Wanted Deficiency or Light Burn

[kenseas7]

Hello there. I'm new to this forum as well as a newbie grower. On my fifth run but I've come across a concern with my Bruce Banner Auto. All was looking good then BAM! Brown and yellowing leaves forming on my buds Any ideas as to what this is?

that happened to me on my first indoor grow and it was too much nutrients. I mistook tip burn for Lack of nutes so doubled the nutrients and it locked out ,. i chucked it out but i then saw someone who said you can revive it with flushing

I've had it happen. I think k it's deficient, add nutes and find out it was lockout.

The plant could also be using up resources. Towards the end of flowering. But I'm fairly new as well lol.

There could be some light and/or heat stress. It might help to reduce the light slightly. That generally reduces stress. What VPD are you running?

Synthetic nutrients tend to be troublesome at this stage, as well. What type of nutrients are you using?

This late in the grow, it's tough to say what is natural senescence and what is a problem. I see a fair amount of edge curl and taco-ing, which suggests there might be more light than the plant can handle. Lots of burned tips suggest over-feeding.

Thank you for all the responses. This one has been on a very low dose of FF. My first grow came out looking amazing but it was destroyed in taste due to following the FF schedule. Way too strong! This is the only one I used FF on this time, only when I thought it needed it at a 1/4 strength if that. All organic on the other 3. @ArtfulCodger I do think it's light stress. Just raised it last night to 14" @100%. Also, I did try a stronger dose of nutes last night. @LoveGrowingIt My VPD is at 1.67 at the moment.

What media are you growing in? How often have you fed?

This one is soil. I've been using coco coir with way better results. It's got to be some kind of nute block, hopefully no disease. I just noticed a whole bunch of green mold on the bottom of the grow bag. I've seen some before but nothing like this. Ever seen?

That's too high. Young plants should be below 1.0. Here's a VPD chart that explains it well.

Do you have the grow bags on something that allows air flow across the bottom of the bag? That really helps. Plant "trivets" are available that do just that, but I've also seen some very creative DIY solutions.

I usually flip those plastic saucers upside down when I'm not feeding lol. I feel it works well. Bottom feeders possibly in the near future. Still learning but loving it! Thanks on the VPD.

If there's mold, it's too wet. Plant roots need oxygen. It's a big reason for using fabric pots. When the bottom of the pot is on a flat surface, water accumulates and there's no gas transfer with the atmosphere.

 

[kenseas7]

Trivets are a good idea. I've never had a problem with air-flow but I'll work on that.

What color are the trichs? I don't see hardly any
white hairs left on them. Prolly a stupid question,
but how close to being done are they? They don't
look like young plants. They aren't over ripe &
going backwards are they?

 

[kenseas7]

They both are at around day 65 from sprouting. The other is a Lemon Haze which I know is about done. Trichs on Haze are mostly cloudy and amber. I'll send pics. The one we're talking about, Bruce Banner, trichs are still quite clear. Still too many white pistols on BB I believe. I'll upload LH first

 

[kenseas7]

Here are some pics of the LH. The first Pic trichs from BB. Second trichs from LH

I don't believe there cooked jus a lil light burn. They look better all ready from raising the light
