i'm growing 3 white widow autoflowering seeds outdoors, i have a few questions, i bought soil that's 7.5 in ph, which is a bit too high. how can i lower that with house products? like vinegar or lemon juice? and how much do i need? i don't have any ph tester or stuff like that. can rainwater help? i know it's low in ph. also, what does fertilizer do? does it lower ph? i'm also wondering if i should keep my plants under constant direct sunlight. it's a bit hot here. 28-32 C, is that too much?

Soil? What kind of soil? Buy a roll of cheap litmus paper. It’s more than adequate for growing plants. Rainwater requires cal mag added. Keep in direct light as much as possible. If sun only part of the day make sure it’s early morning. This sounds like a slow moving disaster with autos.

If you don't have anyway to test then don't adjust. Your better off with things the way they are. You'll likely do more harm trying to guess how much stuff to add. There isn't just a "one measurement fits all". How do you know your soil pH is 7.5?

wait i didn't quite get you, so they should only get sun in the early morning, not after? also i was wondering, are seeds from an autoflowering plant, autoflowering? the soil i bought is kinda generic, it was kinda expensive so i through i'd be good, i think it's for flowers. i'm not trying to be some hardcore grower, i'm not looking to get as much buds as possible, but just enough to last me a bit

Full sun all day when possible. I’m assuming that soil has nutrients in it. Not the best for cannabis. Especially for autos which can be sensitive to nutes.

Buy cheap litmus paper and adjust your pH to around 6. Do not add nutrients. Not unless the plants show deficiency and I’m betting they’ll burn first from the nutes in it. Just keep going. If the leaves change post good pics on this thread. It will bring it back to the top.

Anyplace selling swimming pool supplies should have litmus paper. Are you in the USA? If so then Lowes or Home Depot should have swimming pool treatment supplies.
