Hi guys,
So yesterday I switched up my 250MH bulb to my HLG 550 Rsepc running at 200watt at a distance of 30inches and over night I have started to get white spots on the leafs of 2 of my plants.
I have raised the lights up to over 40 inches thinking it could be bleaching the leafs, and will monitor over the next 24 hours. If anyone can advise me on whats the issue it will be gratefully appreciated.
Strain: Autoflower
Pot size: 15ltr pots
Medium: plant magic supreme plus
Light cycle: 24-0
Light : HLG 550 Rspec
Nutrients: Nothing
Water: PPM 195 - feeding 2 ltrs wet and dry cycle
RH: 56%
I do have a diary up if that helps.
Cheers
