Problem during flower...

My last two harvests about 5 weeks in my plant leaves starting "drying" out. Mostly towards the top of the plant, the fan leaves coming out of the bud for the most part. They get crispy, shrink, turn brown/yellow and then just die. By the end of the harvest (10 weeks) the upper half of the plant is pretty much dead looking. The bud is not tight, it does have alot of crystal still, smoke well but little weight and easily turns to shake.

I am running 8 600's in flower, 3 gallon pots in fox farm dirt, running Botanicare nutes, pro bloom, hydroplex, sweet, liquid karma during flower, pro grow and cal mag during veg. Room is 77-81 degrees, 38-50 percent humidity. 5 week veg time under 2 600's. ideas what might be going on?

thanks!

Maybe the lights are too close?

what strain?

8 600's? holy cow!

You need a silica like pro-silica by grotek or dutch masters gold silica. any brand silica will work. It helps the plant retain moisture and makes the plant handle higher room temps.

also pics would help. You might be over nuting the plants, but can't tell until I see some pics.

photos, the ones that look good just were put into flower a week ago, the one photo that looks bad has been in for 6 weeks.

Looks like maybe some nute burn.

just as I figured nute burn plus your ph is off. flush with plain water ph at 5.8-6.2 for a week then go half strength on the nutes
