Southern lights, Ghost train haze 8, and white fire. The only plants effected are the southern lights.
What was the establishing technique? (seed or clone?)
seeds
What is the age of your plants?
5 weeks veg + 3 weeks flower
How long have they been in the soil mixture they are in now?
3.5 weeks
Were they in the same mixture when they were seedlings/smaller plant? If not, what mixture were they in before?
yes same mixture
How Tall are the plants?
3.5 ft
What PHASE (seedling, vegetative or flower) are the plants in?
3 weeks into flower
What size pots are you using? (Include how many subjects to pot)
3 gallon
What substrate/medium are you using? What brand of soil mixture are you using?(percentage of perlite, vermiculite...etc?)
canna bio terra plus
What brand Nutrient's are you using?
biocanna
How much of each nutrient are you using with how much water? *Knowing the brand is very helpful*
15ml per gallon of flores, 8ml gallon bio boost, cannazyme & rhizotonic
How often are you feeding?
every other watering
If flowering, when did you switch over to using Bloom nutrients?
3 days ago
What order are you mixing your nutrients? (example: veg nutes 1st, bloom 2nd ect)
flores, boost, rhizotonic, then cannazyme
What is the TDS/EC/PPM of your nutrients used?
not salt based, doesn't measure properly
What is the pH of the "RUN-OFF"?
haven't been measuring runoff ph, was told it was not necessary with biocanna
How often are you testing pH/ppm/EC/TDS?
test ph evertime, tends to be 6.4-6.8
What method of pH test was administered? Using Strips? pH pen?
ph pen
How often are you watering?
when the pots feel light, every 3 to 4 days
When was your last feeding and how often are you feeding?
last feeding was yesterday, I feed every other watering
What size bulb are you using?
Gavita pro 1000 on 1150W
How old is your bulbs?
3 months
What is the distance to the canopy?
3 ft
What is your RH Factor? (Relative Humidity)
37%
What is the canopy temperature?
78F
What is the Day/Night Temp? (Include fluctuation range)
68F-80F
What is the current Air Flow? (cfm etc.)
420cfm
Tell us about your ventilation, intake exhaust and when its running and not running ?
fans run 24/7
Is the fan blowing directly at plants?
yes
Is the grow substrate constantly wet or moist?
no
Is your water HARD or SOFT?
somewhat hard
What water are you using? Reverse Osmosis (RO)? Tap? Bottled?
Well water? Distilled? Mineral Water?
tap water, I let it sit 24 hrs before using it.
If using tap water, what is the ppm/EC/TDS of the water right out of the tap?(Only if you have a tds pen)
EC 0.2
Are you using water from a water softener?
no
Has plant been recently pruned, cloned or pinched?
no
Have any pest chemicals been used? If so what and when?
vecto-bac for the past 3.5 weeks (BTI bacteria)
Are plant's infected with pest's?
Fungus gnats, They are pretty much dead now.
It's my first time using biocanna. I was told to run bio vega for the first 2-3 weeks of flower to avoid low nitrogen problems. about 2.5 weeks into flower a few plants started to develop the problem seen in these pictures. It only has effected the lower leaves. 3 weeks into flower I switched to bio flores. The plants still seem to be getting worse. They looked great until about a week ago. anyone know what I'm doing wrong here?
