Thanks man, I ended up figuring out that I must have buildup as i saw it on the side of my watering table. So I watered for a day and a half with ph correct distilled water and wham ooo !!!!! leafs look good again. back to reg nutes and she never even flinched.....Thanks for the reply....this is my first grow ever and it all seems to be going real nice. I just put em into flower at 2.5 foot tall. I wonder if i'll hit 8 feet. I'll have to move my lights to the side if they get bigger...

I used distilled water as it has lots less dissolved solids compared to aged tap water....

Watering without feeding is generally as important as feeding unless you have your nutrient schedule down like 150%.

How are you liking the coco hydroton mix? I was thinking about switching from perlite to hydroton. Mostly because I hate dealing with a big ass bag of perlite.

the crushed coco shells seem cool, ya gotta rinse the heck out of it before ya use it.....lots of small dust and red bleed out....it holds a ton of water and nutes. I just changed 7 gallons of water and nutes.....forgot the tube going back to my res........7 gallons of water on the floor......fk....
