If you look back up in the post I have my whole history with pics it started in flower you can see the progress. I just don't know what I should do.

1.5 ec was too high. try getting it down to 1.0 and use that for a bit. too much nitrogen is being used which is causing the dark green color and leaf tip death. I know you were told to keep up the nitrogen in the first two weeks of flower, but I think maybe just go with the micro and flower fert as the micro has quite a bit of nitrogen in it. are you following some kind of ferting schedule, like so many mls per liter of water?

When it was 1.5 EC it was still early into veg. By the pictures there was no yellowing yet. So I lowered the EC to 1.2 the next nute change. I'm following the general hydro schedule based on the amount of water I'm using.

I still think it's over ferted because of such dark green leaf color and leaf tip death. You do what you think is best.

I went back in there today and it looks like the new growth tips are brown and wilted. I have been at 1.0 - 1.1 EC for about 4 weeks now.
I had them at 1.5 EC back in end of May. So I corrected the EC issue I feel. Unless i should go lower than 1.0.
Thanks for the help

I think if this were my grow, I would lower the ec even more because of the color indicating over ferting. like maybe 0.7 or so. not really sure on this because I understand ppm, not ec and different conversion charts gives different answers on what ec corresponds to what ppm. I've heard of people using low, like 600 ppm with success, but I don't know what ec that amounts to right now. I would lower it if only to see what will happen as an experiement. what you know right now is that the nutrient level isn't right. too much nitrogen causes that dark green color and leaf tip death.

I came to the same conclusion as you. So I opened up my drain and let out some water and set my RO water to slowly add enough to get to .700 EC. I think your right on the nute burn.

ok, come back and post is this thread later as to what's been done and the outcome.

I made the change two days ago. Came back in today and it seems like they are not growing or doing much..... Color doesnt seem to get more yellow, just stay the same so far. Ill keep updating. I still only plan to keep the PH at 6.0 and the nutes at .700 EC and let them chill for a bit.

Updates would be appreciated. I have a outdoor grow and have a similar issue at about 18 weeks veg now. Using DNF grow nutes at a medium strength dosage. Plant doesn't seem to be growing a whole lot in height. Leaves are taco'd and growing in sideways...
Any help is appreciated. Thanks and good luck on your grow!

I think you were spot on with your first thought on copper. Some strains are just prone to it. The problem is your giving them the micros which include copper and they are not taking it up, or they were not at the point you had it start. Now if its not getting worse (spreading to new leaves) the problem may be resolved, but they will stay that way, what is done cannot be undone, so to speak. It seems your ph was spot on so the issue would be if your roots were or are having a problems or just the strain your growing wants a lot more than your micros were providing.
If you run the strain again then try upping your micros if your roots are not to blame
Macros = N,P,K,Ca,S,Mg
Micros= Cl,B,,Fe,Mn,Zn,Cu(copper)Mo,Ni

That's a separate issue I think. Possibly heat stress, are you watering enough? If its heat stress from high temps and low humidity then adding kelp may help her deal with the heat as well as watering more. However there is also the chance it is a root problem if overwatered and has poor drainage. Its not the usual signs of overwatering. But still worth considering, only you will know if she is getting plenty of water and if the temps are very high.

Cheers! I am learning so many things about kelp lately.. It like a wonder substance it seems. Or at least helps in so many ways.

Mag def, I believe. Combined with general chlorosis from lack of nutrition or overwatering.

Dr who turned me to kelp. It goes in my soil mix and I add it to my water. Age old organics dry

Dont think its a lack of nutes... EC has been around 1.5 to 1.0 and its in DWC....... So not sure about the "Over Watering" is that possible in Hydro?

I dunno, but I'd imagine if it can be overwatered in soil, it can be overwatered in hydro? Despite hydro being about water? Mg def, then. And a little nitrogen.

the overwatering issue in soil takes place as it has little to do with water and more to do with the lack of oxygen. water-logged soil does not have any oxygen. dwc should use air pumps to put oxygen in the water.
