So I’m using clones I filled my fabric pots with coco+lite 70/30 the company told me I shouldn’t have problem with cal-mag but just in case to flush them with 0.5ml/L before planting I still used 1ml/L cal-mag and flushed them and planted my clones on the next day I have them under 250w hps lights 55cm above the plants . Temp at day its around 28 and night 22 They are 18/6 cycle and yes I’m providing CO2 and small humidifier humidity it’s around 50/60% yes I’m using ventilation silenced revolution fans . I’m using sensi coco advanced nutrients ---

Pic number 2 i def see mag deficiency in the top n bottom big fans. Are those the same clones? N is it worsening daily? Id bet that 6.7 runoff is an issue. Try going in at 5.5 see if it gets u closer. Is ur ph pen calibrated? ---

Sure looks like a pH problem. Maybe lock out, can’t get food through her roots she will eat whatever is in her leaves. Looks like you might have to start flushing with some very low pH water to get it corrected. Good thing is correction should happen faster than if you were growing in soil. Good luck hope you can correct everything and save your plants which you should be able to do with these people on this forum helping you. Fill out that trouble ticket you will get a lot of help. Stay calm don’t stress. [Next page](https://ilgmforum.com/t/cal-mag-problem/35518.md?page=2)
