First Grow, Advanced Nutrients, Penetrator 336x Pro LED, 600 HPS, Nitrogen Toxicity

Hello everyone! This is my first post of my first grow and I was looking to get some feedback on my progress and for some constructive criticism. I am at my 33rd day since the switch to 12/12, Using Advanced Nutrients Grand Master Line, Sensi A&B Bloom, mostly at half strength to a little over. I have signs of a nitrogen toxicity, and haven't flushed just yet, but have been feeding my girls plain R/O water with a small amount of Drip Clean since yesterday in attempt to work out some of the nitrogen from the medium. Growing in Just Right Xtra mixed with Just Right 420 formula, about 3/2 parts. The lights I am using are a Penetrator 336x Pro from Hydro Grow LED, which I might add is an excellent company to deal with despite the awful stigmatism they have acquired, they have been the most trustworthy and informational LED company I have come across, after an awfully painful experience with hydroponicshut.com and being blown off by magnum when asking specific questions about their technology. I am also using a 600w Hortilux HPS in the same room, a 5x5 Tent. 6 plants, THC Bomb, Moby Dick, Maui Wowie, DJS True Blueberry, Romulan Diesel, and Jah Kush. Again, this is my first grow and these were the clones I had available to me, though I would have preferred to work with only 1 or 2 strains. They also range in size from about 22 inches to 5'10"(The THC bomb exploded in flower and became a monster in my tent). Please comment on the Nitrogen Toxicity, and if some of the experts out there think I Should Flush, also please comment on if you feel my bud production is lacking where it should be. I am here to learn, so let me have it, Don't hold back and tell me how I'm doing!

just give them less N, simples...

I think that is an obvious solution, my question was more focused at does the nitrogen toxicity appear bad enough to where I should flush, or if it appears I can get by without stressing them out by putting 10g into my medium. If you read my post, I indicated that in the past day I have fed plain R/O water with a small amount of drip clean.

For me it is hard to judge the toxicity levels because of the LED,take some with the lights off. If the two leaves under regular light are pics of the toxicity I don't see them being overly green. A bit on the crispy side.I would just continue to leach from you r soil as you
have been doing vs. shocking them at this point with an all out flush.JMO

Yes, running the grand master line, excluding tarantula and piranha, as I did not have enough money for them starting out. Before giving them straight R/O water with the Drip Clean, I cut out the B-52 and Both parts Sensi (basically anything with N) to leech out some of the nitrogen, saw a bit of a turnaround, then went back to only using Sensi B at half strength and fan leaves began clawing slightly afterward, thus switching to plain R/O, until I see somewhat of an improvement. My Supplements are slightly over 1/2 strength, as I have worked up gradually as recommended by AN, but I have been careful to follow my instincts as well and go the "less is more" route to avoid burning. The crispy dry leaves are at the bottom of the plant, thought for a long time it was a Phosphorus deficiency, but with the combination of the dark green foliage and the ever famous "claw", I'm more inclined to believe slight nitrogen toxicity. I am aware as well that the lower leaves could be dying off due to lack of light penetration and this is normal. Being this is my first time doing everything start to finish on my own, I'm not real sure what type of growth rate I should be seeing. I have only helped in friends gardens with a few things here and there. How does everything look in your opinion for being my first? Do I seem to be on schedule or does it seem stunted? Again, you are seeing Day 33 since the switch to 12/12. Thanks for the replies everyone, if there's any more information that may help you help me, I will share as much as I can.

I will post pictures with the LED and HPS off tonight after 7pm so you can get a better idea of what shade of green they are. The pictures above were meant more for the purpose of showing the clawing

Look at all the great rookies that have exceeded many of the veterans in so many sports, professions, etc. Determination, persistence, and a hint of meticulous behavior is how I like to run my garden. I am simply trying to do the very best I possibly can, and produce the best quality medicine for myself and my fiancé, who has precancerous cells. Most of what we will produce will be turned into RSO, and that being said, quality is vital. I realize I am a "rookie", but if you're going to do something, why do it half assed? Yes this is a learning experience for me, and I am not necessarily "stuck" on, or an exclusive user of only Advanced Nutrients. I did my research, and found that growers are having exceedingly great results with these products, and again, I strive for the best of the best. You may say I am loving my girls too much, but when friends who work along side with the folks at Cali Connection are telling me I'm one of the few newly starting out growers that puts this much attention and care into my garden, especially my first time around, the unanimous judgment of "Impressive" and "Vigilant" is associated with my work, I feel proud to love those girls way too much. Your posts have been helpful, but to suggest I stop all additive feeding after my results have proven that per your own words "Buds Look Great", I will have to kindly disagree, even though I am a noob, and probably know nothing, right? I will post more definitive pictures of the clawing I am seeing and the foliage color without HPS or LED running so you can get a better idea of my slight worry of N toxicity. And you suggested I go back to using both sensi A&B, but wouldn't it be wise for me to begin cutting out Nitrogen in the next few days to a week close to nothing? This has been suggested to me by a friend who has worked along side Kyle Kushman, stating they cut out almost all nitrogen at about 4 weeks of flower. Let me know what your thoughts are on this, I will begin using Overdrive in the next few days and am tossed up between cutting out the Sensi A, but am worried about Cal/Mag deficiency. Thanks for all the helpful posts

man you are doing great! and i do not see any signs, As far as people telling you, that you are loving your babies to much, NOT possible unless you have pounding headache from the HPS light because you would have to be in there that long before i would say anything, that being said, They do need to just do there thing, I doubt you are rotating, but as im sure you know the most important time not to EVER mess with the plants for any reason is "loving" on them at night, during her 12 HRs or darkness, this is where more of the growing and THC growth comes in. I am sure this wasn't much help, But i wanted to say you are doing a killer job, Those 2 leaves you showed looks normal, NOT EVERY leaf is going to stay lush and prefect, if you had a nit problem, you would be more yellowing. Last thing, You say you have was it 7 strains? The pictures was that all of them? but just keep LOVING on them just as if they were your real babies and i believe you are going to be one proud grower when you harvest, Their is nothing like smoking your own dank!! Good Bye & Stay High!

Thank You PeaceGrow! I appreciate your feedback, it was helpful to hear I'm on the right track. I realize Nitrogen problems cause leaf yellowing when Nitrogen is deficient, but what I was concerned with was a minor toxicity, leaves looking a little dark green, minor curling of the tips of the fan leaves downward. Despite what others have said, I am still confident there is a tad bit of too much N. Pictures without LEDs and HID coming soon! I will be sure to get close ups of the dark color and clawing I am seeing. Appreciate all the help!

Here are the updated pictures, they were taken under a fluorescent. Notice the minor bending of the leaves downward, and the burnt ends that point upward. If this is N toxicity, I believe I've caught it before it has a chance to slow production. Another symptom of the leaf bending upward at the tip is a Magnesium Deficiency? Possible combination of Nitrogen Toxicity with a Magnesium Def? Let me know your thoughts! I will wait to make any adjustments until I'm confident of what this is exactly. Thanks everyone.

Anyone have any thoughts as to the potential Nitrogen toxicity? I fed the girls R/O'd water again tonight, they seem to be getting they're perk back a tad.

Well I am a new grower and really can't give you scientific garble like some of theses guys. But the fact remains I see healthy plants that aren't that dark,mine have been as dark or darker and they seem okay.
So if you are concerned and you see improvement from just RO waterings,I would say you are doing a fine job of listening to your plants. Mine just say Feed me Seymour..

Good looking girls Seymour, Appears to be Indica dominant from the leaf structure. What strain are you growing? how many do you have under your belt?
