some help please- would be much appreciated.

hey first time grower here im growing dutch passion orange bud feminized under a 600w Hps in coco, only problem is my plants seem to be growin kinda slow?... is it normal for this kind of bulb to turn my leaves light green or even yellow? any help or advice would be appreciated.. i dont think im over fertilizing- how far should the light be above the plants? how much floragro, micro,bloom should i add to each litre water? the plants are on 6th set of leaves growing away on top but suffering lower down the plant please help

something is wrong..

leaves should be green and growth should be VIGOROUS... especially under a 600watt hps...

Stop feeding.. and make sure your water is PH'ed properly.. 6.5 +-

Sounds like you left some details out. You want help come clean.

coco stays very wet and most of the time the lack of oxygen causes the ph to drop and the leaves to yellow.
