Root Rot? or Nutrient Deficiency

Just run her on tap water that you bubble for a couple hours first to get the chlorine out until you get some cal/mag. Not sure the cal/mag is as big an issue as your over feeding. It really throws a lot of stuff off. Take note of your new growth in picture 4, see that big hook on the end? That's another easily recognizable symptom of over feeding. She'll come around great and be a beast!

this is perfect for scaring a cfl grower out of the hydro world an back into the cloest growing lol

BUT it wont scare me away! i cherish challenges like this when growing!

Hope you get your issues sorted quickly usairdog

ok so today i am changing her res water, 3 gallons, i'm gonna follow your advice and cut back on the nutes, ill drop them by half and work up from there, i'll add aquashield and make sure res is clean, (did you say bubble the water, like in a separate bucket before adding it to the res?) not sure i can do that i dont have another bucket, but i will use ph'd tap, will the chlorine kill her or damage her more if i dont bubble the water? man i'm so glad i found this forum you guys are the best.

Dont cut back your leaves. Train your plant with the help of a screen or a net. The only thing this guys right about is saying that top fuels right, cause he is.

What pic did you look at? That is about as pure Indica as you can get, yeah it's a cross but with another Indica. As with LA Confidential and other pure Indica's of the same plant structure. You DO need to prune back the large heavy stem leaves and some of the others surrounding the buds at around 5-6 weeks into flower so the light gets to the buds to aid in their bulking and ripening in an EVEN manor!
Further more, That "baby" plant is at least a month old. That's 4 weeks in case you have trouble with math. At that point he should begin full strength (or close to it at least) nutes as the type of plant he's running not only can take it, It will help it's veg growth to speed up a tad. Not to mention he is NOT burning them! (He maybe is close but I sure DON'T see any sign's of it being bad enough to have to reverse it. I mean do you see any loss of color or necropsy in his leaves?) It has a CalMag def.!!
If 70F is not the mean of the plants temp range what is? The higher the temp, especially in flower slows the plants growth. Temps over 85F approach the point where the plant will almost go dormant! Also, high temps in flower promote HERMING! and slow ripening down! Cooler temps at the late stages of flower PROMOTE a timely quality finish! So attempting to hold 70F with a drop in temp at night of up to 10 Deg. IS the best "target" area for ambient temp.!

The 30% add back system is an old rule of thumb I like to give out to "newbies" to get them going in an easy way to understand and learn from....Your res. PPM's are going to rise naturally and adding back at full strength will begin to burn them with overfeeding. While adding back plain water will work. a lot of people here want to try and "push" their plant as much as they can and ask how to ALL the time. This IS a safer way to apply a "full" power feeding tactic that's easy to do, all the while keeping in place the complete "dump and replace" that should occur with all hydro applications, at least every other week. This method helps to get that done in a timely manor!

I'll bet I'm old enough to be your grandfather and I've been doing this for over 30 years. Now I'm NOT saying I'm the best, and I'll be learning more about everything in life till I die. But I try and help those who ask with advise from experience. Maybe it's not how some others may do it. But it DOES work, and promotes learning at the same time.
I don't mind if you disagree with what I suggest.
But if you want to troll someone, I suggest you find some one else to pick on. Because what you've said here shows you're level of expertise IS lacking.

Are the TIPS of your leaves burnt and brown? No! Then you're NOT overfeeding them! DON'T reduce the nutes at this point....
When the tips of your leaves are brown and dry. Then your on the "edge" of "to much".
A good deal of growers LIKE to run their plants with that showing. Then they know their giving it all they can, to do it's best (I personally don't subscribe to that train of thought. I like to be a bit back from that edge).

You're plants FINE. Give it some Cal/Mag (like maybe 2.5ml a gallon and go up to 5 if need be slowly) and be happy as you're DOING A GREAT JOB SO FAR!

BTW, You won't need a lot of Cal/Mag as the new growth doesn't show the "splotchy" spots on them. It's just a safe move and will help down the road.

For your space and how you want to get her to be around her size potential....Keep running in veg till she's like 20 inch's (with that strain you'll get around 10-15 more inch's in flower) and then switch to 12/12.
Read Uncle Ben's topping thread and top her to get a better yield for her size. Looks to be about the size to top her now.

and yes chlorine is toxic. let your water sit out for 12-24 hours before you use it. dwc is what ive done for years. cal mag may help but id bet the water situation is more likely to cause the problem, also temps can effect nutrient uptake. so your res has to be kept at a certain temp range or it wont take some nutrients effectively causing damage

I remember years ago having to let water sit out for a time to get rid of chlorine,then 1 of the master growers
said it was not necessary.I was so glad to find that to be true,I haven't let water sit out for over 3 years now.
No problem. GL,GG,&HY!

Like others have said.. Too strong of nutes and poor root development

It takes energy to absorb nutrients into the roots. The higher the concentration difference between your roots and nutes, the more work it is. If you were running a marathon would you want a glass of water or a milkshake?

1. Clean Rez.
2. Mix fresh nutes using a flower formula NOT veg (you don't need nitrogen right now you need root development nutes
3. Ppm = 500 TOPS!
4. PH to 5.5 and let it rise on it's own

If you really want healthy DWC plants then get rid of the h2o2 and other sanitizer and start making beneficial tea. Little more work, but MUCH healthier roots and plants.

yeah if you don't feel like cutting corners listen to legally flying

^ what he said. But then again, what do I know about DWC...

14 plants, week 4

and the other option is rdwc, that has so much dissolved oxygen that pyrethium(anaerobic) is very hard to get

I have only popped 4 P Chunks, but both times I've dropped a cpl beans they have been the most finicky little fuggers in the tent.

Its not Pyth that you have to worry about its cyanobacteria!!! It doesnt care about o2 levels or temperature. the dreaded "slime".

Lol "Milk was a bad choice"

true

Update:

- Changed res water, ph'd to 5.6 after settling til this morning. (was 6.9)
- Water temp 72F
- Temp in tent - 77 - 82 ( like i said it's near impossible for me to get the temp and humidity to line up perfectly w/o a controller, and im using a humidifier on a timer in grow room - (outside of tent))
- Humidity - anywhere between 31% to 45% - (weather here sux and changes every 5 minutes.)
- P.h. - 5.6
- T.D.S. - 588ppm

Running her under 125w CFL, and 135w LED
Oscillating fan in tent
6in inline fan for intake
6in exhaust fan (outside sucking air from inside)

here is what she looked like this morning:

Suggestions welcomed this is how i learn so thanks again for all the input, your points are all valid and appreciated.

and here is her height,

update:


ok, i lowered nutes too far she went into shock i think, so i upped nutes, seems she likes it over 800. Used cal-mag - 3 tsp. 3 gal - 1 tsp per gal. I am running a small ultra-sonic humidifier in tent with air flow from intake duct blowing some air up and around and through plant. I have a oscillating fan inside tent blowing from top of tent across plant. I have no idea what im doing wrong, is she just stretching and making the calcium deficiency spots on her from before bigger? or is she still not getting enough cal-mag. I have used cal-mag for 5 days. or is that some kind of mold?

Sigh. I love it when you give someone solid advice and two or three days later they just ignore it.

Too hot and dry for that strong of nutrient. What is this "went into shock" shit?

And did you switch to a flower nutrient?...I'm guessing not.

Too little roots for too much foliage. But yeah, keep dumping more nitrogen on her and running really strong nutrients...that will fix everything (rolls eyes)

ok, i dropped the nutes to 600ppm, after a day she looked saggy and turning greenish brow
i cannot repeat, cannot adjust the temp or humidity w/o a controller - this is done by me personally every hour, i open windows, the humidity goes down, i close them the heat goes up, at night i cannot be there every hour on the hour, this is the best range i can get her.
i am running her on cal-mag, aquashield, flora micro, floragro, flora bloom, all half the nutes i was before, the lights are almost 2 feet from the top of the plant, i do have a co2 natural compost hanging above her in the tent. i have an intake fan blowing bottom to top, oscillating fan blowing caddy corner top down. i added clean filtered phd water to 6.2 (per cal-mag instructions) and the ppm is now 794 she looks healthier but the spots are still there.
