Plant seems to be dying, should I flush? And if so, any tips?

You got a build up of salts in substrate with no run off. The run off helps rinse out used salts is why it is important. Your watering amounts are off.

Def showing tip burn so your getting a little hot on the nutes. The wilting can result from over watering or the vpd being off. Check your temp and humidity to make sure your in a good spot on a VPD chart. Then allot the plants to dryback they are definitely overwater or underwatered. If your watering often then it's over Watered man. It's super easy to do. I would let them dry half way then feed half strength nutes and water until runoff 20% so you can check runoff ppms and ph. After watering and feeding at half strength allow it to dry back half way before watering again to ensure your not over watering. Due this by pickup the containers up after watering until 20% runoff. Then feel how heavy. Then you wait until their half the weight before watering again. If your runoff is 300ppms over desired ppms or 300ppms over your input ppms then you are toxic and need to continue half strength doses or think about a flush. If it's much more then 300ppms over in your runoff then yes it needs a flush but you'll have to wait for it to dry before doing it.. flush with 2x or 3x the container size in water. Then at the end check runoff and if it ok follow it with half gallon of half strength nutes at the correct ph level. I would add some microbes if you don't already have them. Once per week add 2.5g per gallon of Rechage. This will help prevent lockouts in the future. It helps bit you can still cause a lockout if your over feed and don't water until runoff. Goodluck and Please consider me as the answer so I can be entered for a chance to win grower of the month contest I would really appreciate your support growmie 🙏 😃

Water these gals liberally to a decent run off. I suspect you have been watering far too little & the roots are suffering as a result. Check the ph of your run off too. Goodluck

Hi! You should let the soil dry before watering and have a runoff every time (it's help to keep the soil clean) But now, your plants need more root space. It's time to transplant to bigger pots. ^^ By the way, for a fist grow, I don't recommend training at all. You should remove your net and let your plant grow straight (and keep tortures tech for the next times). ^^

I would suggest flushing maybe it has a nutrition deficiency. What is the PH?
