Hi there, Does anyone have a solution for these lightleaks caused by kingbrite QB’s? I’ve tried different timers but the problems persists. thank you

Hi plant wizards, I feel like the growth of my cannalope haze has stunned.the new leaves are twisted and long and thin on top of the flowers. I’d think that the leaves should be datker green with too much N? I’m running GHE nutes on a dwc set-up. There have been some hot days here. Ph has been...

Always halfway during flower.. and sometimes in veg. Last weeks where ussually rather uneventfull. I used h2o2 to stabalize the ph.

It must’ve happened when I readjusted the airfilter ffs. If I had to guess that was two weeks ago. Also mucked around with it on sunday but thats early to have caused this I assume. Thanks a lot for helping me out!

thanks, thats very usefull advice.

Mann i checked my timer and I accidently pushed in one of the dails making it light for like 30 min I think two hours before the lights where suppose to go on. Amazing catch! Thanks.

Yeah I caught it early, mandarin cookies photoperiods. The buds under its are still swelling, so I doubt reveg. Just some of the smallest higher leaves on the buds turning yellow the others are curling and changing shapes. I’ll check the timer to be sure its on 12/12

They where at 30/40 cms

I’ve had this happen with me a lot with GH. Problem was gone when I switched nutes and gave my tank a good rinse

Hi guys, I was wonderingif you could help me out, I may have zapped my plants with a little too much light. I already dimmed the lights more, checking if I did the right thing. Week 5 of flowering on DWC aptus nutes in a 3x3. 2x 200 watt dimmed qb’s.

Thanks, I run several small tents so its not ideal. And I cant make one big light like you suggested. Love the idea though. I already have the drivers, for me its not worth to invest in new ones. Thanks for clarifying so I can be on my way.

Thanks, you confirmed what I was afraid for.

Can I combine two different Kingbrite QB’s? I’m working on two 240w boards and for the plants it would be best if i could combine one of each (one board with 660nm, the other with UV, 660 and IR, both by kingbrite) new QB on the heatsink. The drivers are the hlg-240h-48ab. The boards are...

So I had one last question, I’m now working on the two 240w boards and for the plants it would be best if i could combine one of each (one board with 660nm, the other with UV, 660 and IR, both by kingbrite) new QB on the heatsink. The driver is the hlg-240h-48ab. The qb’s are both stated to run...

So thus topic might be a bit old, but I can confirm that crappy nutes. I also ise General hydrophonics. Causes these problems. I never had these problems with other nutes. (Canna irionically because not the best either and aptus, so far I love aptus.)

For now.. this will do.. I’ll be looking into better stuff once I get back on my feet financially. Like a said, these havent broken down for me yet so.. fingers crossed. Thanks for your help once again

Aight, so to cap it off. I got replacement boards from KB. They gave me a whopping 5% discount, but since these are dogshitcheap I couldnt be bothered trying to get the price down. I did however get the ones with the epistars 660nm. Because the boards I have running here that aren’t broken are...

Thanks for tips guys, I’m going to look into getting new boards for sure. Gonna see what my options are and what matches my budget and go from there.

Dammit.. ordered those 2 weeks later

So after some email issues I finally got a hold of KB. Their warranty is only a year for the QB’s since I discovered this 13 months after the order the warranty is void. I’ll quickly have to check when I bkught the other two that show the same problems.
