So I've got 5 plants under a scrog I plan on adding a second screen under a spider farmer 4000

They are in coco and perlite still in veg mostly filled the screen I've had a few problems with these plants they are wedding cake clones had low temp problems and pest problems I've fixed them issues now

but my ph meter has needed to be calibrated for the past 2 week and will finally be getting my buffer solution soon so been holding back switching to flower

The screen is mostly filled now I was planning on thinning out and tiny branches and any where there's multiple in one square if can't move to another hole then switch to flower also was thinking if I can't pull the branches back under to another hole or suppercrop or tie down in the first 2 week of stretch then to just top them and then if I get 2 tops growing then just snip one of them so don't get weird growth when budding anyone have any advice also if you want to know more just ask these pics are about a week old so there's not many gaps left now

Uhm.
So for starts.... The plants are looking rough. You should look into your feed and ph.
Why would you leave all the bottom growth on? In a scrog the point is to build an even canopy and remove everything underneath the screen.
Those squares are tiny, and if you're filling each square with a branch you're gona have a really packed area that won't let much light through. So your tops will be ok and the rest will be underlit. Also, when you plumb, you never run a smaller line into a bigger line. It's always bigger line to smaller line for pressure.

Yes my ph might of been a little off just waiting on the buffer solution then can see if I have a problem there or if its the feed also my other clones look much greener so not sure if the led light makes them look worse the holes are 2x2 and the extra screen I will be adding is 4x4 inch and yes I have removed some growth from underneath and will be removing more also thanks about the feed lines I did have a problem with 1 plant not getting enough water coming through I've just been hand watering them because I had a leak but until I can redo it my solution was to water the plant that was struggling to get the pressure first because I have a reservoir sitting at about 5ft then separate taps for each plant and also a tap that controls all plants so my idea is to water the plant with low pressure first because the higher volume of water will help

That net doesn’t look the most user friendly when it comes to harvest time, but that’s not a big concern till then. Also I usually have the net lower to train the plants, where it’s at it’s really more of a trellis for support than training. All in all it will work fine, once she stretches a bit above the net lollipop the lower branches, get rid of everything that won’t reach the canopy.

Yes I plan to only keep what's above the first net and add the second net maybe first or second week of flower

If that grow hasn't been flipped to 12/12 a second screen or trellis is a likely necessity. Looks well planned out, but allowed to get out of hand.

Yes I'm going to add another screen with 4x4 inch holes and I had problems so didn't want to flip until sorted ill weed out any thin branches too

What's your temps, and what % are u running the light at
If it were me, and I had 5-6 plants I'd run 1/2" tube off the pump, with those smaller 1/4" splitters feeding the pots with the 1/4" tube on a emitter of sorts. Like drippers or sprinklers. I'll grab a shot of my small time irrigation setup for reference
The manifold you're running would require some decent amount of psi to feed each line equally. Otherwise, underpowered, it'll go into the easiest route avoiding the other ports giving you low/no output on some, and higher output on others. Rule of thumb for plumbing, always decrease the pipe diameter to get higher psi. That's why you have 3/4" run into your house and 1/2" copper lines. 3/4" gives you the volume, and reducing it into 1/2" gives you more equal pressure.

One thing I've noted is that while in veg, the lights can be turned WAY down. Like shockingly low. When you run it high power, they can't handle it. Try turning it down to like 25%. I know it seems like not enough, but give them a few days to recover, then SLOWLY increase the % by 5% each day, until you notice them drooping slightly by the end of the day. That means they are getting as much light as they can use. Then dial it back 5% once they start to flower, you should be getting closer to 60-70% power and can then turn it up higher for flowering. That's what I've found at least. My plants used to look like that too, when I had cool temps and too strong of a LED.
Also 65 at night is too cool. You're gona want to bring that temp up a bit.

They should be 'palms out'.

Also thanks for advice on the irrigation i was just watering one plant at a time but I'll definitely love to see your setup I thought having the res high up and a decent volume of water would suffice was only my first time trying to set something up so I can water each plant individually or all together and used what I had on hand I just drilled holes into the hose because the sprayer valves I got was rubbish

Np,. I'm going into the 'dungeon' in a few mins after my coffee and dab break and I'll grab you some pics. You can also check out my thread on orbit irrigation. I think it's still on the main page. It's a more advanced version of the small one I'll show you

Heat mats help, panel heaters or oil filled rads. Can get one at Walmart for 30$. I hang mine on chains

I run 2 400gph amazon special pumps on a loop. One pump per end.... So I get an even flow in all the lines

Then the 1/2" tube splits into 2, 1/4" lines per pot and continues running around the tent
