Oh yeah, this has been affecting primarily newer growth shoots, but not all new growth(if that makes sense). The main cola is still nice and lush, but when I tied her down most of the side branches that came out started showing the signs. Not all of them, but 80 percent of them.

Yeah: Your problem's somewhere else. I doubt it's a mag def. In all likelihood there'll be something else causing that. If it was mag def it wouldn't show in your top leaves first.

What are you night temps like?
What have they been fed recently?

Whats yer ph on yer runoff bro? In coco you gotta have that ph right bro. I bet its too high right now man.

[Elements001]

been feeding with each feed, but the last two times I didnt water to run off. Before that I was watering at about 6.5 and the run off was about 6.0. This time I gave her 6.0 ph Water, and by the second gallon started to run off the pH was looking more like 5.5, so hopefully that'll help.
You know what,I think Im done with this guessing game of Ph test shaker thing. It works ok, but I need a definite number to work with. I'm just gonna srping for the nice meter they have at my hydro shop, (blue lab I think is the manufacturer).
I'm know my pH has been from anywhere to watering at 6.5 with run off 6.5, to watering at closer to 5.8 and having run off closer to 5.5 or below.
Being stoned, and not having the best of eyes makes the shakers not quite accurate enough. Good reference, but that's about all.
If they have a cheap ppm meter I'll grab one too, but I think I've been doing ok on the ppm's so far.
Just tired of this guess game of color when it comes to the shaker.

I'll post some pictures tonight when I get home, hopefully this slightly more acidic sloution I gave her to a healthy 25% run off will help out quite a bit.

Night time temps have been flucuationg, but not to extreme. the lowest is has ever gotten in 62 I believe. Living in CO and the high for the past few days has been 7 degrees and having a bit of trouble keeping the temperature consistent.

Could temperature flucuations of about 8 -10 degrees during the light on cycle cause these issues?
I'll get home and tnet will be at 83 degrees, so I open my outside window to let some cold(very cold -4) air in to cool things off. I'll get the tent to about 75 and close the window over to let things even out. I usually do this two times before going to bed, and when I wake up and the lights turn off it at around usually 78-80)

[Elements001]

Ok, sorry about the somewhat spaoradic reply in my last post. Was at work trying to type it out.

So the temperature is usually at about 78 -80 while the light is on with small fluctuations between 74-82 mainly just after the bulb turns on and as Im getting good air flow through the the tent. Night time temp is usualy about 64-66, has never dropped below 62 (pretty sure that's pretty chilly for them, maybe a bit to mich so.

That and I've been noticing that when the lights are off and my main ventilation fan goes off, I just have a small desk fan that barely moves air thorugh the tent. If I had to guess Id say maybe 20cfm. That being said I've been noticing my RH maxing out at 51% over night during the dark period. I have absolutely nothing running at night except the tiny fan keeping air circulating through the tent. Think thats a bit high for night time and worried about mold so gonna move some things arounf and get better air flow through the dark period.

The nutrients I have been using are all general Hydroponics in Distilled water:
1st) CALiMAGic (1-0-0) 5 mL per gal (just started about 5 days ago)
2nd) FloraNova Bloom (4-8-7) 5mL per gal
3rd)KoolBloom (0-10-10) 2 mL per gal
4th)Floralicious+ (2-0.8-0.02) 1mL per gal

Comes out at a pH of 4.0 or less, so I add roughly 1.5 -2.0 mL of pH up to get to about 6.5 pH. (This has actually been a mistake hte past few times. Learned you want to be in about 5.8 to 6.1 in coco, so I have been trying to get it right on 6.0, but I always over shoot it. Bought more tester fluid today so I can test more and add just like 2 drops after the intial 1 mL and so on and so forth....)

Last night I gave her the same mix, but dropped the calmag because I didnt feel it was helping really. Must've mis judged the shaker color being high and gave her about 5.0-5.5 ph instead of 6.0. Gave her 2 gallons total and the run off was probably closer to 5.0 -5.5 maximum. Think I just kinda threw her in the opposite direction. She's still looking wuite nice, her main cola looks like nothing is wrong with it, as well as about 6 others, but the majority of the rest (6-7 big ones) are being affected much more tha others.



I'm kind of confused why half of the plant seems fine and the other half seems kinda stressed when everything its at the same heig essentially. I'm sure my pH has been going from 6.5 to 5.5 and my plant is not happy with me for it. Will be buying a pen tomorrow or the next day as a double check with my shaker test.

Talked to the hydro store guy and her gave me a couple samples of this SUPREKELP stuff to help. think he said it was something to help with the nutrient uptake in my roots. Not sure if its gonna help this problem, but I dont think it's really gonna hurt.



0-0-1
Soluable Potash (k20).........1.00%
Derived from Seaweed extract
(Ascophyllim nodosum, Sargassum spp, Laminaria spp)

Hopefully I'll get this all sorted out in the next few days before it becomes any more of a problem. It doesnt really seem like its spreading, just kind of localized right now. Wasn't thinking it would really be Mg, theres Mg in damn near everything I use as feed so gotta be pH.
Ph pen time..



On a really positive note though, my 4th out of 5 clones took root this evening. Really happy with these cloning results. Thought for sure I'd kill all of em. The first one has roots coming out all over and I can start to see new growth now. So exciting for me, never had a successful clone before, not to mention 4!

[Elements001]

I also noticed this almost over the entire plant, almost looks like saw blade teeth. Not sure what it was or how to describe to look it up. Really hope I get this fixed here soon. This plant's got so much potential.

[Elements001]

ahhhhhhh, so ok. Light has been about 12 inches away. the stretch slowed down and I kinda stopped raising the light as often as I was. figured out what I was searching for and it appears to be heat stress. So I think I have a minor pH problem accompanied by the light being a little too close, and possibly low RH during the light on cycle (RH usually satsy around 42%)
Raised light up about 5-6 inchees
Turning up Humidifier
Trying to figure out a way to reduce the amount of air flow I'm getting through the tent. Think my 220 cfm fan is too much and taking all the humidity out and stressing her a bit. Don't want to replace it, just somehow reduce the volume of air without burning out the motor or buying a variable speed controller.
Thinking out loud here, trying to keep everything documented. Sorry for over posting or beind redundant, just want to do a good job on this.
Thanks for the input so far all, has been priceless to me

Thats gotta be it man, thank you. I guess I gotta try and keep the temperature more constant and keep the humidity at the desired range for there. Tents probably gonna stay around 78 - 80, so the optimal RH is like 70%, but that's kinda high for flower. Think I'm gonna go for 55% maybe?

[stihgnobevoli]

i dunno wtf all that shit in that other thread was about, but i've been telling you over and over. MAGNESIUM!!!! you need more. you need a lot during early to mid flower. that's why your whole plant is turning lime green/yellow.
