Help!! Plants turned yellow overnight..

[Okietokie006]

So my temp in my 4x4 got down to 63 for two nights and all the leaves turned yellow fast! I’m growing in happy frog and have been feeding twice a week at 1/4 strength with tiger bloom and bloom, I’ve read to not feed in soil and I e read it’s ok at 1/4 strength, they looked good until now week 2 in flower.

She looks hungry

That’s not temp related. That’s malnutrition.
There’s nothing left in the soil by 2 weeks into flower.
Feed her quick before it’s too late.

Has absolutely nothing to do with the temps and everything to do with you not feeding it properly. It looks almost over the edge at this point. Hard to stop that kind of yellow and not gonna be able to bring much of it back now. Feed em and ride it out

1/4 is not doing anything to it.... its like you making a burger and only eating the ketchup

Lesson learned, I will just feed them properly and hope for the best, thanks!

You didnt notice a fade starting from the bottom up before? It was just suddenly yellow? That is indicative of a hell of a lot of stress if a whole plant goes yellow overnight. I’d expect the leaves to be drooping in some way also so that’s very strange. Full strength feed is what the plant in the picture needs

Actually full strength but half and half veg and flower is what I’d do. That plant has a ways and they do use up more nitrogen than you’d think

I did slowly notice it and thought I was actually over feeding them, I was told if I was using soil I wouldn’t need to feed much, I have two auto’s in flower as well that didn’t show these signs, but I understand every plant is different in what it needs, and I was out of town for a few days and had nobody around to help with them.

I just fed them full strength yesterday with Fox Farm Tiger bloom and big bloom, also added 2ml of cal mag per gallon and advanced nutrients big bud.
