outdoor grow ,in organic soil
nuts, A & B only until weekend past then cut mix in half and also added big bloom and calmag, all at half recommended .
PH 6.2/ 6.8
we also have had a couple of very hot days, 38 to 42 celius,100.4/ 107.6 fahrenheit, but I know its a nut problem, so do I do a flush, or something else, any help appreciated .
p.s. plants are wet due to its raining.
It kind of looks like something has been munching on it. I’m no expert, but I’ve never seen anything like that. What makes you so sure it’s the nutrients?
Hmm, are you sure you don’t have snails or slugs?
@raustin sure its not as the white you see makes sure there is none , its the brown marks I’m talking about
Sorry, I was just trying to find this in some charts.
Yeah, I understand what you mean, but it’s odd how the brown streaks are on the side of the leaf like that. I see there are also yellow leaves at the bottom. I wonder if it might be a fungus problem.
I think you should fill out a support ticket, luv. Sorry, maybe with more information we can figure it out.
Being a nutrient problem, rusty leaves come from iron being deficient, copper or zinc also being deficient as well as manganese deficient I’ll get a support ticket for you and help you out

Your problem is from heat stress. You did say it was 100.4. And 107.6 Degree’s
Here is a pic of heat stress your plants look the same way.

@garrigan62 is probably right, although my plants had the same weather and showed no signs of heat stress besides the one being sprayed for mites, and that was burn from the spray. I think it might be a bit early in the season to start giving it bloom nutes, is the plant actually flowering, or just in the pre flower stage? Mine have been pre flowering for a while and will continue for another month or more before properly flowering. I won’t start bloom nutes till then
@BondPacker same as your about 6 weeks been in pre flower but that one is an auto
@garrigan62,so should I stay with my feedings,and feed them there weekly nuts
Ya…you were giving them 1/2 strength anyway and your plants look very hood other than that stress burn from heat. If you know ahead of time when it’s going to get hot . Build something to shade them If you can from that hot sun.

Ah sorry mate didn’t realise it was an auto. Its possible the strain just can’t handle the heat like most others, maybe cause its an auto i don’t know, ive never grown one.
