Hello. I'm posting for a buddy that does not know how to operate computers worth a shit. I know most of the set up but not it all.

promix
advanced nutrients ph perfect
1/4-1/3 recommend dosage
two 1000 watt hps
temps in day are mid to low 70s
Temps at night high 60s low 70s
5 gallon pots
18-6 light schedule

I don't know his ppms
or ph
or humidity

these are the pics. Notice a few plants have the yellowing of the tips.

a few have random spots. They could be nutrients splashed on them while watering?

Mostly the lowers. Only a few plants. There are a few leaves here and there that are mid plant that kind of show it a little too.

It looks more then just not light reaching them imo......how far his 2 1000 (see why I think it's not lights?) But I can't answer the question be a use I am fairly new but def/tox is my hardest thing to grasp, I'm getting there but go to Google images and look at the tox/def chart, there are plenty

Lights are around 18-24" above tops. I was kind of thinking nitrogen deficiency because of the mild feedings?

Need to know what kind of nutes he is using and the ph. Those leaves are too dark to need more nutes, looks more like the start of lock out to me.

You don't have a deficiency. If anything you are overloading them. That super dark green color means back off on everything and feed with water.

Usually feed 2 times a week. Each plant gets around 1/2 gallon of water.

Grow, micro, bloom ph perfect
G- 30 ml per 10 gallon
M- 25 ml per 10 gallon
B - 15 ml per 10 gallon
voodoo juice -20 ml per 10 gallon
B52 - 20 ml per 10 gallon
great white roots - one scoop per 10 gallon

that is the veg nutes.

they are 4 weeks into veg from clone.

Just flipped 12/12

WOW 2 times a week is way to much for such young plants, I dont use the stuff but i think that line of nues are for hydro

He did say they were running 1/4 to 1/3 strength on the nutes, but I agree this looks more like overfeeding than deficiency, to me at least.
