What Technique are you using? (SOG, SCROG etc)
None
What size pots are you using? (Include how many subjects to pot)
Currently in 3" coco cups.
What substrate/medium are you using? What brand of soil mixture are you using?(percentage of perlite, vermiculite...etc?)
Pro-Mix Seedling Mix with 20% perlite added.
What Nutrient's are you using?
Fox Farm Feeding schedule started at half strength during 2nd week.
How much of each nutrient are you using with how much water? *Knowing the brand is very helpful*
1/2 Strength
How often are you feeding?
Only fed once to see effects, which started yellowing and browning 2 days later. Not fed since.
What is the TDS/EC/PPM of your nutrients used?
6.75
What is the pH of the "RUN-OFF"?
Not measured yet.
What method of pH test was administered? Using Strips? pH pen?
pH Pen
How often are you watering?
Once per day when the soil drys out.
When was your last feeding and how often are you feeding?
1 week ago, not since then.
What size bulb are you using?
6x54w Fluoro
What is the distance to the canopy?
4"
What is your RH Factor? (Relative Humidity)
45-55%
What is the canopy temperature?
75-79F
What is the Day/Night Temp? (Include fluctuation range)
75-79F
What is the current Air Flow? (cfm etc.)
Not measurable, two 4" muffin fans.
Tell us about your ventilation, intake exhaust and when its running and not running ?
Ventilation running 24/7 with the bulbs to keep the area cool.
Is the fan blowing directly at plants?
Blows above the plants for a slight rocking in the plants.
Is the grow substrate constantly wet or moist?
I check it twice a day, at the 12 hour mark its still moist on top at the 24 hour mark the soil is dry top to bottom.
Is your water HARD or SOFT?
Soft (Filtered)
What water are you using? Reverse Osmosis (RO)? Tap? Bottled? Well water? Distilled? Mineral Water?
Filtered Tap Water that's been bubbled.
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?
No.
Are plant's infected with pest's?
No.
Ok, that's out of the way. Since I added nutrients to the soil a week ago I have not added anymore, just keep adding straight water every 24 hours. The pH of the water is 7.0 on the dot.
At first the tiny round leaves all turned yellow which I thought was normal, then the next set of leaves up turned yellow and now brownish, and the leaves above that are starting to turn yellow as well.
The pics are abit out of focus, but this is happening on about 30% of the plants.
I noticed some of the plants had a purplish main stem and others had a greenish stem. I don't know if that indicates anything.
TIA,
