I was wondering if somebody can tell me what's wrong with my plants, I am on week 10 super lemon haze auto GHS strain. Been feeding advanced nutrients under 2 x 600 watt, 8 x 12L fabric pots and one 15L autopot (just trying it out) Soil.

Past few weeks they have been getting Bloom A and B 1.5ml per litre and last week switched from Big bud to Overdrive 1.5ml per litre aswell.

So they're on:
Cal-Mag 2.5ml per litre
B-52 1.5ml per litre
Bloom A n B 1.5ml per litre
Overdrive 1.5ml per litre

3 fans plus extractor fan so plenty of airflow.

16/8 light cycle
55% humidity
30 degrees Celsius day temps
The leaves at the top have turned yellow and crispy but the buds look and smell absolutely fine.

I just want to know why leaves have turned yellow and crispy?
Will the buds be fine after harvest?
How do I avoid/fix this issue?

Any help would be much appreciated, thanks in advance.rsz_20201013_175527.jpgrsz_20201013_175527.jpgrsz_20201013_175530.jpgrsz_120201013_1755300.jpgrsz_120201013_1755300.jpg

Light burn/too much heat and I suspect your overfeeding as well getting some nute burn. Do you know the EC of the fertilizer mix? Autos generally don't need a much more than 1EC.

I don't know the EC but PH has been on point the whole time, the buds seem absolutely fine. What do you think they will be like to smoke?

they can suffer from heat stress/light intensity. I was experiencing this and had to raise the light/ lower intensity and gradually bring her to like it.

Too much heat can affect the quality and weight of your buds. Try for mid to high 70's F for HPS lighting. What is the distance from the canopy to the lights? Lights being too close will hurt your buds too.

Major heat stress and nuted up to the max I'd say.

It's too late in flower to fix the issue now, it should have been spotted weeks and weeks ago and that is when you should have shouted out for a fix. These things do not happen overnight and it is obvious they have not had a good environment for a long time.

As for the smoke, I'd think it taste strong and harsh as feck due to the excess feed you have been giving.

All experience and I dare say you'll shout for a fix sooner.

I have the same size tent as you and 600watt HPS is ample.

Too much heat and too much P/K overfeeding.

You can see the foxtailing starting on the buds from the heat and the blotchy leaves down lower from overfeeding with P/K.

1200w in a 4x4 tent

No wonder they are burnt up and it's 100 deg in there

More like a 4x6. And it's 86f. But that's probably where his problems are coming from besides some over feeding.

He needs to move more air, or the route the air is taking. And maybe raise his lights. I run 1800+w in a 4x8 and can keep temps at 82f (hot days outside) or lower, normally 77-79f. And I do that without ac.

I think he needs to adjust his feeding too. Like to zero.

Yeah true and lights are just over 2 feet above plants

Yeah it did come on gradually tbf, however the buds have always looked fine and I've read on forums growers having 30 plus degrees Celsius day temps and still come out with top shelf bud as long as there is plenty of airflow and watered often enough. Just to add the light reflectors are cool tube with a pipe running through them connected to a carbon air filter and extractor fan.

Also there are 3 other plants in the same tent which are healthy green so I was a bit unsure as to what was going on but I think it's simply cos they are over fed. I have just began feeding them water only till harvest.

Cheers for the input.

Yeah I bought the full grow kit as a bundle bay6 tent, the lights are 2 feet above plants, I think you right about them being overfed. I always thought overfeeding would result in burnt tips which I didn't get so I didn't bother adjusting it.
