Hi everyone, I’m beginner in growing,got 4 by 8 tent with 2 leds (mars hydro ts3000)the plants are on the 1 week veg(18hours on 6h off) wich was gorrila glue clones.the temperature is around 27c and humidity is around 60 I got 1 oscillating fan for now and the lamps hanging at 120cm above the plants because when they where lower the situation was even worse.the problem is that the leaves are yellowing with a bit of brown spots on some of the plants,can anyone help me with advice?would much appreciate.thanks

Looks like magnesium deficiency. Maybe need to up the feed strength.
What ec ppm are you feeding them.
@lukio uses coco so he'll know more than I

Holy Fuck that's a high EC/PPM out the tap. THIS is most likely the real issue. Your poms are way too high.
You need to go get RO water from the store, from the dispensers that are like $0.25-38 depending, or buy a filter system for $120 off Amaz0n. Mix your nutes, starting off with a clean slate, free of all potential BULLSHIT.
But first and foremost, you need to drench a good few gallons of just pure, 0PPM, RO water through your coco medium and flush out that build up of whatever I reckon is messin your girls up.

Can ya grab some A&B? you should imo

also, keep your Coco moist, stop spraying them and just top water. wait til the pots are light in weight but not dry until you water again. People on the forums will say you cant over water Coco, but you can if your roots aren't developed so careful with that
