Take a guess at whats wrong with these

[JB]

I've had leaves like that from too much N in flower. I worried about a re-veg at the time but had no light leaks.

As soon as I saw the pics I thought too much N, not 100% on that mind.

updated pics. Defo revegging isnt it.

will these go back to normal with a prune now? i have a couple mutant plants, any advice what to do with them?

I havent found any nanners and ive looked very hard at all areas.
15.c temp difference day and night 13.c & 28.c

seem to be doing better now after a flush for the last few days.

any advice much appreciated!! Or similar thing happened to you and what did you do about it?

I'm being dopey, but what do you mean by 300ml A and B?

Nitrogen toxicity (if the leaves were really dark green) (possibly overwatering) I'd guess but like others have said without better pictures of the colour of the leaves

What’s your water temperature ?Do you monitor it?
Cold roots will cause many problems some of which you are experiencing.
Needs to be 19/20 ideally.
13 air temp at night is too cold too and will cause problems.You really need to get that up for them to flourish.
Plants are overfertilised as the conditions are not ideal so they can’t process the food you are giving them.

I’d also check lights are actually 12/12 as looks like reveg but again could be caused by the cold.

Yeah, without knowing how many L's that's in and what EC it comes out at it's pretty useless.

Sounds like a lot of feed anyway.

The affected leaves won't go back to normal but if you get your feed dialed back you might still be alright although too much N in flower does hurt yield.

What's the EC of your feed?

I'd be trying to get that temp swing between night a day a bit smaller if I could too. Know it can be difficult but worth trying to tackle.

Thanks for replies.

Water temperature no i never look, it’s just always room temp. I never fill the tank full of freezing cold water ever, always some warm in there.


Yeah sorry. Those nutes are going into a 200l tank with an ec of 2.2ish
Very soft water here. Added canna boost and Riz.

Yep not been great with temp ths Year the weather temp is all over the place, it’s hard to keep the up with Mother Nature!

So the advice is to now cut off the extra leaves & narrow there temp with low Nutes?

Will the buds all be ok at the end? I’m surprised to not find any seeds. I’m hoping for the best

[JB]

Right EC 2.2 would be a massive amount of feed with hard water. With soft that's just ridiculous.

Most of us barely go much past EC 1.

My background is 0.6 and I've not gone beyond 1 yet on this grow. (so 0.4EC of feed)

No wonder you're leaves are like that.

I'd be halving that feed and seeing how I got on.

[onlymebro]

Wow really thats mad. i have a canna grow schedule and they recommend 2 - 2.2 for 4 weeks then 1.6 while they fatten! :S

I can see i need to water it down though which i have done now! the revegging is the biggest problem now. Theyve all got small balls all over them, no seeds inside though and odd looking vagina shaped leaves on the steps

anyone seen that before?
