What is optimal distance for dual 315w cmh bulb style fixture from plant canopy. Running nanolux 630w dual single ended bulbs. Looked online for it and cant find anything including a ppfd chart

I would say theres a very low likelihood this is from a "lack" of light considering the wattage you are pushing out 16" away from the canopy. There are people who grow killer weed with 100w cfl's (albeit a small yeild). Mars advertises a ppfd ranging from high 900s to mid 700s in a 4x2'...

Tbh it kinda just looks like soil or peat particulates, could be working it's way back through your pump with a bit of back pressure. I think if it was like an algae like substance it would float to the top

Ok so looks like you have some foxtailing and some white pistils which I have had as a response to heat stress, now of course this istrain dependent as well. The fact that it is lacking colour and has the foxtailing and pistils makes me wonder if it has ever gotten very hot in your room or if...

Are you growing hydro or in a medium? Sometimes I get medium in my res and it floats around and is a landing pad for stuff to replicate on. I've never worried about it

Almost never will a lack of nutrients cause a burn look in concentration of the edges and or tips, this looks to me like overwatering and inability for the roots to transpire water through the roots and up and the stomata, this will highlight ph issues significantly as the low ph water is now...

I notice a distinct increase in cardiovascular endurance with indicas, call me crazy but cannabis is an extreme performance enhancer. Both physical and mental. If I burn before a run I actually look forward to it rather than having to force myself straight

One Not trying to split hairs with you( pardon the pun) but I never directly said white widow came from the hairs, just that the strain is very white and in my experience with it I have had a higher ratio of white pistils then other strain. That being said, I never really knew the definitive...

I think there may be some stunting due to heat stress, depending on how significant it was. I have had this exact look and situation from hps heat and light stress. For me the white hairs didnt seem to mature and I said f*ck it after looking at the exact same thing for 2 weeks and hacked er...

I've seen this so many times before on indica plants, I lean towards genetics, regardless it has yet to have a negative impact on yeild or quality for me or anyone else I know who's encountered it

Also bear in mind the name of the strain, white widow is called that for a reason. It often will have white hairs all the way till the end of its light cycle in my experience with it

Did the plant have any heat or light stress throughout its life cycle? Do you have an idea of ambient temp around main coal/top of canopy. What light are you using and how close is it ? Hps has given me issues with finishing before and it looked similar to this

Bugs are gone from what I can tell

So true, I just ordered some seeds from canuk seeds a week ago. I'm so tired of getting the run around with clone guys, their quality control and TLC is never that strong because they only have these things for 2 weeks max, for us its 3 months!

Morning everyone, just wanted to provide a quick update. I came downstairs this morning to see the little ones and although some have some foliage burn almost all of them are looking up and have a healthy "stance". I think I may be out of the woods this time. My only conclusion that i can think...

This is the problem though its killing the second batch, which were not directly sprayed. I'm at a loss, I couldn't imagine a small amount in the soil killing the second ones. So weird

Thanks bro, you think it's so strong that it would stay within the soil after a strong flush (I had like 50% runoff).

As I said it did not measure but I imagine far too strong.

It will I just have to go do a sage burn in there to ward off bad spirits lol

I can unscrew one of the bulbs but I have vegged under 1000w de Hps before with zero issues, and no word of a lie the ones right under my cmh look ok so far, If i walk down there in 2 hours and more are wilted and dead I'm tearing them all out tossing the dirt and then venting out the air for 2...
