Hey guys, I'm new here. Well at least as an actual member, I've been visiting these forums for years. I have been looking into growing for over 8 years but I had to wait until I had turned 21 here in Colorado to legally grow. My 21st birthday was back in October and now I'm here 2 months later and 2 months into my first Grow. First off I would like to thank you in advance for any helpful insight into my grow, and I would like to welcome you to YodaBear's First Grow. I can not promise I will update weekly, but I plant on updating as much as possible. Okay, so I seem to be having issues with my main mother plant, she was given to me as a seed by a friend who had 2 kinds of seeds saved from a purchase from a couple of years before, she got mixed up at some point and so her identity was undeterminable between "Purple Stein" and "Low Ryder". I happily accepted his gift without much question but I have found it rather hard to find any information on a mysterious "Purple Stein" but after 2 months in and no obvious signs of any auto-flower tendencies I have decided she couldn't be the Low Ryder, so she must be the mysterious Purple Stein. From what I can tell she is a Sativa Dominant strain, but oddly enough a pretty short sativa strain. I have been having issues with her nutrient levels lately. I placed her in miracle grow seed starter (That was my first big noob mistake) since she first sprouted she has had very dark green, to dark green of leaves, right on the edge of Nitrogen toxicity. Because of that I went with bloom nutrients from Old Age, 5-10-5 ratio of NPK, staring at less than 1/4 strength at the 5th week in on my grow (I had assumed she was mature enough to handle light nutes) but after a week of using the old bloom she began to burn on the tips. I could not tell if it was from light burn, or from nute burn so the first thing I did was flush her. 6 gallons of 6.3 pH water through her 3 gallons of soil. This managed to stop the spread of the burn, but now 2 weeks later and after main veining her twice to get more main Colas, she is now yellowing at the tips as they curl backwards like they're drying out but they're anything but dry. From what I have read it seems to me to be a Potassium Deficiency. What do you guys think?
Also I forgot to mention that this main Purple Stein was troubled harshly as a seedling by thrips.
In summary:
Genetics: Mysterious Sativa seed known as "Purple Stein"
Medium: Soil
Water: Tap, pHed to 6.1-6.5
Nutrients: Old Age Bloom, CalMag, Fish Emulsion for Nitrogen, Vinegar as natural pH down,
Soil: Miracle grow seed starter mix at first, repotted into Black Gold soil mixed with mycorrhiza and big chunks of perlite.
Grown in 3 gallon round pots, I also have one plant in a fabric pot for experimentation.
Light source: Mars Hydro 1200 watt (570 actual watts) LED grow light customized to have extra 640-660nm LEDs for vegetative growth and one small Infrared bank for end of day IR exposure to induce dark time growth.
Light Cycle: 18-6, was originally 21-3 but I found plants to nodes to be to short and the plants to bushy.
Humidity: Kept at around 60% by evaporative cooling
Ventalation: 6 inch booster fan sucking air out through Carbon Filter.
Room: Grown in 6 tall 2'x4' space

One if you've been around for awhile even if only reading you should know, "TAKE PICS IN NATURAL LIGHT" folks can't help very well looking at purple plants. But thanks for the life story at least I guess

too much to read....what's your specific question?

My main question is, in your opinions, what type of nutrient deficiency is now being displayed by my Purple stein, I know I nutrient burned her and that effected all the old growth but on the new growth there is a different type of problem. I believe its from flushing the soil after the original nutrient burn. I will upload better pictures in a moment.

You're right, I did know better than to leaf you guys with bad pictures, so here you go. I just couldnt take pictures last night during their dark period which is when I finally decided to create this thread.
Here she is as of just a few moments ago.12-20-16.jpg12-20-16b.jpg
Heres the old growthOld growth.jpg
notice the burnt tips, definitely nutrient burn. I didn't realize how much nutrients are already in black gold.
Heres the new growthNew growth.jpg
What type of deficiency is that? Notice its not a burnt tip like the nutrient burn but rather a yellowing, my suspicion in Potassium Deficiency but I'm to scared to treat with anymore nutrients until I get more opinions.
 
Old age is pretty strong, 5-10-5 is really an odd ratio for cannabis in veg, even in flower. Too much P

Find a way to balance out the feed, which black gold are you using?
 
I would let it sit for awhile (no nutes / no flushing) and see how it recovers from the over-nute/flush crisis

I think it should bounce back assuming you don't over nute again

Black gold waterhold coco blend. I didn't think it would be high any nutrients since its a coco blend but boy was I wrong. The stuff is pretty potent and its my fault for under-estimating it. But the whole Heavy P ratio is what I was thinking. I trusted what my Hydro shop guy told me was going to be the best for organic nutrients (Or as close to organic as possible). Im thinking of supplementing some natural sources of K into the soil through a nutrient tea. What are your thoughts guys?

so you don't think the new growth is showing signs of a deficiency?
