Iceni

I just use the tent buddy app it has a nice DLI meter, it's worth a look, it also has a vpd calculator too

Got the light today looking great, good coverage . I'll be testing the output later on and dial in the DLI

I have been debating over LEDs and specs, it's all to much to choose from, so I just bit the bullet and got a light that is 640w 8 bars Samsung's 301B, 301H , Osram , all the usual, it's was listed at £500 knocked it down to £450, it's a Chinese made but I don't care if it covers a 6 X 6 veg and 5x5 flower I will see if I can get the specs to see if it helps you, I will be testing it in the next few days, 

One of my dogs a black lab is called lolly too 😁

I would like to see nirvana offer regular seeds of this strain. My first pack of seeds ever was reg bubblelicious, I would love to breed it into something modern 👊

The problem with k deficiency is that it does look like burn at first, I knew it was not burn as I was underfeeding from the start and that's just how I roll, unless you have access to soil testing 😂 you are at mercy of the tools you have and the signals from the plants, I was pretty sure it was deficient just had to wait until the tell tail side yellow on old growth, I bet a lot of people have had this at some point and made things worse by flushing and the like, it's all about patients and the plant will eventually show you a definite signal, hope it's helpful for anyone, I'm not stressed because I know from experience, I just get confused over the symbols p & k , that's smoking and age lol
