Leaves dieing during flowering???

Yeah, I mean check under the hydroton.

PH is a possibility, so is overfeeding, but I'd check the roots first. Then PH, if its overfeeding it will fix itself while its on the rinse cycle this week. I'm not completely sure the difference between food grade 202 and peroxide. I've always used peroxide, works wonders for me. Doesn't sound like an O2 problem, even if your stones were a little clogged, clearly there is enough air in the line.

Sorry I couldn't help more, but thats typically my goto move in this scenario

35% is only listed as/for food grade as far as I know, and is the same thing as normal peroxide just way stronger so you dont have to use as much and it lasts longer then normal houseshold (3% peroxide) from my understanding, if im wrong someone can correct me but most sites ive read said 35% does a better job, I just dont know being my first grow and first time using it any input would be greatly appreciated, but thanks alot man for your replies they have helped a lot!!!

P.S. Ill be checking under the hydronton and letting you know when lights are on, I got 3 1/2 hours to go, just need to know how much 35% h202 I should add to my res and if its safe to add with my current nutrients and the hygrozyme, thanks again.

Ok I finally found the dosing after countless research its 8ml per gallon...next question is it safe to add the h202 straight to my res? Or should I mix it with some water first?

Something else ive done that was different I just thought about was adding the liquid koolbloom, did it last res change and on the change I did this morning, other then that nothing else changed.

Couple pictures of the roots, from what I seen the roots didnt look or feel slimey under the hydronton sry for sucky pictures. And the roots in the bucket didn't either. They are lil red/brownish from the micro, but they seem fine, I added about 15ml of h202 to see what happens. Gonna pick up some subculture B and sm-90 tomaro to be safe, can I use all these things together? My 3 part nutes, hygrozyme, 35% h202 and the 2 I just listed? But from the pictures I have what do yall think? What other things could be the cause for my issues? Will update after I see how the h202 does, thanks.

Anybody have any idea?

[low_rdr]

wait a few days to see the plants reaction

You don't wanna use subculture and hygrozyme or oxide because they will counteract each other. Also believe the hygozyme has h202 in it so be careful if using microbes because they counter wasting $

Ive noticed since the change my plants have smelled way more potent but seems still having a problem....roots like perfect im starting to wonder if there is a salt buildup? Maybe getting locked out or something....how exactly do I flush a dwc system...do I just pour clean eater through the top and let it drain? If so how much/how long? Can someone give me detailed info plz ive tried to research and some of the sites dont give you details....hoping after I flush it helps....thx
