I have some plants that are doing different but all bad things. 1st off they are all grown in coco gro and fabric pots. I was using 2 4ft 4 rod T5 set ups, but just put in a 400 watt MH and removed 1 T5 and left 1 T5. I also have a humidifier,and the average reading is 48-52% humidity at around 72F-80F . PH is around 5.0-6.2. I just now started monitoring the PPM,and it stays under 600. I read read read but tend to end up confused. -Please offer whatever knowledge you can. Thanks.
