Here is are some photos of about a week ago, buds obviously have gotten fatter, but you will be able to see the albino tips, bleaching tips. (Photo 1) These photos should give you an idea about the grow space i'm working with, originally this was only going to be a vegging space but i'm saving up for the flowering space. (Photo 2 & 3)
I have LST them down but I wont get anywhere near 18" due to the cabinet height. I noticed on the top of my buds they started looking bleached or albino, however the rest of my plant showed no signs of light stress, I used 2 cheap lux meters that i had lying around; under the 2 closest buds to the lights the readings where between 50,000 to 65,000 on 1 meter and the other one was between 60,000 to 80,000.
Cabinet size roughly 36" x 32"
Strain - CBD Hash Plant by seedsman - Choose for medical reasons and short growing plant that fits my grow space.
Any more info you guys need?

Some More Info:
This is my first grow, didn't do enough research about proper LED/COB/Samsung strips lights, I would do things differently if i had the chance again however I'm working with what I have. A proper Lighting solution will come in the future when i can afford it, just trying to get a few grows in first.
4" exhaust fan running 24/7
Tower fan inside cabinet running 24/7 for air circulation
2 x PC Fans for intake.
1 x 600w marshyrdo LED grow light (veg and bloom)
1 x 300w viper spectra LED grow light (bloom)
3 x temperature/RH meters. 2 inside cabinet, 1 outside cabinet, Temperature and Humidity control boxes are outside grow space with the sensors inside grow area at canopy height. I check them every time i walk in.
Temperature and humidity meters/switches that control my aircon unit in the same room as cabinet and dehumidifier to keep it a optimal levels.
Normal temperature controlled by aircon 75f
Normal humidity under 50% controlled by dehumidifier

I have PAR1200W Viperspectra sitting only 12-13" from some top buds and there is not even a single sign that they are burning from such an intense light. They look very happy, green leaves and growing fatter buds with more stem coverage than those that are sitting under 600W at a higher distance.
I do not have a PAR meter but I have a lux one. I believe at this distance it is 95 000 100 000 lux. The Sun on a clear day in my area gives about 100 000-115 000.
I am planning to raise all lights though just to get more coverage but it is not an easy task as I need to build a frame inside a tight cabinet above my grow to hung lights higher.
On the other hand there are a few in my cabinet that are not sitting under that 1200W LED. They have a 600W LED above them. Sure they get some angled light from 1200W as well but even combined with 600W direct light I believe it is still less light than directly under 1200W one. All these sitting under 600W are still behind in bud growing that those that are sitting under 1200W.
I am not questioning that you cannot bleach your plant with LED light being too close but based on my experience so far it is not as simple as "too close to a plant" especially with your light.

@PinPin What do you think can contribute to bleaching?
I did read a article about 'hash tips' but its very old and its debatable. (Photo 1, 2 & 3)
Since my LED are close I think it could be a possibility that the spectrum are not mixing correctly and the buds are being damaged because they are receiving to much of a certain spectrum. (But I'm only speculating) In general my plant is also very healthy in my opinion, just the very tops of the buds turned slightly white, but no plant burning and trichome look fine too.
Its a possible genetic thing to since the strain is a "Hash Plant" Strain.
I also can admit I'm not a experienced grower and I might be completely wrong about everything; i just try to do my research. But its nice to hear that you have your LED's that close with no problems. It wouldn't surprise me if the whole PAR range that mars hydro and Vipaspectra are half what they say, just like the watts. Thus meaning you could have it alot closer than more trust worthy tested brands, platinum led etc.
I have a similar problem like this thread only smaller tips.: https://www.420magazine.com/community/threads/albino-bud.180419/

I am on my second grow so I am not an experienced grower. I just looked at my situation and I do not see any relevance with supposed bleaching for yours while other things are a bit similar.
I have 2400W in LED(1x1200W and 2X 600W in a quite a small area(3 x 6), Actual grow area by the size of a canopy is only 2x4 plus one extra plant aside which doesn't have any light directly above it
Since I have not planned moving my plants from a tent to a cabinet well ahead I have all lights much closer than 24" to my plants. And I do not see anything close to these super white hairs. So my thinking when i replied was if my 1200W light for example did not do any harm to buds sitting 12" from them , how it could possible yours a few times less powerfull 300W and 600W doing so bad to yours even at 7" height.
Moreover I had some buds growing tall just a few days ago. They came to 1200W light even closer(about 8-9") and still I could not see any damage on them. I bent these buds to level a canopy but it was done purely for leveling, not because of any seen damage.
Not enough distance may be create a problem with spectrum mixing but then again why it has not happened to me yet.
If that mixing spectrum is indeed a problem for too close light then may be I just lucky to have 600W light sitting next only 3" apart from 1200W one and their light just being well mixed. The other 600W though sitting on the other side of 1200W and it hung at an angle away from a main canopy to give light some unplanned extra planed that I moved to a cabinet from outdoor. There are two plants under this angled 600W one and they are not getting any light from this 600W. They are growing under spreaded 1200W coming to them at an angle. So there is no extra spectrum mixing for these two plants and yet no bleaching on them.
May be start with looking at your plant top leaves. A couple of articles I have read about bleaching say that you will see signs of bleaching at top leaves. They should start showing some yellow colour. Is that what's happening to you or some hairs just abnormally white in colour?

You see less bleaching with white LEDs like cobs or strips or boards, although its possible to do it does seem less common depite the higher intensity.
Personally i think it has a bit to do with the UV diodes you get in those lights you have and a lot to do with the abscence of green in the spectrum, too much focus on reds and blues to beef up the par readings and keep cost down.
Only a theory mind!!
Looking at your pics you can pull all those colas further down and away from the centre which will lower the profile, increase the distance and allow more light lower down. You just need to dump the net, because its not serving much purpose at the moment, tie string with soft plant ties around the branches and pull an inch or two every day to spread that plant out. You can replace the net after if you think it will help keep them in psoition.
Adding up the true wattage 270ish and 130ish your about bang on for what you need from those types of LED for your full area, but your plants dont look to be filling the whole space by a long way so i would remove the smaller of the two lights and like i say spread those colas so they are almost horizontal. But do it over a week, a bit at a time so you dont damage or stress them.
Your doing well considering the circumstances.

@coreywebster Thanks for the reply, I already did LST a few days ago all a even wide canopy.
I thought it was a suitable true wattage for my grow space, you mentioned that my plants look small / not filling in. I just thought ill mention it is only 1 plant, a small strain because I was worried about the height and i only vegged for 5 weeks because; again I was worried about the height, I didn't know how big the plant would get since it was my first grow. Thought ill be on the safe side. Should 1 plant be bigger then this; I dont know?

I didnt say they were small, i said you have space around the plant so you have room to spread it further and because you are not using every inch of your space you can afford to remove the smaller light to reduce light intensity. Thats if the bleached tips bothers you.
Plant looks fine, its not perfect, but considering your situation and experience its not bad. Its hard for me to get a perspective on the size. But i wouldnt be worried.
A lower more even canopy just means more even bud size from top to bottom. Its not becuase i think you need to get more light lower, its that you need to make more room from the light to the buds and as you said you cant raise the light.
There is still plenty of room to spread that plant further and flatten her out going from the pic you posted yesterday.

Because they're wasting money. The amount they're spending on equipment is not going to pan out when they're growing very tiny amounts of weed that isn't worth shit.
They'd be much better off buying from someone.

Growing in small spaces is challenging and often done half assed, but even someone with a 2x2 can pull up to half a pound which surely pays for any level of equipment used to do so. Everything after is just gravy.
Besides that nothing beats growing your own and for some of us not having to wait down a dark alley to meet some reprobate who's going to sell you a wet bag of shite is a bonus.

2 x 2 with only 7 inches of space.
Yeah. Sure. Right.
You're completely full of shit.

Only partially.
But I concede not in a 2ft tall tent. I thought you were talking about micro growers as a whole and missed the 2ft height comment about that particular clone tent.
Would have to be 2x2x3 at least.
I know it to be true for a fact as I have friends who grow in 1mx1mx2m laid sideways.

Obviously, you didn't bother reading the OP when he stated he only had 7 inches of space between the light and tied down plant. That means he's growing under a fucking bed or in a fucking footlocker.
But you're giving him advice as if he were a pro grower in an 8 foot tall tent.
Shit man. Fucking READ.

I had bleaching similar to your pictures, one strain out of 5 under BlackDog 400 (true watts) "full spectrum" led lights. Lights were about 8" - 12" above buds. My guess, no science, is that spectrum mixing is the problem. Those led's have lots of little diodes of different colors spaced in some special proprietary arrangements. Split that light through a horizontal slit and each color seems to separate, perfect little lines of different colors, very pretty actually.
I use Timber cob leds now without any such issues.
Smaller grow containers could be turned and moved around, just a thought.

You should never grow in an area that you do not own or have gotten permission to grow in, if you are caught you could cause legal problems for the owner that did not know.
