Urgent help needed please

[manfredo]

On my last grow I only fed once a day and they were fine all the way, they were nice and green and healthy until the last day of flower. And two of my plants right now are green and healthy and they are only fed once a day. But the other 2 plants are messed up and they have been treated the same as the two good ones. I understand I need to feed more regularly but I don't think that is the issue here? I've been known to be wrong and I don't mind being wrong. But why are two of my plants looking decent and the other two looked totally fucked?

It could be a bad pheno but that wouldn't explain the burning....If that's what it was.

Why not try flushing the 2 small plants real good...could be salt buildup. Like flush a few gallons of clear water through each. Can't hurt.

Leaf edges are raised in at least one picture. What’s the actual leaf surface temperature on these?

It varies from 26c to 28c. I'm pushing them to the limit that's why the leaves are slightly taco'ing

I've been growing for the last 10 years so I'm definitely not new to this

What do you guys think about salt build up?? Could that be a factor? I'm wondering for myself too!

I just don't understand how two plants can look pretty nice, while the other two are burning up and giving me problems all the time and barely growing

I'm feeding until run off daily so I don't think there could be a massive build up of salts?

Mate, if he’s getting 0.5 ec runoff, where is this magical salt buildup we are talking about? Ive had runoff measure at 3.0ec and my plants won’t look like that

That's why I always thought it was a potassium deficiency instead of a nute burn issue, but the other two plants are fine with the EC run off being low so I'm totally confused. It's a very confusing strain to grow that's for sure.

Runoff at 3.0 ec?? In coco? Wow!!

I am new to coco but never heard of such a high ec....I just figured if he was only watering once a day there could be salt build up if they weren't being watered to runoff, but he says they are.

Yeah what's really weird is 2 of them look great, and it's the same routine you normally use. It is a mystery for sure!

Is this your first time using this brand nute? I remember reading you switched at some point.

I switched nutrient line because they weren't doing very good and I thought A&B for hard water would work better. I'm still using A&B but it's by a different brand. They both work good because two of the plants are looking decent so I haven't got a clue what's going on dude

So obviously you don’t need help then. Just running this by for the hell of it I assume.

edit add: not trying to be a smartass. I sense your frustration. Just trying to cover symptoms seen.

Sorry mate, it's my fault. I should have listened to you from the beginning. I've lowered my EC to 1.0 and they have stopped burning up. I haven't grown for a good few years so I'm kind of out of touch lol

Any ideas what's wrong with this leaves guys? It's mostly on the newer growth @manfredo @dwc420letsgo @hotrodharley

 

[rkymtnman]

your new growth is showing nute burn. did you fix that yet? what pH are you feeding at?

Yeah I lowered the EC and fixed the nute burn issue, my PH is 6.0 dude

 

[rkymtnman]

my PH is 6.0 dude

is it always at 6 exactly? maybe try to let it fluctuate b/t 5.8 and 6.5 in coco.

Yeah it's always at 6.0 PH dude, so should I try 5.8 PH tomorrow?

 

[rkymtnman]

Yeah it's always at 6.0 PH dude, so should I try 5.8 PH tomorrow?

does it stay at 6 because you have a pH doser?

i like letting my coco free range from mid 5 to mid 6
