Do auto flower at any time and any kelvin ?

Just woundering if autos flower even with 18/6 lights schedule and 5000 kelvin or 2500kelvin

Auto flowers will start to flower based on age rather than photoperiod. Color temperature doesn't really affect whether a plant flowers or not from what I gather. However higher kelvin is better for vegging and lower kelvin is better when flowering. That doesn't mean you should leave either spectrum out, but it'll probably be better to use a higher ratio off blue lights in veg and a higher ratio of red spectrum lights in flower.

Ah ok thanks buddy

Can I use oranges to Make ph water to 6.3 cause tap water has ph of 7

Yeah I heard citric acid or lemon juice is alright, but phosphoric acid is better. As long as it's around the right pH neither should hurt.

You can find pickling citric acid like this at grocery stores for 6-7 dollars. I think it has like 1% sodium silicate for anti-caking purposes, but other than that it's 99% citric acid.

Ah ok thanks yea it's 6.4 the ph max 6.8 with oranges
