Barney's LSD Autoflower: Nute burn?

Strain: Barney's Farm LSD Auto

Age: 9 weeks (entered the 10th week), in flowering

Growing medium: Soil, cca 4 gallons (15l)

Light setup: HPS lamp 250w put in a "wooden structure"
(no mylar), lamp is 12 inches (cca 30 cm) above the plant,
and receives, on average, 16 hours of light

This summer plant was outside a lot,
now it's exclusively inside.

3 weeks ago the plant looked just fine and
I decided to give it some nutrients
(2nd time, 8 days before that I gave it some nutrients for the first time)

So, 2 gallons of
water with nutrients (pHed) was given 3 weeks ago. That was
a mistake I think, because it looks like
a nute burn (I'd say nitrogen toxicity&maybe N lockout)
AND possibly something else too.
48h after I flushed it with water from the shower (not pHed)
because it showed signs of a nute burn (at that
time just a few burned tips on leaves).

Last week I gave it pHed tap water, 3 gallons cca
(12l).

As you can see on the pictures, almost ALL leaves are somewhat
affected, some are even dead by now, but surprisingly none of them
falled off yet, on their own, these really yellow ones (the worst ones) are crispy, you
can break the leaf, but the stalk is still firm. I'll cut most of the leaves.

Leaves have yellow and brown spots on them.
Midrib of the leafs (I believe that's the name of it) is affected, most
of the leaves have burned tips but some don't.

I'm worried because even pistils seem to have "burned tips".
I dunno, their tips look gray or kinda black even.
I'm just not satisfied with how pistils look and also
it looks like orange little ones came a little too early, although
the plant is in its 10th week and maybe that's just fine.

Also, you can see in one of the pictures how new leaves coming
out seem too small, they're slightly bent down and curled you see.
What's up with that?

Anyway, what did I do wrong (I presume nute burn and probably potentiated
with some other factors too) and what should I do?

Hey BRV,

Welcome to forums at 420 Magazine! Your plant looks great... do you know the breeders estimate on how long that takes to flower? Maybe look that up & post the info here.... I’m guessing that she has another week or so to go and she will be done. Yes she is showing some nute burn, rust and mobile nute deficiencies but should make it over the line. When the plant is still spitting out fresh pistils it’s still growing buds - but when the pistils change colors and recede....it’s time to cue the piano cuz the fat lady is about to sing.

your light spacing may be close... 250 is not a lot but 12 inches is kinda close

Do you you have a jewelers loupe or pocket microscope to view the trichs with? Very handy tool for trichs, mites and eggs about $12 at grow shops or online or usb version is about $30. I’ve got 12 buck cheapie see pics below

Hopefully more folks will stop by soon! please consider other opinions too

 
grey pistols is a sign of mould ,get a look ( might not be )
i think your soil could be better with good drainage you don't run into salt build up as quick ,( over fertilizing )
what is the soil ? or is it bagged compost, the compost will only feed for couple of weeks ,
autos will be slower outside , unless they get heaps of sunlight
did you spray the leaves at any time ?
 
No one knows heh? :D
Anyway, today I gave it 15l of pHed water and then gave it some nutes, mainly non-Nitrogen ones although I did put some little with nitrogen in it.

So, pistils have burnt tips I think, smell is weak and it's not really sticky. Sugar leaves don't have much sugar on them and it seems like it's not filled with trichs enough and buds aren't fat enough. Also, leaves, fan leaves&sugar leaves are partly yellow, from top to bottom!
See pictures. This doesn't look good to me... What do you think people?

:cheesygrinsmiley:
if your on your tenth week and this is an auto is never gonna grow much more , the leaves stay damaged the worst ones they don't change back to green , you just have to ride this out and let her finish ,
i would start making plans of things not to do and what to do next one , its a race against time with autos , ive had 3 stunted because i dropped the pots and broke them , they just went into flower mode , so at least here if you get a bud or two it something :)

soil good drainage , your from uk i can private message you a recipe ( water only ) should last the full auto grow

not the biggest plants in the world as i have to keep them low , but ill tell you whatever they get in the soil helps the smells and the hit is always beautiful, these autos are half way through NO nutes , just ph water 5.8 its a soilless mix
If i get these right through another few week , 3 or 4 ill give you the heads up, (its still a trail run) ( water only)

dirt cheap too , get it ? dirt cheap lol:cheesygrinsmiley:

It's just... I had this exact strain last year and it was beautiful. That one wasn't inside like this one, just out and it turned awesome.

This one doesn't smell (yet?), flowers look underdeveloped and dry (!), little or no trichs (it ain't frosty at all) and no fatness. I also just finished my Amnesia auto strain and she looked amazing compared to this one, albeit smaller.

Don't know. I'll just leave it be. Maybe I'll flush it once more.
