Hey guys seeing the new growth on my autoflowers and its looking a bit sad. The temps are in the low 80s under a 600w HPS. My light is about 30 inches away feeding them brewed teas. Do you think i fed a little too heavy and this is response from my tea. Maybe the light was too close and that's why I'm going to attach a few photos

Hey odieseal , your plants looking pretty damn healthy , careful with heat / radiant heat from a high pressure sodium. Maybe raise up a bit more for relief if you are feeling a bit too hot....
Teas are usually gentle and it looks like your mixes havent caused any harm yet , maybe a bit dry ?

Do you have a fan / air cooled hood on the hps ?

hey @dire wolf unfortunately i do not have a cooled hood for the hps just the old fashion wing hood. I do have an inline exhaust fan running and fan for return intake. Do you think that those leaves are looking like heat stress at all? I know knew growth in this early flowering stage can come out very thin. It's just been 5 years since my last grow and I feel like its all so new again.

I'd back off a bit on the feed too when you've been feeding have you been feeding to run off

I'd say you need to flush them properly if you have a tds meter ppm test what you put in and what's coming out

I think it's a little water logged with the way the leaf has recurved and not watering till run off can cause water build up , do you have your pots up off the tent floor .

I agree with above definitely need to flush properly when they dry a bit in my opinion

Yes flush till you have at least 10 percent run off as Needshelpguy said

Nice unsure what one I have but it was like 10-15$
I think mine was$ 7.50 I'm a cheap Irishman .....
i dug around a week or so ago and found my old one from years ago. battery was dead and i forgot about the meter since. Been running ok so far on feedings, but this is my first time using organics and i know it can take a bit longer for them to respond compared to salt based nutes. I think i just went a bit too heavy with the seabird guano and wormcastings the past 2 teas.
I also need to make sure im feeding to runoff. Still learning a lot these past few weeks being the first time in coco.
