My auto Northern Light ladies

[aiio0nweed]

Hello, 1st time grower here, and its a blast.

But, i start to worry a bit since the edges of the leaves curl up.
Not allot, but i like to stay ahead of the problem.

I did somme googling myself and found it might be the light hanging to close to them.
So i moved the LED up about 1ft. (now 2ft)
Has anyone else seen this before? and what did you do?

some extra info: humidity hangs around 50-55% temp is always around 27°c/30°c
i give them around .5L water every 2 days (depends how dry the ground feels)

Agreed... too close to light

called tacoo .
usually heat / light / RH problem .
mostly heat by light beind to close ; when the leaf is 'tacooing' its protecting it self from the heat ( if im not mistaken ! )
and slowing grow rate ; which can be deadly to auto's

I don't think it's the light being too close, dosent seem like a very bright light. How many watts is it? Also notice how your plants are growing inwards? They are growing towards the light. My guess would be low humidity. Do you have a gauge? If it's above 50% then yes it's the light being to close. But you should have no problems at all with a led light being a foot away. And it's not even directly over the plants, it's in between them.

Minimum distance for led lights is 16 to 18 inches, 12 inches is just a wee bit too close.

depends on the light, hell I keep mine a foot away and they are pretty powerful. No issues

Its an Apollo 4 180w, and the humidity is around 50-55% atm

does this look like under or overwatering to you guys? i give 0.5L water / 2days

 

[Old Hippy 127]

You need wet/dry cycles. A schedule like you described is not the best way to go. Read the post "How to water a potted plant." Search for it. Can't tell much by the picture, but from what you said, I was guess you are watering too often. Get a rapidtest moisture meter and check the moisture profile in your pots. See a post titled "Watering made easy," in the growers lounge. That's how I do it...

Coco should never be allowed to dry out, it locks salts to the fibers and kills the roots.

I water almost the same for coco and dirt with one difference, with dirt I poke a finger in the top and if the dirt is still moist I DO NOT water. With both I lift the pot and gauge the weight of the root ball, I DO NOT water a bottom heavy pot.

I lift the pots daily, and poke a finger in if using dirt, if the pot feels lighter in coco than a freshly watered pot or the pot feels lighter and is dusty dry on the top for dirt, then I water again.

Impossible to tell if it looks over watered or underwatered because they will look the same. You will get the watering down, it comes with time. Depending on how big your plant is, like me, I only feed about a 1-5 gallon every 2-3 days.

 

[aiio0nweed]

Alright. so clearly i was overwatering and the post about "How to water a potted plant." cleared allot up for me. cheers!

now if i may ask another question. there are these little flies on the soil and i was wondering if they can hurt my plants?
And if so whats the safest way to get rid of them without hurting the plants?

thank you for all the info

get some westland resolva it works a treat, i sprayed my plants and they went within 48hrs!

 

[Why Doe]

Yep those are fungus gnats and are a pain in the ass to get rid of. They come from the fertilizer, lot of soil mixes have them. It's not the gnats that are the problem it's the eggs they lay in the soil that turn into larva and eat the roots. I don't like using foliar spray and chemical stuff that can effect and harm buds. So I used mosquito dunks, yellow fly paper, and sand on top of the soil. Prevents them from laying eggs and when they try and come out of it it shreds them like glass.

an update picture

now the bottom leaves are getting lighter in color...

is this normal or did i overfeed them?

 

[Why Doe]

They look normal. You would know if you overfed because the tips of the leaves would be burnt

 

[aiio0nweed]

the leaves on the bottom are allot lighter green then the top leaves.

 

[Why Doe]

Give it a small dose of some base nutes with nitrogen.
