You are probably right about that.:thumbsup:

I'm just a simple grower, but that looks like too much sodium, and powdery mildew, from the HPS lit photos.

Natural light snapshot might get ya a firmer opinion.

You really go 8 hours with out feeding them? Also make sure you Ph is really at 5.6, because ph pens need to be calibrated quite often, and if ur any lower then ur going to get lock outs, happened to me, and u get dark rusty spotting like i see here. plants like low ph for calicium, and high ph for magnesium, u fall to low and ur certain to get an MG lock out from the calcium. If u havnt changed nute concentrations then its not an under or over feed. If do like ur supposed to and add a little more each week, then no way ur going to get burns like that, that quickly. Routine res changes? unused nutes build up.

Besides the powdery stuff they look normal for 6 weeks. Those large leaves should be turning yellow and dying off. Yes a pic with no light on might help more. This pic is right at 6 weeks of flower and the yellow leaves started turning just like yours. I can get more pic's if you want to see more color change.

i love it when LOC gives us little glimpse of his garden! Like he is purposely teases us with little snipetts!

lol no doubt :D

Hey Marty and Tiny, I just got my camera back after 6 months in the shop. I think they lost it and gave me a new one. LOL.
I will get some awsome trichomes shot to post soon. Forgot what they looked like almost. It's better than the little magnifier I was trying to use.

everyones been teasing me with pic's now it my turn. LOL.
I hope we are all set for a nice green Xmas. I got a bday and harvest coming up in 2 weeks, Just in time for the holidays. Papaya is the bud in the pic with Hawiian and some skunk that I am thinking I got mixed up with norhternlights. They don't smell like skunk. LOL. Oh and one S.A.G.E. Small batch of northernlights and skunk for new years.

I'm getting alittle old but I wish we could all sit down and have a good old smoke out like me and my long gone friends used to have. If they could see the stuff we have now.

Oops hijacking not allowed, SORRY. LTMS.

I am officially a hijacker...and I apologize.:jointsmile:

If you guys are ever in the Bay Area, hit me up on here, and we can have the Great American Smoke out!:stoned: I too miss the days of hanging out till 3am stuck on the same spot of my couch! Not being able to comprehend anything I am watching on TV.

My christmas is not going to be Green this year...but I will be rocking out the new Year with some nice Blue Dream and Space Queen...I will for sure ring in the near year with a bong rip for the homies on this site!

Can't wait to see more pics LOC!:jointsmile:

In dirt or even in rockwool yes, but definitely no for coco based growing.
