Does this look like light burn? Please help.

Please let me know if this looks like light burn on a few of the top buds. I'm running three 600 watt hps lights with the closest buds being 20 inches away. I'm also running three 2000 watt LEDs that are a good 3 feet away.

The plants just started their 5th week (29 days since flip)

I'm growing three different strains and it seems like for the most part it's coming from just the middle strain (london cookies) if it is even light burn at all I'm not sure that's why I'm asking. Any input would be greatly appreciated, I've put a lot of work into them and I dont want anything messing them up, thx in advanced.20190203_120554.jpg 20190203_120545.jpg 20190203_120549.jpg 20190203_120749.jpg

Looks more of a cal mg issue, what’s your medium soil or coco and your ph?

Calmag issue? Then I would see issues with the leaves which I dont. I'm using fox farm ocean forest soil and purified water with my big berkey. I'm using lots of nutes and additives so I don't think its calmag. Does it look like light burn/ bleaching to you at all or does it look normal? The top buds I'm talking about

Sorry, here are a few pics with lights off and the flash on. I dont have a close up of the ones with potential light burn but here's a few pics with some of the buds in question. I would take more pics right now but they're in their dark period right now so I cant disturb them.20190203_183725.jpg 20190203_183719.jpg 20190203_183651.jpg

Guess the hps gave it that fading look. Leaves don’t look like they are cupping.

Is the the hps double ended?

I know the hps lights are on but if you look at the first 3 pics with the hps lights on you will see a close up of the buds in question. The tops are very light and almost white calyxes it seems like. Maybe I'm just being paranoid but they are definitely lighter on top than some of the other strains.

No they are not, just three 600 watt hps bulbs and three 2000 watt LEDs.

Just some light info, my lumens range from 100,000 to 170,000 on the canopy. My lights are between 20 inches to 27 inches from the top of the buds for the hps lights and the LEDs are a good 3 feet away.

The LEDs are king plus 2000 watt double chips 10 watt diodes and I'm running 3 of them.

The area I'm growing is about a 9 by 6 foot area. The room itself is a 9x12 foot room.

4840÷54= 90w/ft, I've had bleaching with an hps alone on some strains at 75+w/ft.

If it we're me, id think im hitting them too hard and might just pull a 600

Ya I'm thinking of axing the LEDs and just run the three 600 watt hps lights so I have 1800 watts total. My fear is lower potency due to too much light. I would think that 1800 watts for a 9x6 area would be fine since the average bud is 24 inches away and the closest is 20 inches. This is my second grow so I have a little experience but I really thought they could handle this much light. Good thing I didnt run the 1000 watt bulbs lol.

In your opinion does that look like light bleaching to you on those first 3 pics?

The first three pics is hard to tell under an hps, the second set of pics look like some colas have a bit of bleaching up top, towards the center.

Ok, thanks for the input. I dont know much about bleaching but will that repair itself if I lower the light output since they're only in their 5th week?
