Sooooo UV-a didn't completely prevent pests & fungal issues in your indoor grow.....................shocker!Im growing with organic soil (Biobizz), so nutrient burn is not that easy, but maybe because they had a phase with too less light.
Damn I'm getting quite unlucky so short before harvest I just found one suspicious leaf, when inspecting it, I found a bunch of spider mites and traces of powdery mildew. I counted about 10 spider mites on that leaf, but I can't find anywhere else. The powdery mildew are just traces, if I didn't knew how it looks like, I would not see that. Found only 1 other leaf with a few traces so far. And while inspecting a lot of leaves, I found a thripse. Only a single one. Damn. Everything is in such a early stage, I could possibly go a few more days without much damange, and the trichromes could really need that. But 3 threats? I guess I'm gonna have a long night and harvest them a little too early.
insects that exist under sun light thrive under uv too? omg!Sooooo UV-a didn't completely prevent pests & fungal issues in your indoor grow.....................shocker!
I cant say for sure but it kinda looks like the fade under our most over built light (about 2000 diodes per 1m2). The top leaves went from fading colors to very to super cripsy and dead in very little time and just burned off. It seems to happen to us when light is hitting the leaf from all angles, boards being very near. Not discounting that thereView attachment 4370089
The other side with the weak ones. Don't judge me by them, but they may are interessting anyway regarding the lights. I also want to note, I got them as cuttlings, where as the strong ones were from seeds. I did not get them super healthy.
It looks sad. Like this:

(thumbnails are enough ). It got harvested yesterday, while the hairs were already all orange, the trichromes just started turning brown (about 15%). They are very very compact buds, so I got still something to smoke
The interessting part is the burn it got. This plant didn't receive enough light from week 1-6 in flowering (panel was too weak for the bigger space and it got covered up from the bigger plants). The difference was already big so there was not much I could do.
After I got the High Lights, I wanted to burn them. Go full, no regrets (well I could not lose much here anyway).
That means going up from a space with 120w light (F Series) and alot covered from other plants, to 240w and nothing in the way anymore. And pretty close (top bud was like 10cm away)

Does it look different from heat or usual light burn? For me it kinda does, it could be rather a "sunburn" from the UV lights, but I didn't experience heat or light burn yet myself. But it did not start at the tips of the leaves, rather in the middle, getting crunchy pretty fast.
A side note: the very tip of the leaves showed some burn signs on all plants - specially the bigger ones. That for me was light burn, but in a amount that was fine. They all had pretty dark green leaves, as they had too much nutrients because they had too little light, but it started to decrease with the new lights. The burned tips stayed the same, so I was not worried.
I also noticed that the strong plants also got burn signs, mostly only on the part of the leaves that got damaged by the thripse earlier. These parts just weren't strong enough.
Overall it looks amazing. The amount of trichromes are really good. There are some concentrated areas where I was really scared that I got powdery mildew, but with help of a microscope I could verify that its all trichromes.
The smell is already super strong, even from the weak ones.
I'm rally looking forward for the next grow with more ideal setup from beginning.
We had some similar burn/crispyness on some top leafs under intense and enveloping light. I think it was associated with the fade, they first went red-purplish then just burnt. Buds stayed fine and got very chunky.View attachment 4370089

LOL! You'll never here me making that claim. But I will say this: a friend of mine is using a couple of High Lights in conjunction with HPS and recently had an outbreak of whitefly and they all flocked to the HPS and left the LED virtually alone. But that had less to do with the UV and more to do with the heat.Sooooo UV-a didn't completely prevent pests & fungal issues in your indoor grow.....................shocker!
I don't really get "fade". But then I don't flush.I cant say for sure but it kinda looks like the fade under our most over built light (about 2000 diodes per 1m2).

Exactly that. The top leaves and stronger on the leaves that got hit from both lights. While the buds stayed finde. Do you have some pictures?The top leaves went from fading colors to very to super cripsy and dead in very little time and just burned off.

If you're interested, search for "potassium deficiency" and you'll see leaves similar to yours. Not uncommon in the latter stages of flowering when the plant needs it most. It can either be a deficiency (not enough K), or can be locked out by salt build-up of other nutrients.Exactly that. The top leaves and stronger on the leaves that got hit from both lights.

I didn't realise these were a thing, but apparently yellow light insect repellers have been around since the 70s!On the subject of insects/bugs....
The Insect Repellent Device.
Has anyone seen these 'anti insect lights?'
Sez the insects just leave the area?
I don't know what the spectrum is or whether they work or what they cost so don't shoot the messenger lol

Lights are placed underneath the plant’s canopy to drive the insects to the top of the leaves.
The light prevents them from laying the eggs beneath… so they leave. Others just leave.
For spidermites and thrip too.
If we can find out the spectrum it could be diy-able
