ppfd are light measurements. . I don't do ppm's . I am using TPS organic cal-mag. Its feeding chart says 1ml max for flowering. Also here are my teas nute report . I was thinking of adding a little grow tea(green bag) mixed with bloom (pink bag) to up the nitrogen. What ya think?
Just concerned. Why is the tops of my plants yellower than the bottom fan leaves? I hope the picture shows the true color. It did not use to be this way. The day before yesterday I gave her 1ml per gallon of water of TPS brand Organic Cal Mag. The ph was 6.5. I have been feeding her roots organic bloom tea every 2 weeks. I did raise the light to where they are getting 500 ppfd to 700 ppfd . Was at 600ppfd to 800ppfd. It looks like the yellowing is getting worse every week. Thanks
Growing GSC auto in a 28"x28"x63" Spider Farmer Tent , SF1000 led,Heater between 73 and 79 degrees F. , 1 small fan , Inline duct fan with charcoal filter for exhaust, humidifier running between 55 and 60 RH depending on watering plant. Grow medium is Roots Organic Original . 5 gal Fab pots, Roots Organic Terps Tea (bloom and grow) , Blackstrap Molasses . I stretched her in the beginning , 1st time with leds. I left room in the pot to add more soil in case of this happening . Added soil , lowered and intensified the light. So here is a photographic view of GSC auto's journey!
