Team IC, I am on the horns of a dilemma. I am about to lose my entire perpetual cab med grow to an unseen killer. I've read extensively on this and do not want to believe what I am seeing. I really hope that someone can point me in the right direction as I am about to break down and start from scratch.
I grow Top 44, a fast flowering Indica dom and have had numerous successful harvests over the past 3 years--never had one lick of trouble. Reliably produce about a QP every 60 days. The setup I use has remained unchanged for 3 years. I am mostly organic and use the Organics for Beginners soil recipe and have successfully recycled soil the entire time using the 3LB's method. I've never, EVER had problems like this--but my 3 year streak of self sufficiency is about to come to an end.
Some observations: Roots seem to die off and don't produce healthy root structures. Can turn from white to brown in a week. Shoot meristem turns spindly, curly, and gets chlorotic--going to dry and crispy brown during stress (cloning, switch to 12/12, after pruning etc). Seems to mimic a CalMg def. Interveinal chlorosis and mosaic pattern visible. I dissected two plants and their root systems and could not find any root aphids. I know they are small but thought I would see one or two--even under a scope! Out of fear that I had soil bugs I used Azamax soil drenches, this seems to have slowed down the problem over two treatments and the plants seemed to do quite well, but it came right back after cloning.
I've used completely new soil and discarded all my recycled soil-no luck.
Cloning out of it didn't seem to work
CalMag didn't help
Aspirin didn't help
Azamax helped but it came back as soon as I stopped (this is why I
Thinking of trying Imid--even though I can't see bugs.
I hesitate to say that this could be a virus, as I was one of the cynics---but I am starting to feel like this is where I am headed.
First, two gratuitous picture of my last successful harvest:
The pic that's freaking me out:
Chrlorosis/curling of shoot meristem:
Clones after about two weeks, notice the puckering leaves:
Roots of a clone (watered this morning so is wet; these get water about every 4 days):
PLEASE HELP!!!
How long has this problem been going on?
About 2 months
Are you growing in a PVC grow tent?
Cabinet grow, no tent
What system are you running?
Organic soil in SCROGs
What STRAIN are you growing?
Top44
What was the establishing technique?
Clones from mothers
What is the age of your plants?
Various. Problems show up in clones, all the way to veg.
How long have they been in there mixture they are in now?
Various. 1 week to 8 weeks
How tall are the plants?
Various. 4 in-1 foot
What PHASE are the plants in?
They never make it to flowering. Problems appear early/mid veg.
What substrate/medium are you using?
Rockwool cloning to Organic soil
What color are your roots?
They start off white, roots seem to die off, throw new white roots that stretch very far. Die off again.
What Nutrient's are you using?
Guano Tea
How much of each nutrient are you using with how much water?
About 2 TBS of PSG and Mexican, bubbled for 24 hrs with some molasses, LK, and MaxiCrop in 2gals. Solids are then fed and watered into soil
How often are you feeding?
1-2x per month
If flowering, when did you switch over to using Bloom nutrients?
2 weeks into 12/12
What is the pH of the "Tank"?
N/A, soil always seems to stay around 5.8-7 though.
How often are you testing your pH?
Not very often.
When was your last watering?
About 1x per week
What is your water temps?
65
How old is the bulbs you are using?
Change every 6 months
What is the distance to the canopy?
about 1 ft
What is your RH Factor(Relative Humidity)?
60ish
What is the canopy temperature?
75
What is the Day/Night Temp?
75-78
What is the current Air Flow? Tell us about your ventilation, intake exhaust and when its running and not running?
2 ea 165 cfm (Can Fans) running all day all night. Intake through fiber filters, drawn over cooltube and out into filter.
Is the fan blowing directly at plants?
Intake draws fresh air in from floor over filter, past canopy, through cooltube, canopy gets a constant breeze.
Is your water HARD or SOFT?
Normally soft out of the tap. I let it sit for several days before using it in the tea.
What water are you using?
Tap
If using tap water, what is the ppm/EC/TDS of the water right out of the tap?
Do not know
Are you using water from a water softener?
No
Has plant been recently pruned, cloned off of or pinched?
Normal cloning, but this affects all plants regardless.
Have any pest chemicals been used?
Not yet
Are plant's infected with pest's?
Seemingly, no--unless they are invisible!
