Same deal as me mate, used 2x TSL2000, but within two months was having issues with multiple boards not starting up constantly. Was lucky enough to receive a beautiful SE3000 from @SpiderFarmerLED yesterday, and swapped it straight in. Got two weeks or so of flower left and hoping the extra UV can bulk out and add some frost during this last bit. Next grow will be 100% with the SE3000. Thanks Spider Farmer!

A trick I was told by a pro grower was you can boost under performing buds by turning your light back up to 18hrs/ day again for the last 7 -10 days. I tried it on my last grow and it did improve the size. I was told to watch for revegging if I did it for too long so 7 days at the end on 18hrs was how I finished them off.

This is madness. I have never heard of this before it sounds like a cool trick. The only concern I would have is potential re-veg but if you stopped it quick enough I guess it could be avoided. I actually do the exact opposite when I harvest. Sometimes on the last day or 2 before harvest I will unplug the light and go full lights out. total darkness before the chop.

He did say to lower the intensity ( forgot to mention that ) but with my 1000w hps without a dimmer the distance I keep my plants from my light I was good to go... I've only tried it once but I've had other top growers on here confirm it....Someone may pipe in on this.

so i think my ppm meter might be off its 1.5 years old and a cheap one off ebay if you look at this feeding and the last feeding the jumo in ppms is only from changing the batterys . i believe i can adjust with a screw driver but at the moment i have no ppm solution im really not sure if i should just adjust this one or buy a new one .
