hi folks,new to the forum and my first grow and have a major prob i'm hoping you could help me with!
these were grown from seed and put into veg 5 days ago(18/6) since repotting they have started to yellow.they were healthy before veg and still have new growth.
they are under 2 600w mh bulbs in cool tubes.
they were potted in a general potting compost from garden centre and have had no nutes.
temps vary from 20(lights off) to 28(lights on)
humidity is in between 35 and 50.
they have plenty of extraction and air movement.
they have been watered til compost was damp once since repotting.(water is 7 ph)
one plant (pictured)is the worst but all seem to be showing signs of the same yellowing...
help!
