Help diagnosing problems with plants, pictures. Tips curling under, edges raising up.

I'm having a couple problems right now. The biggest problem is the smaller plant has root aphids and has severe root damage from them. I have done two cycles of azamax but there are some that can fly now. The only thing I can do now to be sure to get rid of them all is flush the tent with 5000 PPM co2 for 20 minutes for 4 cycles.

Second problem is with the big plant. The leaf tips are curling under but feel moist. The leaf edges are raising up and some edges are brown from what looks like nute burn. I have been running 600 PPM nutes at a constant pH of 5.6 to 5.8

Last problem is with the seedlings. They are yellowing and some of the leaves are deformed. The nutrients start out at 100PPM but quickly rise to above 300 within a few days. How can I fix this? The hydroton was thoroughly rinsed before using it and then flushed with ph'ed water. I am using RO 0PPM water too.

I have one 600W MH light going 24/7 that draws fresh air to cool the bulb and then vents out. The carbon filter creates negative pressure to draw in fresh air. I have one AirKing 6" fan for circulation. I use General Hydroponics FloraNova nutes with CaliMagic. Fresh nutrient reservoir with 600PPM nutes and balanced to 5.8 feeds two waterfarm units that have been retrofitted with float valves. This keeps a small amount of nutrients in the reservoir and brings in fresh nutrients when the level drops.

Any help is appreciated!

How close is your light?? Looks ike heat stress, is it just the top leaves curling up at the edges?

its pretty far, I'd say 20" at least

lookin at your plant closer, curling edges are throughout the plant, maybe not heat stress unless this has been going on for a while.

anyone else?

how are the roots looking

oh nevermind...

its definitely from root stress then since u already said u had bugs

the bigger plant's roots are fine. only the small plant has brown roots. will these recover or should I just scrap em?

Honestly bro....scrap'em. I know it's HARD as all hell, but this aphid problem is going to drive you fuckin' crazy. I personally would clean house at this point. If Azamax isn't helping I'd just clear the plants out, fog the whole thing and start over. But that's my personality. I KNOW how long it will be then until I get bud, fighting the good fight could go on for weeks or months and then you end up deciding to scrap it all and you've just wasted all that time.

The "small" plant (I assume that these are your mothers?) looks like it has root problems. It almost looks like overwatering, but I'm assuming you have watering on lockdown so for some other reason the roots are acting as if they do not have access to oxygen.

Good luck whatever you do, a fogger may help without having to scrap them, but you'll have to do it a few times a couple of weeks apart from each other to kill everything.
