Talk and Skinny

I’ve got tall skinny plants that are starting to get me worried. This is my fourth indoor grow and the only thing that I have changed is the seed, not the seed vendor. I got my seeds from Robert Bergman. This strain is banana kush auto flower. All the plants look pretty much the same for the first three weeks but now they’re starting to develop like little freaks. Same soil, same nutrient, same grow light, same distance from the light, watching my temp and humidity levels. Doing everything similar to my first three grows so I’m confused. The plants just look weird, but then again I’ve never had super super big buds. But I don’t think this is how they start. This is the end of six weeks in the soil. Any ideas?

When I start doing searches it keeps taking me to Foxtailing but that’s for mature plants and these might be too young for that. I have five plants in the tent, three seem to be getting tall and skinny, the other two are shorter but it looks like the branches are starting to develop similar to the other three plants. Any help would be appreciated


Forgot to mention, I performed LST using metal stakes . Seemed harmless, Was actually way easier to use than tying them down. I think my LST for this grow was a success.

I’ve been using the metal staple looking pins for mine as well. I use wire cutters to cut them in half and then bend the part I cut into a hook so I can have a bunch of them.

It’s very possible that particular strain is just lengthy like that. I’m a new grower myself but other than genetics and light distancing I don’t know many common factors that cause it. We’re your first ones indicas? Bc as I understand it sativa’s tend to be more lengthy on the internodal spacing.

Do you know if the strain is an F1, F2, F3, or any type of reference as to how stable the genetics are?

Website really doesn’t give mention to F1, F2, F3. I do know they’re feminized, and auto flower. I started six seeds and five survived. And they were not cheap!

This will help everyone diagnose your problems!!

  1. Indoor or outdoor? - size of grow?
  2. Otigin of seeds?
  3. Regular, feminized, or autoflower?
  4. Origin of water. PH, EC/TDS of source water?
  5. PH and TDS/EC of if mixed solution?
  6. Grow method? Soil, Soil-less, Coco, Hydro, Aquaponics. Please explain.
  7. Nutrients or fertilizer system used.
  8. What typr of lighting are you using? LED, HID (MH, CMH, HPS), or Fluorescents? Please elaborate.
  9. What are the temps in your growspce? Day / Night?
  10. What is the RH = relative humidity in your growspace? Day / Night?
  11. AC, Humidifier, De-humidifier?
  12. Do you have a Ventilation system? Size? 4", 6"?
  13. Co2 Yes / No?
  14. How long have you been growing?
  15. What budget have you set in order to grow successfully?
  16. If you grow hydro, then please explain your hydro method. DWC, R-DWC, Ebb and Flow, Or; Other? Other?
  1. Indoor
  2. ILGM
  3. Autoflowr
  4. Faucet. Use PH down / up.
  5. 6.8
  6. Soil, Fox Farms Happy Frog
  7. Hydroponics Flora 051,216,501
  8. TSW2000 300 watts led
  9. On 77 off 68
  10. Using VPD chart - within acceptable ranges
  11. As needed. Heated room, have both.
  12. Yes .6
  13. No co2
  14. Two years, this is grow number 4. AK47 photo, Bruce Banner autoflower twice. This is banana kush, feminized autoflower.
  15. Hobby, willing to spend what’s needed.
    16 . No hydro

I also use Fish Shit soil conditioner, molasses, and Mammoth Bloom enhancer. All used and measured as recommended. Hope this helps.

Looking good Growmie and they’ll stretch a different rates. Kind of like kids in the same family…some a little taller than others. I would ask what your lighting DLI is :love_you_gesture:


i got some Zkittles doing that, last grow i had one lemon haze do it.

DLI is 18 on, 6 off

That’s your lighting schedule Growmie, DLI is daily lighting integral. What height and intensity if you don’t have a meter to read DLI :love_you_gesture:

No meter. Keeping top of canopy 18-20” away. Lights intensity is 100%. Should I back it off? BTW, what to buy to provide that info? Is it required?

I use the photone app to keep lights adjusted . Without a light measurement dli is just a chart to look at

I’m not seeing any issues here. They look like they’ve done their preflower stretch and here they are showing you gorgeous hedgehogs.

Cannabis is ugly. :rofl: it’s a fact. We just find it pretty because we know what we’re looking at.

This is probably why you never get outstanding massive buds. 300w is okay - it ain’t enough to flower out more than a 2x3, maybe a 3x3 at max output. I have my own thoughts about Mars Hydro for lighting, but that’s an aside.

If your lights aren’t adequate, you’ll see lots of stretch (lots of space between nodes), but more importantly your plant can only do so much.

Stop stripping fan leaves, and leave as many of those solar panels on her as possible, so you can make sure she gets the most use out of the light you are able to provide to her. Without leaves, she can’t photosynthesize, can’t make the energy and thus cannot build bigger buds.

try to be patient, and allow her to grow. She’ll get there - it’s just our job to help along the way.


Thanks. I never had it stretch like that. I usually start stripping the fan leaves, but this grow I decided to let it be. So in addition to the stretch you are seeing, it really isn’t producing many fan leaves. Not sure how to bring in another panel, I have a 4x4, so not sure if it would fit in there. Might be time to invest in something more powerful. Feel cheated. Bought a kit from Mars Hydro. I would have expected the light to be sufficient for the size tent it was paired with. Suggestions for lights?


Yeah, unfortunately that’s one of their dumb “gotcha!”s about tent kits. Very much one of the reasons I’m not their biggest fan.

Supplemental light that would probably fit alongside the TSW is a Green Beams (green-beams[dot]com) - the 240w would help supplement your existing light without being a total lighting overhaul. I have a 240w and for the price it’s a beast. I got mine for $170, no beef with it at all.

A good re-do light is going to be any of the Diablo board lights from Horticulture Lighting Group (or HLG for the shorthand around here). I have the 650R refurbished and can’t speak higher praises.

The Scorpion Diablo refurbished is $750 on sale (25% off all the HLG Lamps right now on their site). The 650R refurbished is about $570 on sale. So they’re not a cheap investment but either one is more than adequate to flower out your 4x4 without a need to ever upgrade again.


This is an ongoing ‘thing’ that I just don’t get.

Plants use leaves to convert nutrients and light into usable sugars which then produces flowers. Removing them only reduces the plants’ ability to do it’s job. The only real caveat is if you have more than adequate light levels (and I don’t believe you do) you can remove, selectively once plant is past it’s stretch. The only other reason to remove leaves is for the health of the plant.


Good to know. I am trying my best to leave them alone. I have been tucking the larger ones on the bottom. I am leaving the top ones alone.

Thanks. I will have to take a look at the lights you mentioned. Hard to imagine how much brighter it can get. Are there any enhancers that might fatten these skinny branches in the meantime?

Monosilicic acid would be my suggestion. Alchemist Stout MSA is what I know off the top of my head.

Any other Silica supplement would also work, but my thought behind the MSA is that it’s fast acting. Normal silica products (potassium silicate) are a good source of silica but they aren’t readily bioavailable. They rely on microbes in your root zone to break the potassium silicate down into silicic acid.


I am a retired accountant. I have to say that some of your answers are way beyond my comprehension. I will Growing has been a great new hobby, like a mini science project.

I do supplement my hydro flora products with fish shit, molasses, and mammoth using the recommended amounts.

I keep notes, but nothing like the grow journals that are out there. But I am in my office (grow room) when I first wake up. Lights out at 830 am. In the office when they go on, and in there sampling previous crops later in the evening before it starts all over again.

Your time is appreciated!
