Your lighting is going to fall short of what is needed to grow out and flower even 1 plant.

Here’s the topic you should go to school on.

I have very similar condition to you on two of mine also

I been told it could be a calcium or manganese deficiency but I haven’t had the nutes to test this yet lol or equipment (as on budget atm only just gone back to work due to outbreak) so I’m on very basic equipment, 2000w Chinese LED, desktop fan, vicks humidifier, compost, and autos from the vault, Fed tiny bit of tomato food couple weeks back on my glue gelato which has just started flower, which I think was the problem as it’s high in nitrogen also which has given her the dark shiny leaves, but she’s still been growing and still started flower so I’m staying optimistic atm lol this is my first ever attempt at indoor grows and want it to go right so bad lol! Any advice I get I’ll share with you buddy

This is more recent photos of them, biggest one is glue gelato, medium one is cosmic bomb and the smaller one is cream mandarine

The cosmic bomb one is the only one I’m doing LST on to get comparison in yields etc and experimenting, and the reason they by the window this morning In the photos is because I was hovering the cupboard they’re usually in and raising the light lol This next picture is my cupboard set up :laughing: pic is a couple weeks old that’s why the plants look a lot smaller than they actually are

  • What strain-auto flower amnesia haze, auto northern lights, auto blueberry
  • Method: happy frog soil. Highly suggested.* Vessels: small pot
    *indoor for vegetation stage
  • Light system show in photo
  • Temps; Day, Night (70?)
  • Humidity; Day, Night (No idea)
  • Ventilation system; Small fan
  • AC, Humidifier, De-humidifier, (No)
  • Co2; No

I have no fancy equipment to test everything.

I’m thinking it’s the lighting! The bulb is roughly 6 inches from the plant. I’m watering it with 2tbs on water a day With 18 hours of light and 6 hours of dark.

Think I’m going to switch to these lights.

Or maybe someone has a suggestion of a light to use for these first stages.

Have you been spraying them with something?

Not at all! I water them with a shot glass

You have done surprisingly well for what you are working with. That said; you can’t really do much with low power lights for cannabis indoors. For medium-tier lights you use the metric of 50 watts of draw from the wall, NOT the equivalent per square foot of grow area. (Average sunlight for example is around 200/square foot). Sorta.

Point being: you need to go to school on lights if you are going to grow weed indoors. Here’s a place to start:

You should start at the beginning and work through what you can; seriously.


So you think I’m over watering it :thinking:?. Nothing to do with lighting? Maybe if I sprayed them instead of poring the water in? I have both lights in now and moved the fluorescent light higher. I thought it might be burning the plant.

I’ve used a 125 watt cfl 6" away from sprouts and never burned any of them so not sure that’s the cause. I’m not a fan of spraying, so not suggesting that, just searching for a clue why your leaves are like that. You say you have no testing equipment, so any idea what the ph of the water is that you are using and what is your water source? Also any airflow between light and sprouts?

I do not know the ph level in the water. I’m getting it from my sink. Should I used distilled water? I have a small fan going.

Maybe it’s too cold? It doesn’t feel warmer then the temperature through out my apartment?

I think it’s getting worse :frowning:

I use a 2000w LED full spectrum for mine all three in compost no nutes as of yet and I’m having same issues, so I’m pretty certain it’s not a light issue

What’s your compost consist of? Could be having a reaction to your soil. It’s cannabis, not cannibals. Just a little pun there. Also heard on here that if you spray your leaves the lights can burn your leaves the water acts as a magnifying glass.

I’m not sure it’s literally Wilkinson’s own compost :joy:

If you have a ph meter check that on your soil… Should be no higher than 6.5 any higher and you will burn your plants. Solution: {as seen on here} To bring PH level down, Flush soil with water.

Is a PH meter water ok to check the soil with then?

And it’s ok to flush with just PH water right?

I use ph balanced soil, so I don’t use meters. But, I’m sure any ph tester can get the job done. See this ratio: Say your soil has ph of 7.5 you want to flush with water of ph 5.5 to bring soil down to 6.5, but if water is 6.5 ph or 6 ph, you will have to flush more times. Because you want your soil down to at least 6 or 6.5 ph, any higher, and you be burning your plants. I haven’t seen a ph flushing scale on forum yet, someone needs to make one. Just briefly heard it mentioned in passing, that’s another reason why it’s important to read the forum as much as you can… It’s loaded with real good info but it’s just spread out everywhere.
