren't the culprit.
Running 3 different strains - Colour of Space, Lavender and blueberry.


light stress?? i'm running 200w LED in a 2.6ft x 2.6ft tent (80cmx80cm). The lights are roughly 30inches away. Plenty of space between lights and plants - i would be surprised if it was that

Environmental?? Temp is a steady 25 degrees Celsius/77 F with humidity around the 60%

Equipment?? Bluelab PH pen and EC reader are both brand new so I don't believe im getting faulty readings

Lock out?? EC levels are 1.6 ~800 PPM (hannah) with PH around 5.8. Run off levels are reading as you would expect



Could someone smarter than myself please help me out lol am running out of ideas as to what the issue could be. Im wondering if it may be a definciency perhaps, but not really sure.

Any help/suggestions would be greatly appreciated

I'd say there are nutrient problems, both excess and deficiency. I haven't grown in coco coir, though.

Looks like heat stress, try increasing airflow or moving the plants to a cooler location.
