Have three autos , blueberry , amnesia haze & northern lights. Ff ocean forest, mixed in cavern culture, 1-12-0,and roots organic nitro bat guano 9-3-1, in bottom 2/3 of 5g plastic pots. Ff ocean forest top 1/3. In 30x48 closet Mars hydro 2000 at 80% 24in away. 72 to 75 day 65 to 68 night ,humidity 30 to 44%. 4in 190cfm on high running humidifier day only. Co2 bag 18/6 schedule Two plants look good one not some much. Used test strips for ph at first thought it was ok got digital ,ph to high. Started ph down with vinegar. Fan may have blown humidity on it , over watering,or deficiency?was adding water to keep cool , moved top soil around last night to dry out a little, soil looks dry in pics, but is damp underneath. Last pic shows true color. First pic is AH, then blueberry then Northern lights, After correcting ph issue added recharge by realgrowers, used water bottle with pin hole in cap , to little drops got on blueberry, that’s what that is [image] [image] `[image] [image] [image]

They look fine. Looks like the lower leaves on that one touched the soil at some point. When they do that they burn like that.

Plants look fine. Strongly suggest you discontinue all supplements until plant shows it needs it. You have adulterated the OF enough that you should not touch anything but water until flower (at least). [image] Aaron: Co2 bag Ditch the bag: it does nothing. It’s a waste of time and money. CO2 is only useful at high partial-pressures in an entirely closed loop system with climate controls. Normally done with hydro to push high nutrient loads to take advantage of extremely high light levels. You would need to double or triple your light output to get in the correct range for CO2 FYI. Invest in a TDS meter as well as it is one of the two most used tools available to the grower (and they’re pretty cheap). If you run too high a nutrient load you will stall or stunt plants: something you do not want to do with autoflowers.

First grow , little concerned, wasn’t sure if I should change anything. Thanks!

Yeah seen soil was a little strong for young plants , after I planted. Should I trim those two leaves off? Thanks for info on co2 bag

The last pic is a male plant and should be disposed of immediately. Looks like some of the pollen has already been released so you will more than likely end up with seeds in your weed. Also, when a female plant is pollinated, all flowering energy will be put into making seeds and not buds anymore
