Ebb & flo Yellowing leaves inside out {PICS}

[BigGreen]

Ebb & flo 5x5 square pots with 1/2 inch of coco slab in bottom filled with hydroton, nothing in the tray. 2 floods lights on. Ro water. 600 ppm floranova grow, 150 ppm dry koolbloom, 150 ppm calmag plus and floralicius plus a total of 900 ppm. 600 watt hps on light rail in 3x5 room. 1 little fan on plants and 1 4 inch canfan pushing into a canfan filter ouside of room. 1 1/2 weeks of 12/12. It started a couple of weeks before I switched the lights to 12/12. Im not sure what it is. I know the nutes are high right now but I will bring them down to 700 ppm tonight. Heres some pics any help would be very kind. PS I just started the calmag plus 4 days ago. OH YA my PH is 5.9 I bring it down to 5.5 then let it rise to 6.2 repeat.

when a plant is growing fast and happily, the chlorophyll hasn't had a chance to catch up. one clue is to look at the overall plant, leaf color - top - middle - bottom, and specailly leaf tips. your plants appear to be very healthy, so i will say they are happily growing and not had a chance to chlorophyll up.

 

[BigGreen]

They look very unhealthy to me. The growth slowed in the stretch when it should of been picking up I got no stretch when usually I get about 6" to 8" I got 1" and that sucks. Something is wrong here and I dont want to just start dumping out 25 gallons of nutes and start adding stuff just to dump it again. Ive been trying stuff and nothing worked yet. Ive done this strain for the last 6 months with out problems in dwc. I just switched this grow to this ebb & flo and I cant figure out what it is.

Assuming room temps are the same as DWC (and you used the same nutes?) then I would say they need to be watered more. But I don't use Flora Nova, I'd use a lot more Calmag, but don't know enough about Flora Nova nutes to really say. Sorry...no real help either. Good luck.

My only real advise would be when in doubt, flush, decrease nutes and increase aeration.

 

[BigGreen]

Room temps are a high of 78f and a low of 68f

I would say some sort of micronutrient.

Sulfur or Iron

just my $0.02

 

[cocktail frank]

they look overwatered to me.
but what do i know about dwc?
nada

 

[BigGreen]

Its ebb & flo and there not over watered they were getting 4 watering now there only getting 2 and they perked up. Its the color of the leaves look closely at the pics you can see all the yellow.

 

[BigGreen]

Thanks for the help and consideration out there. These things have been pissing me off since the start theyve been really stressed tryin to work out kinks in the climate but there all worked out now so hopefully they turn around.
Weedhound thats funny because everybody else tells me there overwatered

 

[Weedhound]

"they" could well be right but two things in my defense. One hydroton is extremely "airy" and does NOT hold large amounts of water for large amounts of time. That's why it worked so well with you DWC....the plants had access to their water whenever they needed it.(with root/water access 24/7..) Now this has changed Twice a day just seems low to me for hydroton which is usually used with systems that run a drip or dwc/....a 24 hour system. If you are running rockwool inside the hydroton I could be off course altogether and THEY could be the right advice to follow.

Good luck.

 

[BigGreen]

Thanks I just lowered my ppm to 650 and Im gonna let them babies take it easy untill they show some progress

Do a search on the "Lucas Formula". Follow his advice using ONLY the Flora Nova and nothing else. Your to early on the Kool Bloom dry (it is for late flowering) and I don't see why you need the Cal/mag. You cannot over water in a DWC. I use GH but not the Nova line........I think you should switch to Flora Nova BLOOM. Your plants are developing buds and the Nova Grow won't have what it needs during bloom. At this stage of the game I have my PPMs at 1300..........BUT I am using the Lucas Formula. Try it........Its just way to easy and will take the guess work out of the whole thing.

i agree with weedhound also. Hydroton holds pretty good moisture but you need to water pretty frequently. Depending on a couple of things: Age ; Temp ; humidity, and system im sure there is more but i can't think of em. You probably already know bout age & temp so humidity and pretty big. I live in a area that has very low humidity with in turn makes me water more frequently then other people. Some ppl flood every four hours I flood every 2.75 hours. never seen any signs of over watering.(with a ebb n flow that might be a good thing as the plants see nutes more often.) when i was using the tables (now i ebb n grow in the buckets), i always kept my res highly aerated with a addition pump stirring the res at all times. didn't see anything about that you could already be doing it. just in case. and keep that res cool just like with dwc the plants love that. and it's sometimes tricky with them table but cover them roots if need by i learned the hard way. good luck buddy!

Thanks Smoke......you know great minds think alike, right?

Pirate, Is Flora Nova the nutes that you don't really need CalMag with? I know there is a least one set or line that doesn't need CalMag to be complete but I'm not sure if it is the Flora Nova line or not.

 

[Hydro-Soil]

Ro water. 600 ppm floranova grow, 150 ppm dry koolbloom, 150 ppm calmag plus and floralicius plus a total of 900 ppm.

Have you ever done a comparison run of just Floranova Grow and then Floranova Bloom, to see what your plants look like without anything else?

The Floranova series already has enough cal/mag in them for use with RO water. What you're adding might not be hurting, but you may have an easier go finding a balance without that in the mix.

Give the straight nutes a shot first if you haven't already. They have a very professional mix of additives already in them for cannabis. You just might be surprised.

I believe HS above answered the question.

Here is my thoughts based on my own personal experience:
I have never found a reason to use Cal-Mag. It seems that everybody and their mother uses it and suggests it. When I read in the Infirmary about peoples plant troubles..............The answer always seems to be...."Use Cal-Mag" and it drives me crazy since that's usually the wrong answer. I believe this should be a last resort and then only after being absolutely sure it's even needed. I'm not saying it's never the answer. Just not near as often as the general populous seems to think

You can usually fix a Mag deficiency IF YOUR IN HYDRO by raising your PH levels to 6.0 / 6.2 later in flower. Mag becomes more available at those levels. This is how I deal with it and it works everytime. You will rarely if ever find a Mag Def in veg. I never have.

The fewer products you can put into your rez the better off your gonna be. That's the whole concept behind the Lucas Formula. Less is more.

Hope that gives ya something to consider.

HE certainly did and a I missed it. Thanks Hydro Soil

Thanks alot guys much appreciated I gonna dump out the res and start fresh. I was just going with the nova grow for the transition for the stretch. Them babies are afghani and white widow and theres no stretch on these ones. Im pretty sure I was locking out the mag. Earlier in veg I was getting the drift 5.5 - 6.2 but closer to the flip I was over furting and my ph wasnt getting over 5.9 and was sinking. So when I run the lucas do I still give it a bump of florilicius plus like week 4 or 5 for frostyness . Is it gonna be fine to add the liquid Koolbloom also. Thanks again for the help

 

[BigGreen]

I know what the problem is. I pulled one of plants out of the 5x5 pots and it was totally root bound and wet. I think there starting to get root rot. Anybody think if I put down a bed of hydroton and cut out the bottom of the pot set in that or just transplant into bigger pots. Im gonna add aquashield also. I think the culpret was the 1 inch coco slab in the bottom of the pot holding the water. I put it in there so the hydroton would'nt fall out of the holes. Any other suggestions would be great help
