PLEASE HELP!!

[stinkyattic]

You're on a res, but in soilless. So automatic drip. What's your res like? Are you oxygenating it with something other than peroxide? Have you been checking the runoff pH out of the pots? I am guessing that if you did that, you would find it to be lower than desired. Something isn't right... obviously, lol. How long since the final re-pot do symptoms typically appear? My hunch is that your lime is used up and you are running low on calcium and the pH has dropped. Along with a stiff feeding schedule, those combine to give the symptoms you are seeing.
But check the runoff pH asap and let us know.

stinkyattic Reviewed by stinkyattic on 05-28-2008. PLEASE HELP!! I am really reaching out here. I have been running into problems late into the flowering for the past year. The same thing keeps happening. The plants look good and slowly over the course of the first 5-6 weeks of flowering they begin to look awful. The main cola, at 35 days almost looks like a its in a bowl ( I will post pics later) with the leaves surounding what once looked like it could have been a bud. The pistils are not developing properly and I have had alot of yellowing of the Rating: 5

Stinkster (and everyone else.....) what about rootbound?

[BeCeLivin]

pYes, You are pretty darn close.

I have a 35 gallon Res that I mix my nutes. I water by hand. They have 2 air pumps with air stones submerged oxygenating the water as well as a regular dose of Peroxide. I added the lime at the final transplant to the 2 gallon pots just before 12/12. It takes about 3 to 4 weeks for symptoms of a problem start to appear. Could I add a tbsp of lime to each pot??

My runoff is low around 6.-6.2. The problems I am seeing could be Calcium trouble. Why would that stunt my flower production.

Right now I am not growing any healthy buds. I have stayed on top of all the basics sprayed for mites, they looked fantaastic through week 4 , then the weather warmed up and things started going SOuth to the point we are at today

If you look really close at the top of the main cola, there are no pistils showing. ANYONE can you please tell me why the flowers have quit developing???

[Weedhound]

The flowers quit developing because the plant is sick. That's what we are trying to figure out.

How about some true specs like room temps, lighting, etc etc. All this info would help a LOT to try and figure out what's going on.

2 gallon pots.....I'll guess rootbound based on available info..

[BeCeLivin]

I am sorry , I thought I posted temps and Lighting.

I was using 10 1000w HPS (ballasts in a seperate room) I have 2 intakes and one outake, commercial size box fan. Plenty of power for the room to clear.

Its in a basement where is remains somewhat cool. Until recently temps on the West Coast in Canada were normal. Cool enough to work that size of a room w/o overheating. Then we had a warm snap. I had a Max day of 95 and another of 91, then I dropped 2 lights. The Max is 85-80F lights on humidity seems Ok starts at aobut 70% when the lights come on, then lowers to 50-60% range.

When the lights are off, temp is 72f-78f and the humidity climbs back to 70% area. I run 6 oscillating fans as well .


The Pics i am sumbmitting are of the main cola tops, as you can see there is no development.

I water by hand when I can lift them with ease. Chemical one day followed by water the next. The runoff has a slight yellow colour to it.


Please if there is any other info anybody may need, please do not hesitae to ask. I am leaning on the group to help me solve my problmems

All right that is exactly what I suspected.
-You may not have mixed the lime very evenly, which can lead to blotches.
-Yup, you are running low on Ca.
-Your pH is causing the worst of what you see there.

I'd suggest adding CalMag to your res and raising the pH of your res water to slightly ABOVE what your goal is, to counteract your LOW soil.

In the future, I'd plan to re-pot 6 weeks from your expected harvest date, to make sure that you are going into that crucial time with nice fresh soil that has a correct starting pH. As your lime buffer is used up, you can gradually raise the pH of the water you dump in there to counteract it. Your RUNOFF number is the very most important one, so monitor that closely.
Here's some reading on the subject- You obviously have a really good handle on stuff already, but people just don't think of how much the properties of your soil DO change over time from the action of water and roots.

Thanks alot

My day is bad already, so I hope this helps

Your time and effort are appreciated

[BeCeLivin]

AM I too late to add Cal-Mag now and save these buds??

[Weedhound]

Never hurts to add but dont know how much difference it will make at this point.

I'm sorry.....did I read this correctly....10 1kw hps....??? 10,000 watts total? Wow!!
