Trainwreck - Need help diagnosing

[insane420]

This trainwreck mother is in day 29 of blooming under a 600watt light. I have her in a 5 gallon bucket with FFOF soil with 25% perlite. I have been feeding her per the FF website schedule on an every other day feeding. I noticed the problem about 6 days ago and I have backed off the feeding to 1 time a week. I always adjust the mixture up to 7.5 - 8.0 so the runoff measures around 6.1. I have also been supplementing with Cal/Mag at 5ml per gallon at every feeding. The big fan leaves are mostly impacted and the new growth seems to be fine at the moment. Here is a picture.

First Grow - Trainwreck

Im not an expert but id say...It sounds like your PH is too high...I dont like to have mine higher then 6.5, i always shoot for 6.2-6.3...You may have a nutrient lockout problem...

And maybe a Picture not under the HPS... do you have a Tungsten mode on that Camera.. so we can see it a little better...

Best of Luck

What are ur PPMs like? In my last grow I had 3 plants in 1 pot that all did that with the fan leaves after I uped the PPMs. Could be the source, I'm unsure. Now's the time to listen to ur plants. Forget the FF instructions. Ur plants leaves are telling u other wise. If ur 29 day in bloom I'd flush for preventative measures.
