Brittle dead leaves

[joebechill]

the top of my plants look okay but why are my leaves dying . cfl lights. 2.6 gallon pots early flower. very dry . crumbles in my hand like a dead leaf but still green.

Distance light is above plant?

Size of CFL, bulbs or big light like 315w

Heat and Rh in room?

 

[joebechill]

4 shitty 20w lights about a foot or so away from the top of the plants. i am a first time grower. 75f and 40% humidity. the plants are a little taller than i would have trained them to be with what i know now. i like the lights and i know walmart sells 100w lightbulbs in 4 packs . would that be way better than what i have now? i just got some random bulbs for when the plants were sprouting and used them the whole time.

 

[joebechill]

these are from 3 random seeds found throughout the years of smoking. all three became female i took about 8 clones so we will see how that goes

Do you have a fan blowing right on the lower part where the leaves are affected?

I was getting weird issues like this. Turns out my fan was windburning them!

The lighting you have sure looks inadequate to me. They are super lanky and stretched looking!

hmm i think it is windburn honestly. it’s blowing at the wall but then going directly to those leaves bouncing off the wall. that could totally be it. i turned my fan from 2 to 1 also . and do lights affect the thickness? do lights affect shorter lengths between nodes? i have 4 light bulbs that as you see lay sideways. are there any bulbs you prefer ? i want to invest in a light since ive invested in everything else . i just don’t know which one. i have a 2x4x5 feet tent

 

[joebechill]

i don’t know how else to set up this 7 inch fan but as you see it’s directly hitting the affected leaves

 

[joebechill]

also i have fabric pots being shipped. is it going to be a bitch to transplant? or should i just let these girls live in these pots until harvest.

Hmmm, are they flapping really hard? Diffused fan air shouldn’t be too bad on it.

 

[joebechill]

one last thing. i know i’m going everywhere with this thread but the dude at my local hydro store said “pros get about a gram a watt, hobbyist get about .5 a gram per watt” and then he said “if you grow with an led light then the temps need to be above 80f to get the full effects of led. compared to hps” but idk i would only invest in led for convenience and energy.

Lights will definitely affect plant height and node spacing. I’m growing sativa that’s known to be a taller strain. And my plants are at day 56 and only 18 inches tall. They are currently stretching for flower. So they will get taller.

they were flapping hard and they still have some flap to them going from 2 to 1 on my fan. do you think it could be another issue? i rarely water due to the pot and soil (miracle grow organic) hold a lot of water. i have since bought ocean forest soil but i haven’t used any of it yet

I don’t know what he is taking about. Not sure how increased temps would help LED. I’m no expert though. One thing I know for sure. There’s a lot of misinformation about leds.

I’m using 4 300w mars eco lights, and they are doing amazing so far.

that’s awesome to know thank you. what lights are you running if you don’t mind me asking. i think my stretchiest plant is sativa . and the other two seem like a hybrid. from what i have seen online that’s my guess

those look noicee. he said which i should have type out.. that led lights need higher temps to give the buds the desired thc , etc potency. like they can have the same yields and growth but somehow led lights react best to the plants with higher temps. it was the first i have heard it. he’s a 15 year grower. seems pretty old school. loves the sodium lights .

I’m running Mars eco 300w. There like under a hundred. And I love em!

That’s where I get my misinfo from. Guys who are Old school who think they are like LED from a decade ago.

As far as I know, ensuring that you have proper spectrum is what’s important for your lights. And that PAR rating is good enough to produce growth and flowering. A good LED will have nice blue and red spectrum, and not much green. The light manufacture will post their stats usually.

The Mars light I am using is full spectrum aside from UV. But from what I gather, adding UV may just marginally increase potency. So I may end up adding it, but at this point I have no plans!

thanks homie i looked online and checked them out they look nice! i have actually heard of mars “hydro” brand before and i see they go for 66$ at 300w . idk if there is any veg bloom switches though . idk how much that matters

hell yeah man ! i’m sure he could be misinformed on how new grow light led’s work . but that’s given me extra confidence in what i should be looking for. i think i am going to get 3 mars hydro 300 watts .. one for each plant. and i have heard UV lights help out! it’s crazy how many lights are out there. thank you so much dude !! ( i didn’t think this thred was going to lead me into buying 3 new grow lights but i’m stoked)
