How can u tell when nute burn is over?

This is my first time growing ever. Four of my babies are about six weeks old. I'm using cutting edge solutions and at first I burnt them to shit. I kinda don't get it cuz they were fine at over 2.0 ec. The stems were a dark purple but the plants were fine. When I noticed the burn I flushed and lowered it to a 1.7. That didn't work so I lowered it to about a .9. They seem to like it but they are still showing sings of some minor burning. Here is a Vid believe it or not that clone is pulling through.

That's great you flushed... I use Compost tea it's the Bomb. I suggest u try it. I brew my own (www.bountea.com) I got a 5gallon kit years ago. It has improve my growing & the plants LOVE it! If you research compost teas... U will see the benefits! Brewing your own is cheaper & a better product if done correctly. Highly recommend. Peace & happying growing.

Sorry I didnt answer your question... You can tell by the plants overall signs of new growth, etc. I was explaining that the tea can be benefical in helping the plant plant recover.

I'm growing hydro though. My ph is at 5.8 and I have them watering for an hour then three hours off. I just want to make sure those bigger plants will be good to flower. Ya knaw wha I'm sayen cuz?

Oh sorry I can't be of any help in that area...I use soil For mother's & Soilless med. for flowering. I have friends that use hydro it's awesome. Goodluck bro, hopefully what you've done improve's your girls. And someone as some helpful advice.

Thanks man. I hope some one could tell me if they think these plants even have a chance. That's if they turn out to be females. They are a random assortment but not of low quality to say the least. I hope lol.
