Plant trouble, Need help.

[Chabnoc]

I have a Ebb& flow system with 3 plants in it, My plants have been on 12/12 light for about 3.5 weeks. Plant tray is flooded every 4 hours for 4 minutes, just enough time to fill the plant tray for 1 minute, while totally full. I am useing 4.25 OZ of Botanicare Power flower, 7.0 tsp of KoolBloom, and 56 ml of Hygrozyme for 7 gallons of RO water at about 5.5-6.0 PH. Only one plant is looking bad. This trouble is only in the middle part of the plant mainly. Little up top but not much.

Any Ideas on what is going on here? here is 3 photos, first 2 photos are of the bad plant, and the 3rd one is of one ot the healthier plants.

Some of the Bottom fan leafs are turning very yellow.

Any Help or ideas would be greatly appreciated.

If your using RO water you need Cal Mag+ homie.

[Chabnoc]

what is Cal Mag+ do?

[puddlecruzier]

your using to boosting agents and no actual bloom nutes

[Chabnoc]

Can I have this spelled out? :)

I am new to all this.

[Chabnoc]

ok, I just read instructions, and what I understand. PowerFlower is a one piece Flowering Nut, and KoolBloom is the booster. Am I wrong?

[Weedhound]

I use Botanicare products as well but I use the prob-bloom and Hydroplex....i'm not too familiar the "plant power" line. dustko is correct imo...you need Cal-Mag if you use RO water. Cal Mag puts back all the good things your RO system takes out of your water (calcium, minerals, etc) ;) so you can not only spend money to take everything out of your water but also spend money to put things back in.:(

Cal Mag is a biggie. :thumbsup:

[Chabnoc]

Ahhh Crap... Ok.. LMAo

[Chabnoc]

Ok, so I did not have Cal-Mag. And I understand I need to get this, but do you really think, not having Cal-Mag, is what caused my trouble?

[Weedhound]

yes I do. Two of the most common problems are calcium and magnesium defeciencies.....many trace mineral blah blah defs are all prevented by CalMagPlus. Get some asap and start using it.

[Chabnoc]

Ok, Roger that. Will get on that ASAP.

Thanks. :)

In this forum about 1/2 way down page is a thread called Zinc Tox/nute Burn...one of the posts in that thread (by Dutch lover) has a link to plant problems that is excellent. I tried to copy link but I don't think its going to work because I suck at that kind of thing.

International Cannagraphic Magazine Forums - The Complete guide to Sick Plants,pH, and Pest troubles! (http://www.icmag.com/ic/showthread.php?t=11688)

Hope it helps. ;)

[Weedhound]

Cant believe it worked....I'm adding it to my sig.....

[dusto2k3]

weedhound congrats on the accomplishment and the citation is a good one.

CAL-MAG = PROBLEMS:rambo:

[Weedhound]

You said it....I just like to parrot stuff so I look smart...;) :D

[Chabnoc]

Great link WeedHound... Thanks a lot. :)

[Chabnoc]

Ok, read that link you gave, and some other stuff on RO water and calcium and such. Sure am Glad you replied to this Thread, thanks so very much. My plants look exactly like the picture of the plant with the Calcium deficiency. Did a rez change today with fresh PH'd RO water and fresh Nuts. Will add the Calmag tomorrow. Store is closed today.

I also droped my nuts down to just 4 oz's of Powerflower. this puts my PPM at 900. I will leave it at this level of PPM for a couple weeks, then try and raise it a little.

Thanks again for all the help, Dusto and Wolfhound. :smokin:

[Weedhound]

good....glad that helps. Once you put all the parts together and get dialed in you will be able to grow some nice plants.....I'll never buy mj again!!!;)

[dusto2k3]

no worries, good luck!!!

The middle pic... look at the bare streaks down the center of each interveinal region... classic Mg def

[Chabnoc]

ok, got my CalMag+ today, also picked up some Liquid Karma. I put 6 tsp of Calmag and 6 tsp of the Karma into my 7 gallons of nut water. My PPM right now with everything mixed in is at 1300 PPM. It was at 900 ppm with just the PowerFlower Nuts. This sound about right?

[Weedhound]

If you are in week 4 of flower it does sound right. Keep a careful eye on them as you have just introduced something new just to make sure things stay on the up and up.

PS..that Stinky has the eyes of an eagle. ;)

[Chabnoc]

Yes, Stinky. Hydro Store says that My leaves next to buds are rolled under, length wise from lack of iron, and that veins are that way from Magnesium, and the yellow spots are from Calcium. I was useing tap water for veg that I let sit out for 24+ hours. I changed to RO water for the flowering stage, little did I know that I was cutting my own neck. But now that I have my PPM meter and CalMag+, I think I will stick with RO water for now. My tap water runs from 350-700 PPM, depending on the day.

Thanks again everyone for the great help, I am sure that you guys are correct.:)

P.S. I am used to living where Our saying is, "Copper Is Proper". Meaning if you have copper pipes, drink right from the faucet, great water. But this place I live in now, Hmm, well water does not taste very good. Lots of minerals, and who knows what else. I did not want my Buds to have anything to do with water from this state.

[Weedhound]

700 in your tap water!!! Jeez...that sounds more like mud! I love using RO water (w/my CM+) and will never switch back myself.

[Tokudai]

heya, sorry to thread jump, but about Cal/Mag... I use my well water which is 170PPM - the hardness is calcium, magnesium, and manganese - No iron or chlorine or anything.. anyhoo..

Are my plants using the calcium and magnesium from this source, or does it need to be in a different form for absorption. I haven't noticed any deficincies so I assume they are using it, but are they? I asked this once before but got no answers

[Weedhound]

Tokudai when I started growing my hydro guy (who is EXCELLENT btw) told me that I really only needed to use Cal Mag if I went with RO water as most "normal" water has these minerals etc....I too have well water and he seemed to feel that it was not necessary for well water. I switched to RO water because I could not get my ph stable with my well water.....apparently a fairly common problem. :(

If it ain't broke......;) :)

Ps I will never be without my RO water and Cal mag again.... :thumbsup:

[Chabnoc]

Well, the problem seems to not be spreading anymore. That is good.

I took the totally yellow leafs off the plant, but left the ones that are spotted and just a little yellow. This seem like the way to handle this? Or should I remove all the damaged leafs?

Wonder how long it will take till my plant looks normal? If ever. I should be harvesting in about 4 weeks.

I have ready so many people talking about this Liquid Karma, I had to give it a try. Hope it helps as much as people say it does.

Hat off to everyone who helped out.

[Weedhound]

LK is excellent stuff. You may have lost a week or so with your ill plants so you may be looking at longer than 4 weeks. Mostly what damage is done is done....your new growth should look normal but don't expect the damaged leaves to improve. A good rule i follow is if more than 50 percent of the leaf is dead then remove entire leaf. Otherwise just carefully cut the damaged part away from the rest of the leaf.
