Hey. Was Reading a bit of your discussion and 9 plants is possible under 1 600w with a good yield. I did use 15 liter airpots and got 620 grams. That was my second grow ever. Have a look how I did. Wish u the best of grows man!
Hey! How Much water do u give Them? Im just on My Third grow But My eyes tells me i Would give Them more water. The soil looks very dry in the edges. Almost Dusty. Now i cant Put My finger in your soil to confirm it so i can only go by My eyes. But they look healthy, no question about it. Im not really sure about My nutrients so i cant help u about yours. Hopefully someone With the skills Will Answer all u want to Know about your feeding.
