Stunted Growth, minor deficiencies

fxh · #1 (**permalink**) 10-06-2009, 09:38 AM

I'm doing an aeroponic spray system, which should have fast rigorous growth-- but my plants are all really stunted. There are some minor nutrient deficiencies as noticed on the leaves but otherwise healthy roots, branches and stems, and new growth. Its very bushy, but very short. Everything else looks more or less healthy. Plants are about 4 weeks old. I do use tap water, this maybe an issue as well.

Here are some pics:

And here's the setup:

Any ideas you can tell? not enough light?, temperature?, certain nutrients?

Please advise

What is your ph? I`m not sure exactly what the problem is, they look pretty good. I can see some minor defiencies in the leaves. Like I said I`m not quite sure but I`d post ph and maybe some1 can help. I posted a thread in this section titled self diagnose your plants that may help you. Be forewarned tho its kinda long, but if u hunt and search it there is good info. all thru it. Hope it helps

Yeah, I've seen many posts and charts on the subject. I increased the magnesium levels as that is what It looked closest to.
PH is always around 5.7-6.3

I`m sure you already did or already know, but make sure to check your ph always b4 you add anything to make sure that your plant is properly taking in said nutrients. If not a could be onsetting of ph lockout. Like I said I`m sure you checked but just in case

I have a digital ph monitor that runs constantly See the setup pic. I check the ph multiple times per day and adjust it to 6.1 and then let it fall naturally to 5.7, then I push it back up again. It takes about a week for the ph to fall to 5.7

I had salt build up in during the first week or so of vegging caused by using the wrong kind of ph up and down, that problem is now fixed.

hi dude are you letting the tap water sit out uncovered for atleast 24 hours before using it? as this lets the clorine & crap evaporate out of the water making it safe to use, also what are your temps running at?, plants look healthly tho real nice short & bushy

fxh · #8 (**permalink**) 10-07-2009, 05:09 PM

No, I haven't been letting it sit. I should be tho, I didn't think about that. I need to buy another tub so that i can clean by waiting. Temps are around 75 low 87 high.

I mean for my setup, i'd prefer short and bushy. It gives me alot of room to grow with. but I need them to be taller so i can lst or scrog them.

Ill post some new pics tonight, they have only gotten bushier since, lol. I moved the lights up so it would start stretching trying to get taller that way but only the leaves starting stretching which was not what i wanted but made sense from the plants perspective.

I shall start using tap water that's cleaned by waiting 24hrs. Thank you.

yea that could have been the problem, make sure when u leave the water out its uncovered like in a bucket or something, also if you can keep your temps under 80 that would be better, so theres less fluctuation in temps.

I will replace the water this weekend. I'm letting them flush the nutrients out of the current water bin until the weekend to also re-organize the wires and get sites ready for clones, create a light seperator to have flowering/nonflowering. Get all the changes done at once with minimal affects on plants.

If chlorine or whatever is in my tap water stunts their vertical growth, I might just repeat that process with the next batch because as it looks like so far the water is only affecting height not actual plant growth of leaves, # of branches, etc. I want to see the bud before I repeat this but if all's good, then I have a way to truly maximize yield, in addition to lst or scrog within my setup.

New pics later tonight. I used some twist wires to create a 'canopy' that exposes the old leaves to light and new top growth as well. I then moved some lights lower so that new undergrowth can get a lot of light much earlier. I think its working pretty good for that plant.

Also, thanks for all the help now and in the future

What do you mean by the wrong kind of PH up/down? I didnt know there are different types?

fxh · #12 (**permalink**) 10-08-2009, 06:58 AM

The ones that are meant for pool supply. Sodium carbonate and sodium bisulfate cause sodium salts to buildup in the water supply and lock out nutrients from your plants. After doing research I found that Sodium is pretty bad for plants. The salts increase the more you adjust. It usually took a good amount of ph up/down crystals to lower the ph as opposed to the ph up/down concentrate I now have which takes drops and lasts a long time and recommend.

Here is the pictures of the undergrowth with a 'canopy', whatever.

Thanks for all the help. The plants have recovered and are doing very well.
I have begun cloning. Everything is a-ok so far.

Looks like my problem was solved by using cleaner/purified tap water, switching to proper (non salt) ph up/down.
