I cannot figure out what the hell im doing wrong!! Please help

This WAS on my, right now, big ladies that are about to get harvested. I took clones from them and these are those cuttings. I just dont get it tho, they are all getting the same food, water, all of that due to being in a flood and drain system. But a few look way worse than the others. This... dead, curling leaf tips, older leaves CRAP! ughhhhh!!!!
GH Flora series nutes, Lucas Formula(I was doing the whole lineup on the bigger ladies and got the same crap). 8/16 micro/bloom + 10ml/gallon aquashield (just started this on last res change, was using H2o2 before) + 100ppm CaliMagic (put into water first before nutes)
400w MH
5x5 tent
exhaust pulling out
screens at bottom of tent open for intake air
2 oscillating fans. (moved one to stationary below the plants to move air, and it was pretty powerful so it was beating up the plants right next to it.)
ph 5.8-6.2
Feed three times a day
18/6 light
ppm should be around like 900
air temp - 73-78F RH - 60-75%
water res temp 68-69 give or take 1 or 2
Airstone in the res + i have a pump on 24/7 sucking from the bottom up to above the water line and dumping back in, to recirculate

I haven't done a Hydro in a WHILE but I remember trying to keep ppm during veg at around 500-700(and that was end of Veg, larg plants) unless the strain was asking for it, first thing, I'd lower the ppm?!?!?!

I don't think it is a deficiency due to underfeeding.

Where does the problem show first? (older leaves, new growth)

Is it localized to a particular spot in the room or is it random?

Older leaves for sure.
Its in more random areas than one in particular

Oh ya alsu using RO water

Looks like you could use some cal-mag if you're using RO water. It can be any brand just get some of that shit and get it going. I don't do hydro so there's my disclaimer.

Too much nutes or unbalanced PH

Putting 100ppm calimagic in before nutes.

So I have heard answers on both ends now more than a million times. I was told before that in dwc u didn't want it that strong because the roots are living in the solution 24/7. And that in a flood and drain it would be fine to have it up a lot higher. I need a consistent answer! Fml...

ok. in my opinion my dwc does that only when i use ro water. i use gh micro bloom and grow with a few additives and it stopped. i switched to tap water left out for a day or 2 and it seemed better to me. it looks like burn to me. maybe a def. also they look healthy. just because its dwc dont mean you have to reduce because its there all the time. you have good airstones in your buckets?

Haha, ok so i may be confusing some. These plants we're looking at here are in and Ebb and Grow system. 5 gallon buckets. Big res.

My previous ladies were in DWC. This was before I realized how much less work i would have to do with one res rather than a bunch of buckets. So I have asked questions on both systems.

When you say "dwc does that only when i use ro water." you mean the leaves looking like that?


And yes, i do use RO water for them. But before I bought the RO, i'm pretty sure they were doing the same exact thing, and in my mind i was thinking that it was the well water that was the problem. Got the RO, still have the issue.

On the same note, ur right, a lot of them and parts of each look real healthy. These pics were last week. As of last night, they look better.

I also just started introducing Aquashield. I was using H2o2 at first but I like that the Aquashield actually has benificail bacteria in it. The H2o2 Just kills ALL bacteria.. Maybe that Aqua will be the help it needs. Ill have to keep an eye on it now. I will let you guys know for sure what i find out.

Otherwise if anyone still has any thoughts, im all ears.


ThankS!!

Looks burnt to me. What is the ppm of your rez?? My guess is too hot!
