Can someone please help if ithis nutrient burn or defficeny??

Hey guys I'm pretty new to all this so it would be great for someone with more knowledge to send me outnsome guides, it will be much appriciateed!

So I am growning 2 incredible bulk strains on coco
I am at week 6 flowering can I came across a issue that I want to stop before it gets worse.. here is some pics of what has happend to my crop

I'm using 2 600 watt lights one hps light one led
Room temp 24c
E.c. at 1.0
Ph at 6.3
Nutriens I feed are house and garden brand

Looks like nut burn to me.

yep, nute burn for quite a long time it looks like.

I thought so, but it just dosnt make sense to me i am under feeding them with nutrients probably by half of what the recommended chats says,

Can I still save those babies and if so how?

1 EC is not really underfeeding them. the "chart" wants you to use more nutes so you buy more nutes.

have you been giving them 20% runoff when you feed?

i would feed them with a nute solution of about 0.3 or 0.4EC with plenty of runoff for a few days. measure the EC of your runoff and i bet it's way higher than 1EC

So drop the ec levels much lower il give that a try hopefully it helps them to street out for the last 2 to 3 weeks

Well I flushed about a week ago and there was alot of ec built up, the run of was like over 3.2 ec so I think that's where the problem would started of.. only if I flushed a week or so early it would of helped alot..

Now my run of is at 1.0 ec same as what's in my tank but I think the damage is done..

Thanks for your help I much appriciated, so you recomend lowering the ec levels to 0.3 and water for longer period till there is about 20 percent run off?

yep. do that for maybe 2 or 3 days. measure your runoff. when it starts getting closer to 0.3, then you can slowly bump it back up. every time you feed, try to get 20% runoff.
but that 3.2 was your problem. that burnt the crap out of them.

The yellowing of leaf edges does look like a copper deficiency. Imbalances are to be expected when over fertilizing. Too much Phosphorus, for example, interferes with most of the micro nutrients.

Thank you kindly for taking the time and helping me out here buddy

I'm deffinetly try that and see how it goes
