SOIL:
How long has this problem been going on? Starts showing in flower but I think plants in veg are showing signs too.
What STRAIN are you growing? Whole bunch. C99, Purple kush, green crack, OG cush. C99 is in pics.
What was the establishing technique? (seed or clone?) clone
What is the age of your plants? Think the pics are 3-4 weeks
How long have they been in the soil mixture they are in now? don't know
How Tall are the plants? three feet
What PHASE (seedling, vegetative or flower) are the plants in? flowering
What Technique are you using? (SOG, SCROG etc) none
What size pots are you using? (Include how many subjects to pot) ten inch
What substrate/medium are you using? What brand of soil mixture are you using?(percentage of perlite, vermiculite...etc?) Lamberts
What Nutrient's are you using?GH FloraNova
How much of each nutrient are you using with how much water? This is hard to answer because he just uses a bit of the cap full. i think it is about a table spoon per 10L. Works out to 1100ppmish.
How often are you feeding? Every watering
If flowering, when did you switch over to using Bloom nutrients? Once lights were flipped
What order are you mixing your nutrients? (example: veg nutes 1st, bloom 2nd ect)
What is the TDS/EC/PPM of your nutrients used? 1100ish
What is the pH of the "RUN-OFF"? 800ppm 6.9ph
What method of pH test was administered? Using Strips? pH pen? pH Pen
How often are you watering?Every three/four days
When was your last feeding and how often are you feeding? Last watering
What size bulb are you using? 1000W
What is the distance to the canopy? Two feet
What is your RH Factor? (Relative Humidity) Don't know. LOW probably around 20ish
What is the canopy temperature? Hightest 82F 28C
What is the Day/Night Temp? (Include fluctuation range) Normal 77F/25C day 68F/20C night
What is the current Air Flow? (cfm etc.) Around 500
Tell us about your ventilation, intake exhaust and when its running and not running ? Constantly
Is the fan blowing directly at plants? yes
Is the grow substrate constantly wet or moist? No
Is your water HARD or SOFT? HARD
What water are you using? Reverse Osmosis (RO)? Tap? Bottled? Well water? Distilled? Mineral Water? Tap till now, got RO
Are you using water from a water softener? Nope
Has plant been recently pruned, cloned or pinched? Some topped
Have any pest chemicals been used? If so what and when? None
Are plant's infected with pest's? Nope
The water is around 400ppm with 300ppm calcium bicarbonate. The grower did not allow any runoff when watering plants. He showed me his watering procedures only a little trickle would be allowed to flow out. I am thinking Mg is locked out due to calcium build up. I got RO gave them all a really good flushing then been backing off the nutrients. Watering at 500ppm, using epsom salts at 1/2 tsp per 10L (little over 2 gallons). Foliar sprayed with epsom salts and kelp. No real impovement in the last 4 days. Just want to make sure I am on the right track.
