I need a little help here please!

So I have a small problem as I am in 3-4th week of flower and the leaves comin out of the bud sites are clawing down. Obviously I have done some research and I just wanted to confirm that it's probably a nitrogen toxicity? I keep the ppms super low and they never show any deficiencies, but all of the sudden they started doin this crap. I am running basic stuff with tea and aqua flakes for base nutes. I decided to lower the overall base nutes and added some bloom boosters to make up for the lack of P-K. I dont need the "use EC" lecture, and just assume all temps and environment is perfect. It is definitely nutrient issue.


Here is the chart that shows PH and ppm levels for the last month.

They're not clawing, they're wilting. But its only one set of leaves, dont worry about it.

its not just the one set, its all of them. Wilting is what they would do if they needed water I think, and no they are good on water.

Any advice on my lil guys? Ebb n flow ppm1150 ph 5.6 temp71 RH52. everything else is going great! All clones from the Afghan kush are eagle claw. First week in 12/12 for all clones. Mom is in soil too. I flood 3x daily

Overwatered. let them dry out and keep em more dry than wet Think moist not wet. 3 times a day is way too much. I have 18 inchers in a tray with cubes like that and I flood once every couple days maybe once a day

They're wilted, man. Clawing is when just the tips turn down. It could be anything, maybe look at your "assumed temps". Arguing with someone whos trying to help you will definitely not fix anything.

I get the same kinda deal every now & then where bud leaves will lay down but i dont think its from excessive N , I stop all N after week 4 then for the last 3.5 weeks give em bloom nutes & all the micros & ive noticed it as late as week 6 , ive just came to the conclusion its normal growth .

My room temps are climate controled & canopy temps stay at 72 a half inch from the glass , my rez is geothermal so rez temps are allways at 60 degrees , your room & water temps are good too so im gonna say i dont see an issue .

If you had leaf curl , spotting or burned leaves that would indicate a problem but you dont .

From seeing your chart it sure looks like your on top of shit big time so maybe it isnt a problem & its natural growth , i use 4x8 flood tables & notice that kinda growth sometimes but its never on all the plants & theres no pattern when its gonna happen , i think your ok bro cause ive never noticed any difference in harvest weights & i ran 8 tables set 1 week apart so i'd notice differences in weight , some tables do that while others dont & after 5 yrs it still happens so i dont have a clue what causes it .

I'm with @panhead on this; I get it regularly but the end result is plenty- and dank.

If anything, I think you're running your nutrient strength a bit low, assuming you're using the EC x 500 = PPM scale. If you're using another one, then it's WAY low.

I've seen the claw, but until you see tip burn I think you're nowhere near a toxicity issue.

One more suggestion; find a way to stabilize your pH to within a few tenths of a point from day to day. Reading your chart tells me it's all over the place and ladies like consistency. This tells me that you may be seeing pH curl, just from bouncing around so much.

Hope that helps!

Thanks fellas, I saw it on the last grow a little bit but I chalked it up to a bad ph swing where it hit like 4.9 for a day. I hear us about the Ph though, I used to keep it super tight but then I was reading some research that botanicare did about DWC and how the plants will actually change the ph to find nutes and it could swing as much as a whole point(5.3-6.3) without any problems and it works! It does all that up and down stuff on its own and I just let it roll until it hits a danger zone. Maybe I'll tighten it up a bit and see if it helps.
I also thinks it's nitrogen too though because you may not be able to see it but the fan leaves are dark as hell. I'll keep you posted after a week and see how they look. Crazy room huh?! Out of control, I will flower earlier with the strain on the right next time.

You're welcome.

See now i let my ph move around if it wants to where i'll let it go up as high as 7 & as low as 4.5 for a day or so without adjusting ph at all , usually within 2 or 3 days the plants will of ate what they needed at the lower/higher ph & the ph will return to normal by itself , as long as your nutes are mixed right & you start off with a good ph but it keeps wanting to go up or down its usually from the plants needing better access at a particular nute , again if the fresh rez has a proper nute balance to start .

If your feeling as if the leaves are an indication of a problem & will effect quality or weights then what Ttystikk suggested with a more stable ph is really about all you can do .

Yea man I think it is an N problem. It has all the signs, and now that I think about it I may have biffed with my other room too. I was using floralicious at almost full strength for a couple weeks and I forgot how much N is in there. Like you said i am on top of my shit so I will surely have the data for you guys within a couple weeks.

Also, I was thinking about what you said about keeping the micros and ditching the N at week 4, but all my micros have a shit ton of N in there. Perhaps when this has happened to you it's is still the result of too much N, and we need to figure out how to get the micros in there without the N?!? Hahaha... I love growin.

Thanks bro. That was the problem. CHECK them out now thanks to you.

I can never stabilize my PH. Set itat 5.8 24hr later its 6.0-6.5 depending on the plant. Bigger feeders have a higher increase.

I try upping my feed cause I hear if ph rises and nute strength drops to increase feed. Then I get nutrient increase and ph increase still. Its like my plants are never happy. Sick of playing the PH game.

Wow. Dude i never had ph. Issue's but it sounds crazy! Stick with it
