It's cheap and you have at least 5 weeks left, likely 6 or 7. Get some more. A pH of 7 will severely affect what nutrients she can use. If you can't get buffer, you're better off catching rainwater and using that (it's usually more acidic).

Hi!
You can use white vinegar, apple cider vinegar and or lemon juice for ph down.
Use small amounts until you find the right ph.
Happy grow!!!!

it should be, but you can always use lemon juice to lower ph in a pinch, i would suggest keeping your ph where it should be, also if you dont you should be ok until harvest but you do have a little bit to go for that

Should I switch to well water?I use tap water. For our normal flower/vegetable garden we use well water. I measured the EC/PPM of both.
Tap: 0.5 mS/cm (=320 ppm), we live in an area with soft tapwater according to Water Agency (11°F-13°F max)
Well: 0.32 (=205 ppm) -> how do I interpret this for well water?Feeding. Other

How can I improve horizontal growth? -first grow, not too much light, manual watering, no nutrients added yetHey,
I'm growing 2 Amnesia autos, they get around 6-7 hours direct sunlight and I help them out with two lightbulbs. I left them for 2-3 days with not enough light so they grew a lot vertically.
Do you have any tips to increase horizontal growth? (Besides buying better lights :D)

what EC do you feed and how often?I've been giving 6.5 pH water once and the next time I add nutrients until I get an EC of 1mS/cm. This was ok before (runoff didn't show many nutrients on soil). Now I water 2.5L/day but the plant leaves nutrients in soil (runoff EC increases rapidly!) It's in week 4 of flower.5y ago
