Just curious what people might think is the deficiency or problem in these pictures.
they were under a 1000hps flowering and started showing signs of defiencies, even though the soil mixture had lots of organic goodies and they were getting good Super bloom guano teas.
I have had this problem for a while and don't know if it's water quality, Promix/soil mixture or nutrient/ph problems. (Some plants are less affected than others (maybe the less heavy feeding plants?)
The over all problem is the plants turn out smelling and tasting great with great crystal content, but over the curing process they seem to LOSE the taste, potency and smell where it was definitely there at the harvest.
I am thinking maybe a nutrient macro/micro might be building up or locking something out. my water is hard and maybe calcium buildup or lockout?
The problem seemed to increase when I added mylar. I don't think it's heat, always around 78 degrees. Could be possibly the plants are TOO efficient with the mylar? Just sucking up tons of juice?
Thank you for taking the time to read. Any and ALL input/suggestions welcomed and highly appreciated, even if not accurate. I have no clue and it's really frustrating
SOIL:
How long has this problem been going on?
Consistently, some plants affected more than others. Some stay green and healthy, maybe they are feeding less? Others turning yellow with necrotic spots/brown spots (not N defiency) Potentially a regional problem, as I have seen this problem at different locations/different people
What STRAIN are you growing?
all have been affected, some less than others. AK48 for example seems to be less affected, maybe Blueberry too. short, squat indicas seem to be less affected
What was the establishing technique? (seed or clone?)
seed
What is the age of your plants?
already harvested, problem started showing up around 4th or 5th week of flowering. Some of the plants yellowed dramactically, but not N defiency, just an overall pale/greenish look to plant, when they were deep green/even N heavy possibly, then just yellowed up at week 5 in flowering
How long have they been in the soil mixture they are in now?
they were transplanted into 3 gallon containers containing ratio of 3 gallons Pro Mix/perlite/2.5 tablespoons Dolomite Lime/3 Tablespoons Fox Farm Fruit and Flower soil additive (5-6-4 I think, bunch of organic goodies added) Can the Fox Farm make my soil too hot at the rate I am adding? Do my ratios look ok??
How Tall are the plants?
stayed pretty short at 2-3 feet. but it's because they were flowered early. did not seem to get the stretch that I am used to see during the first 2-3 weeks of flowering...low stretch for sure
What PHASE (seedling, vegetative or flower) are the plants in?
flowering
What Technique are you using? (SOG, SCROG etc)
SCROG
What size pots are you using? (Include how many subjects to pot)
1 gallon in veg, and then transplanting to 3 gallon containers around 2 weeks before flowering. One plant per pot
What substrate/medium are you using? What brand of soil mixture are you using?(percentage of perlite, vermiculite...etc?)
Promix. 30% perlite added. 3 Gallons Promix with 3 Tablespoons Fox Farm Fruit and Flower soil amendment and 2.5 Tablespoons of Botannica Soil Sweetner Lime. Should I be using more lime? Am I using too much Fox Farm soil amendment? Does Promix suck?
What Nutrient's are you using?
Fox Farm Tiger Bloom through day 21 of flowering.
Day 21 on through flowering used Bat Guano teas (1-10-0). Teas brewed for 48 hours. Liquid Karma and Meta K also supplimented. Was going to suppliment with Botannica Cal/Mag but never did
How much of each nutrient are you using with how much water? *Knowing the brand is very helpful*
3/4-1 teaspoon per gallon FF Tiger bloom every 5 days when watered, only through day 21 flowering. Ph was balanced with Ph pen
At day 21 flowering, switched to a Guano tea. Tea was 3 tablespoons Jamaican Guano per gallon of water, along with about 1/2 teaspoon Liquid Karma and 1/4 teaspoon Meta K. One time watering with GH Kool Bloom powder at just 1/2 teaspoon
No other nutrients added. Is this enough micros? maybe not getting enough cal/mag or Potassium or Phosphorus with this mixture?
How often are you feeding?
I feed with the bat guano teas every 5 days or so. Would give a plain water every 4th watering or so. So really, there is a period of about 10 days with the plain watering where they are getting by on what nutrients they have. Was it possibly during this time period of plain water that defiencies started showing?
It seems to me possible...because yellowing of ENTIRE plant and brown spots on fan leaves seemed to happen around 4-5 weeks into flowering on most plants during the period where they were getting plain water
If flowering, when did you switch over to using Bloom nutrients?
pretty much right when the light is switched to 12/12. sometimes I continue to use Fox Farm Big Bloom veg for first 7 days of flowering before switching to Tiger Bloom. Too much N? worried about N toxicity
What order are you mixing your nutrients? (example: veg nutes 1st, bloom 2nd ect)
Mixing the Guano first, then Liquid Karma, then Meta K. 48 hour bubble. No foam build up from microorganisms though
What is the TDS/EC/PPM of your nutrients used?
not a clue. never have used one. the best grower I know has never used one ever for soil. should I be concerned?
What is the pH of the "RUN-OFF"?
usually 6.8 to neutral ish, not sure how accurate my testing methods are. Idea of adding dolomite lime being that you can't always be accurate, so it's usually around 7.0 if you added enough. So I typically fertilized with a 6.2 nutrient solution so nutrients are absorbed around 6.2-7.0 range
What method of pH test was administered? Using Strips? pH pen?
Have used both strips and pen, around 6.8 each time
How often are you watering?
Once every 4-5 days usually. Waterings go from dry to moist to dry again, letting the plants dry out. I do not have run off. I am to use low amounts of nutrients/ppm levels that won't allow for much build up in soil when using mostly organics
When was your last feeding and how often are you feeding?
feeding every 5 days everytime I water. plain waterings once or twice during flowering (10 days spurts with no nuts/ferts). My watering seems to be ok as the root system is very healthy, large spagetti roots. Could dry pockets cause my symptoms...
What size bulb are you using? 1000w HPS
What is the distance to the canopy? 2.5 feet
What is your RH Factor? (Relative Humidity)
never above 50%
What is the canopy temperature?
78 to 80 degrees max
What is the Day/Night Temp? (Include fluctuation range)
80 degrees max in the day, 60 degrees minimum at night. bit of a big jump
What is the current Air Flow? (cfm etc.)
Strong Dayton fan blowing air out into attic. So it sucks in air Passivly from other rooms. Big open basement, so CO2 is not really an issue to begin with as a house has a natural air intake/release process. it's not stagnant
Tell us about your ventilation, intake exhaust and when its running and not running ?
Running most of the time. Have seen the problem when it's been running 100% of the time and when not using at all
Is the fan blowing directly at plants?
across the tops to make plants gently blow in breeze. is this bad? have always heard it stimulates them...
Is the grow substrate constantly wet or moist?
maybe a little moist, never wet except for day or two after a watering
Is your water HARD or SOFT?
Very HARD from what I understand. Calcium stains on my bathtub I think, red/orange spots collect
What water are you using? Reverse Osmosis (RO)? Tap?
Bottled? Well water? Distilled? Mineral Water?
TAP
Are you using water from a water softener?
No but I wan't one or a reverse osmosis machine. Which should I get? I personally think the problem could lie in the water potentially
Has plant been recently pruned, cloned or pinched?
pinched 2 weeks before going into flowering. never during flowering obviously
Have any pest chemicals been used? If so what and when?
No
Are plant's infected with pest's?
No
