sorry, I'm not seeing 'light burn' there ... not good photos, but it looks like some magnesium deficiency goin' on there ... I know temps are ideal at 75, but my cabinet is in the 90's almost always (it's 105 outside, today), and never any visible heat damage ... ya might do a good pH check on your run-off (soak the hell out of it with 7.0 water, then measure the first bit of run-off) ... this is a good link for plant problems: International Cannagraphic Magazine Forums - The Complete guide to Sick Plants,pH, and Pest troubles!

the image reaper Reviewed by the image reaper on . Yellow stripes, crispy leave, discolouration. Hi all, we have 2 plants under a 400w HPS. They are being given Bio-Bloom nutes, in the correct doses. The water is at around PH 5.5-6.5, 2 liters every 3 days. It will be 30 days into flowering tomorrow, but over the last few days the leaves are beginning to get yellow 'burn' like stripes. This is only on one plant specifically. I hope the pictures attached will show what I am talking about, any information as to what can be done to prevent more of this and what the problem is would Rating: 5
