HTG supply air cooled reflector
Plantmax 400 HPS bulb
Lumatek digital dimmable 425/400/275/250 ballast
How long has this problem been going on?
2-3 weeks
What STRAIN are you growing?
sour cream
What was the establishing technique? (seed or clone?)
seed
What is the age of your plants?
16 weeks 4 weeks flower
How long have they been in the soil mixture they are in now?
8 weeks
Were they in the same mixture when they were seedlings/smaller plant? If not, what mixture were they in before?
same
How Tall are the plants?
SCROG throws off height
What PHASE (seedling, vegetative or flower) are the plants in?
flower 4 weeks
What Technique are you using? (SOG, SCROG etc)
SCROG
What size pots are you using? (Include how many subjects to pot)
6 gallon square garden container
What substrate/medium are you using? What brand of soil mixture are you using?(percentage of perlite, vermiculite...etc?)
FFOF 2/3 perlite 1/3
What brand Nutrient's are you using?
Fox Farm Trio half strength
How much of each nutrient are you using with how much water?
following schedule to a 'T' at half strength 2 liters water
How often are you feeding?
every other day
1. just water with nutes
2. just water with 3/4 tsp molasses
3. nutes with molasses
4. 3 liters plain water just enough to get runoff to check ph/ppm
If flowering, when did you switch over to using Bloom nutrients? fox farm schedule
What order are you mixing your nutrients? (example: veg nutes 1st, bloom 2nd ect)
dont follow this one
What is the TDS/EC/PPM of your nutrients used?
varies from 7.2 - 7.6 attempt to keep runof between 6.5 and 7.0
What is the pH of the "RUN-OFF"?
latest was 7.0 with 575 ppm
back in veg runoff was 5.8-6.0 so i started to put higher ph'd water to get the runoff up so for last 9 weeks my feed water has been 7.2 to 7.6 depending on the day, even though my runoff has never been higher than 7 is it possible to the high ph feed water has been a problem?
How often are you testing pH/ppm/EC/TDS?
always ph/ppm feed water, runoff checked every 8 days
What method of pH test was administered? Using Strips? pH pen?
digital ph pen calibatd monthly
How often are you watering?
see above
When was your last feeding and how often are you feeding?
What size bulb are you using?
400 w plantmax HPS
How old is your bulbs?
3-4 months
What is the distance to the canopy?
was 8-10 now 15"(attempt to lower stress)
What is your RH Factor? (Relative Humidity)
very low 20-35
What is the canopy temperature?
77-83
What is the Day/Night Temp? (Include fluctuation range)
here is the problem has gotten down to as low as 59 some days i moved my tent to a warmer room could be almost 30 degree difference night and day i think hats where the trouble started
What is the current Air Flow? (cfm etc.)
cap 6' fan with speedster on low
Tell us about your ventilation, intake exhaust and when its running and not running ?
6' phresh filter exhausted thru a 6' air cooled reflector runs only when lights on
Is the fan blowing directly at plants?
small clip fan yes
Is the grow substrate constantly wet or moist?
no, i water just enough that it is dry enough for another watering 2 days later
What water are you using? Reverse Osmosis (RO)? Tap?
Bottled? Well water? Distilled? Mineral Water?
tap
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)
7.4 99 ppm
Are you using water from a water softener?
no
Has plant been recently pruned, cloned or pinched?
no, started with 4 way lst and lst' the 4 mains a few times way back in veg
Have any pest chemicals been used? If so what and when?
Are plant's infected with pest's?
no
the plant has looked like it has sunburn right under where the bulb is for a while so i kinda ignored that
i was goin to do a major flush last night and took it out of the tent or the first time in 3 weeks and couldnt believe how much worse it looked under regular lighting the HPS covers a ton of the discoloration and makes it look much healthier then it is
last night i was do for a new watering starting week 9 nutes
what do i do? flush and restart the feed schedule?
can this pant be saved?
i already moved the tent to a warmer room in the house to avoid the extremely low lights off temps
if you notice in the one pic under the canopy sems much healthier than the tops, is that due to the cold?
