Please advise, been flowering for 2-3 weeks now and some sort of deficiency!!!

So this is my 3rd attempt at using this AG, and my first female... unfortunately i had to go on a vacation for week and left my roomates to keep an eye on here. i came home to this... yellowing and dieing leaves with some browning tips, white hairs and flower spots look ok, after all the research ive done here i believe its N deficient, someone please help me confirm!
this was right when i got home from vaca earlier this week... these next pics are moments old


Also ive still got some old roots in the reservoir from another plant that i had chopped down, i was unable to get old roots out due to the fem's roots here have wrapped themselves around the bubblerock i have in bottom of AG, so i guess my next Q would be, if i carefully cut some of the roots away from where theyre tangled do u think shed be ok?

i just want to get old guy outa there so she has the entire res to herself... ive got superthrive that i havnt been using during flower and i was planning on trying to get my hands on some Nitrogen nutes, but hopefully somones got some advice. thank you for everyone's time in reading this, and all advice or questions, please post.

Parklax:
One thing I was taught was if you're growing with hydroponics you can't take time off. That's how fast things can change and you can lose a crop. The last time I took off for a long weekend I came home to two out of five plants dead, one sickly, and the nutes in the reservoir were totally out of control. My friend was even worse off. He did the same thing and he returned to a dry reservoir, a burned up pump and all his plants were dead.

I've never trusted my garden to anyone else. Did they check the pH and water level everyday? Hopefully considering your friends were able to do more than just help you smoke it lets look at a few of the variables.

1. What are you feeding them?
2. What's the pH?
3. Are you sure your lights are still on a 12/12 schedule?
4. What do the roots look like? I like clean white roots. If they're tan to brown you might want to try a root tonic on your next weekly nutes change.
5. Is your reservoir clean? Algae can mess up your reservoir, hence your plants.

You might want to flush them and re-feed if you haven't already. From the size of the pictures I can't see much more than dead leaves and white pistils so I'd say that they're not ready to harvest yet but they do look more stressed than usual. Please let us know what you do and what the outcome is.

hey man, thanks for popping in;
i mos def did "train" my roomie in checking PH and went over with him several times what he needed to do for me so thats outa the way lol, was only gone a few days. as far as the other variables here:
1. shes getting strictly water that is at the correct pH level every res change, and thats about once a week, of course topping her off in between changes. during veg i used this superthrive i got sparingly, was afraid to burn. currently i did order some maxibloom to help out, should be here in a few days
2.i check pH like a fiend, twice daily most of the time. its always around 6, never higher than that, but normally lower
3.lights are a buncha CFL's and certainly on a timer set at 12/12
4/5 as far as the res is concerned, i do change the water in it, but due to the roots being tangled around the bubblerock in the bottom of my AG so i am unable to take the top off completely and get in there. i did just cut out an old stump of a male i had in with her and the roots are all still down in the res all brown and shit, i try and pull them out as best i can, but im afraid to damage the good roots, lol idk...
so my next Q i guess would be how ruff can i be on her, as far as "trimming" roots, i am very reluctant to do this just caus ive never done anything like that before. after my post earlier i did go ahead and clip all that dead yellow fan leaves and shit, here are a few better pics hopefully.

Also i was following jazzy's journals here on the board and in his first i saw he transplanted one of those ladies out of his AG, and in order to do that id imagine he must have trimmed roots to get it out of that little hole. also in his current journal he did mention trimming his roots so they dont become bound (i guess like mine lol) so im assuming this is necessary ive just never known that i need to trim roots. so i guess what ill do is gently pull up on the lid and "separate" the roots from the bubblerock with carful trimming lol, wish me luck.
Oh and as far as algae, i almost forgot... i was worried about that as well so last night i scooped up a thing of algae control made by tetra, says its good for fish and water plants, a broad spectrum algae control it says on it. anything anyone would suggest? or i hope this stuff will do the trick.

again i thank you sir, and thanks in advance to any others whom come on by.

and are you unable to click on those pics to make bigger? or im probly posting them wrong lol... GD computers

Hey Parklax, hope everything has gotten better.


You said you are not using superthrive while flowering, what did you feed them while vegging? Are you currently only feeding them PH balanced water?
What are the wattage of the CFLs you're using? Are you planning on using the AG Hood?

A very good friend of mine repeatably tried to grow 1 plant in his AG, in his closet (With slight ventilation) and a mirror (setup in the same manner as your's is). Aside from him not providing the correct amount of nutes, a good deal of potentially reflected light was absorbed into the mirror. I would suggest the following

1) Get some Panda film or White construction paper (Panda film is preferred in this case) and tack it to the wood in the back; having the panda film wrap around abit. This will increase the overall effectiveness of your CFL setup.
2) Not knowing how you are feeding your plant. I would personally suggest 1/2 tsp per gallon of distilled water. Completely dump your reservoir.(Don't worry about those old roots.. They will not interfere in the existing plants growth.)
Once dumped, clean out any visible buildup within the reservoir. (Do not worry if you are unable to remove the root base from the res; leave it in there and don't traumatize it)
Pour as much of the pre mixed (1/2 Tsp (of bloom Nutes) per gallon of distilled water (At your local grocery store) into the reservoir. Top off the res every day until the 1 gallon container is 100% done.
Repeat process @ 2/3 per gallon of Distilled water.... (Do this until you are at 1 tsp of your own Ph'd water *i.e. Once this 3/4 strength gallon is done*).

It's understood that you have the means to identify and correct potentially "incorrect" Ph values. However, to ensure you are able to successfully come out of this; removing the need for your interaction with the plant more so then what it's been experiencing is best.

return the "tetra" algae product.
Leave the plant alone and allow "It" to grow.

So this morning here i do believe i saved a life.. well with the help of HSA of course! but i do believe shes well on her road to recovery already. i was able to get the lid off of my AG and i think i may have removed a few of her roots, but mostly just released her from being wrapped up with other dead plant matter and being wrapped around the bubblerocks ive got goin down there...
gave her roots a good massage in a big bucket of water and some other goodness, to rinse off all the algae and shit... i wish i wouldve taken a pic of that nasty dirty water once she was done bathing lol. it was sick.
i then scrubbed out the AG res real good, more or less rinsing it thoroughly over and over again until it got like new. after that i cleaned up the air lines goin into the res for bubbles, which i did notice a disturbing amount of goop on.. aka algae like black shit... i chalked it up to having clear air lines and not dark ones leading to the alg, so i was sure to wrap them up so no light gets in there when i put her back in, roots are swimmin around freely in the jacuzzi now and nice and white as compared to what they were.. please if anyone's got more ideas on what they thinks goin on here, please chyme in also commments or anything u notice please ask or tell me bout it, i love all the knowledge and great people this place has got. thank you again for saving a life!

i was planning on progressively getting stronger a gallon at a time like u had mentiond, but do u think the superthrive will be sufficient? i remember somewhere it not being the best bloom nute, so im just gonna be usin it here until my maxibloom gets to me thru the mail in a few days. so should i wait and just flush her with water until i get my bloom nutes or just keep rollin with small amounts of sthrive progressivly getin a bit stronger until i get my bloomers then give em both? or replace one with the other... one other thing i almost missed was ur comment about the mirrors, i didnt even think about that! i certainly appreciate the tip, i just assumed it would reflect just as good as anything? lol i guessed wrong. thank u again though! and ill keep this baby updated and let yall know what happens... again thank you so much, this is my 3rd serious attempt at this here and my first female..

oH and as far as me just growin 1 lonely little plant lol, yea i know, i did germ 4 seeds i had, 1 didnt split, the other 3 i planted here, and this is the only gal left. other 1 was dude and i think 3rd didnt make it or something i dont remember? but yea it is in a small hutch thing i have here but ther doors are always open and she gets a nice breeze all day while the lights are on

shit and forgot.... the CFL's im using are 2 big ole 46W and 8 smaller 23W i believe all 2500K or 2600K

Superthrive is not a nute. Read the label. Add it to fertilizer, not instead of. ST is vitamins and hormones. While benficial to your plants, it is not nutritious. You need food. No wonder your leaves are turning white, there is ZERO NPK in your res.

lol ok thanks i guess... my bad, idk i got those stupid AG nute tabs but im not using them here, and i guess im an idiot, but bloom nutes are in the mail here so maybe shell hold out... i also am going to scoop up technafloras recipe for success, got little bit of everything for me, and ive heard some good things about it... again thank you for enlightening me that sthrive is vitamins and hormones, not nutrients i guess. and i certainly did read the label, but u know ive just got a small bottle here and theres a lot of fuckin writing of all kinds wrapped around it, so thanks for clarifying... and hey man lighten up its saturday.

i reckon ill toss a chunk of this large AG tab to disolve and put it in my refill gallon and progress with these until bloom nutes get to me in mail. surprising shes done this well since i have ZERO npk in my res

Use one of the starter tabs, not one of the large ones.

Serapis you beat me to this fact, yes ST is merely vitamins that f**king stink!!! lol. Parklax I see you are here in the UK, that bloomer should be with you well before the plant is on it's last legs, you will be fine. I suggest though your research is more thorough in future if you want better results. I aint gonna lecture you but letting a resevoir get mank with old roots etc. is a total NO NO!!!!!

Students..........pah!!!

LOL.

Old roots never caused me any problems. (As long as they were not taking up the majority of the Res) Cutting through a mass of roots, not knowing what you are cutting sounds much more like a no no to me.

nitrogen deficiency

parklax man go to wall mart and get a thermal blanket for 2.88 a box its a pretty good amount of it better than a mirror and cheaper than panda plastic
