I am having some root problems. I wonder if anyone can help me.
I have been growing with Nutrient Flow Technology for over 20 years now. NFT always produced enough medicine to meet my needs but now I see that I am not maximizing production and have started to try and get a better product.
The plants in the first photo were clones and were under 18 hours for about 5 weeks when the photo was taken. The plants to the right (Four Way) are ready to go to 12 hours at about 20 inches in height. Two of the plants in the background of the other columns are almost ready to go to 12 hours. Six of the plants (mostly Lavender) just didn’t take off. Examining them closely the roots have never started to grow out.
Out of 12 plants two or three usually don’t do much as others get a faster start and the roots crowd out the slow pokes. I never paid much mind to the slackers as the others made up for them.
This grow over half the plants are slackers.
I am wondering if anyone can offer any advice. I have inserted a picture of one of the plants with poor root growth. This plant has been under 12 hours for six weeks now.
The roots all smell good. I don’t know if the brownish color means anything as all the roots usually end up with this coloration. The plants in the right column have new roots that are white and older roots that are a little brownish which I have come to expect.
Started my grow with Greenleaf Logic Grow. After about three weeks when I noticed the plants had not taken off I switched to GH Flora grow.
I am running tap water and a TDS of about 1,000 after subtracting 240 TDS for the tap water. I am paying careful attention to pH and the temperature is good.
