SLH and gorilla glue browning question

[Jsimp342]

Hello everyone I have 2 SLH and two GG plants in a 4x4 tent,

exhaust always taking fresh air into tent.

temp/rh controller has tent at 77 degrees and 60 or so rh.

Spider sf7000 at 60% power for now about 30 inches above plants

Ocean forest soil 5 gallons pots

Water ph 6-6.2 going into plants.

I started nitrogen right before flower and now adding potassium.. foxfire trio nutes, trying not to go heavy because I over nuted last grow.

I mix nutes Into 5 gallons of water (two feedings per plant)
I’ve only added 3 tsp grow big, and just switched to same amount of tiger bloom.

I’m concerned about this browning on leaves any advise or opinions? Thanks so much

Could be from brushing against your scrog screen if there’s a fan blowing on them. Not sure but that’s all I got.

I was actually just reading could be burn from fan and rubbing, plants look healthy otherwise

Hey guys question on feeding I don’t think I was giving enough nutes. 4th week of flowering now. to get to over 1,000 ppm I had to add a ton of tiger bloom to 5 gallons of water.. 2 feedings worth.

Do these numbers look ok or am I gonna over nute ??

Runoff was around 600 ppm that I read today, that’s runoff from last feeding 5 days ago
