HELP Re-vegging 3 weeks into flower leaves turning yellow is this normal/

hey i am currently re-veggin 3 weeks into flower after learning sex and i know that you should expect the knew growth to be distorted but my leaves are turning yellow lke i have a nitrogen deficiency and my tips are burnt can this be due to the stress of re-vegging or is it more likley a deficancy.....to re veg i gave them a week of fresh water then started with a low dose of veg nutes

Its a difficult one to make a call on for you without seeing the actual plants themselves. Some photos might help.

...here is one pic more to come they are being low stress trained as well ..

i recommend removing bud sites, but i dont guarantee that, cuz when i revegged from flowering the bud sites were pretty developed and the buds will die if you dont remove them.

the buds are basically no existent i just was checking the sex and about half the sites have already died off,...i am using botanicar pro gro and botanicar original berry sweetner at a little more then half strength to start to me it looks like a nitrogen difficency but i am really not sure will take more pics toomorrow to post but one plant looks liek its getting better and one looks like it is getting worse....

one of my ladies is now looking better but the other one is looking way worse on top of the yellowing leaves and burnt tips it is now really droopy and looks extremely sick...both plants are getting exact same amount of nutes so i really need help identifying the problem cause i dont know what is goin on

Reservoir temperature? The drooping is worrisome and could be root molding.

The burnt leaf tips appear to be temporary, caused by a spike in N consumption/depletion and the stress of going into flower, possibly compounded by the revegging.

Anyway, I think you're past that particular crisis.

the thing that is bothering me the most is one plant is getting better and the other seems really sick when i woke up this morning it was drooping bad i cleaned out the resivor immediately....here are pictures from today of the dropping plants plus its root system and then a picture of the plant that seems to be getting healthier

also i dont know if this matters at all but i am using aquarium ph up and down which i have used many times before with no problem i just really need to figure out whats up cause she is defiantly dying

Are there any dark patches in the roots of the sick plant? If so you will need to treat your nutrient tank with some form of water conditioner that contains hydrogen peroxide. If that is the case ask your local grow store for a treatment for Pythium. Also what is the pH and ppm you are currently feeding them.

The other thing that comes to mind about this particular case, and many other grows that Ive seen on this and other discussion forums, but when it comes to sexing seedlings the tendency is to either take a clone and switch, which is the common method, or this one which is to switch the seedling then switch back.

There is a third method....

Seedlings will show their sex eventually no matter if you switch them or not. One of the reasons for taking a clone and switching is that people believe that it guarantees the plants sex, and it does in that sense, but in the end plants will tell you their sex even if you do not switch them.

Grow videos tend to recommend growers veg seedlings for 4-6 weeks then take a rooted clone (add a week or two to root) and switch it, then within 2 weeks you should see whether the clone is male or female. But what I have never seen on any of those videos are what happens if you just let a seedling veg away for the same amount of time. Lets say the usual 6 weeks of veg, plus the 2 weeks to root the clone, then 2 weeks to switch the clone to find its sex is 10 weeks in total.

If you just let the seedings veg away for 10 weeks or so they will show female parts if they are female without having to switch or reveg anything. The difference between the various methods not being time saving then but being less stress. Taking a clone/clones from a 6 week old seedling (as seen on the greenmans grow vid and others) is stressful for the seedling. Turning a seedling to bud then switching back (revegging) is even more stressful for a seedling, and in total amount of time taken, is longer than just vegging a seedling till it shows sex (6weeks veg plus 2 weeks switch plus 5 weeks revegging).

there are a few dark patches on the roots..so you suggest running strait water with some type of water conditioner? the plant looks even worse this morning she is even droopier if i dont figure it out fast definitely goin to loose her....Also ph is inbetween 6-6.5

unfortunately my local grow store is closed on the weekends due to the struggling economy i have heard of being able to use hydrogen peroxide to cure root rot so if anyone knows the steps for just using straight hydrogen peroxide it would be greatly appreciated

I personally don't think its a good idea in hydro to every run just straight water as a means of fixing an issue. You can do that in soil because soil retains a lot of nutrient even if you have flushed. In hydro healthy roots are everything. Pathogens in the water can hurt plants severely and can attack roots and kill the roots. Pythium is the main culprit, that micro organism will attack roots and the visual sign is darkened roots, dark brown roots, slimy roots and eventually smelly roots. Pop down to your local hydro store and ask them for a treatment for pythium. I can give you list of products but since I do not live in your country, your grow store probably does not stock them.

Since you are in veg the pH should be between 5-5 and 6.0, and you want to be running a ppm of about 400 while they are healing.

alright man thank you very much
