These are Bourdeline extreme 2nd reveg. I have one platinum LED and one mars grow led lights. When it first happened I raised the lights all the way up in fear of bleach effect. I check back 48 hours and it's back. How do I fix this? Growing in 5 gallon smart pots soil is fox farm & fox farm nutrition. pH water has been 6.5 I'm just starting out and this is the 2nd grow. Any advise would be great.
