Just keep the girls were the back of your hand doesn't get warm under the light. 16 to 20 inches should be fine. The dual spectrum is great for flower but a blue spectrum bulb is best for veg

Help understanding PH
I have big problems understanding my PH levels. I put in @5.5-5.8 PH (lowered with acetic acid) and the run-off is always too high, about 7-7.5 PH. I started testing my water / nutrients by intervals and nothing makes sense to me. Every test shows an increase in PH, up to 2.7 up?

Male preflowers?
Are these very early male preflowers or is it too early to tell? Can see pistils on other sites but have noticed a few of these lower down the plant but not many.

Sunrise and Sunset Times Civil Twilight
From what I've researched Civil Twilight provides enough lux for plants to sense light, does that mean I'm getting about 13 hours and 27 minutes of daylight?

Opinions needed
I did a successful harvest of runtz muffin and took cuts, now the cuttings at day 18 of flower i noticed balls. This was down to very low night temps 12C and day temps of 26. Now do I throw away all the other cuts I have off those or use them taking more care? Options please👍

Shall I start flowering?
First time I grow, put some auto and some fem, shall I start to flower looking at the bigger plant state? What do you think? I am not looking for crazy yield - if I can get 100grams on average in the fem and 50 on the auto would be more than enough? Shall I pull the switch?

Temperatures stuck at 50 degrees F under the grow conditions tab
Can someone please tell me why under the grow conditions tab, all of my temperatures say 50F degrees? I keep trying to edit it but it just goes back to saying 50F... Anyone else having this problem? I tried it on mobile and desktop and it seems to be glitching out on both.

Drooping Leaves
There is complete drooping of the leaves.According to my research, it 's caused by overwtering.What should I do at this stage?And is the problem really overwatering? I didn't turn it off today because when the lights are off, the plant will droop more.Do you think I did it right?
