Anything around the house i can use to lower ph levelz. And how?

Hi, finally got all the gear together and am attempting to grow my first plants I thought things were fine until 4-5 days ago when the morning Ph seemed to about 3 levels lower than than the night before (5.8->5.5) I raised it back to 5.7 but 12 hours later it was back at 5.5. The problem has become more extreme with drops from 6.0 down to 5.2 over a ten hour period (8 of which were dark) and today from 6.2 down to 5.3 over the course of 11 hours (no lights partial daylight due to power outage).

Hey all, It's been about a week since I've first posted. The plant itself looks to me as if it's coming along nicely, except for one thing. That cheeky little thing sitting on the plant thinking he owns the place. If I'm not mistaken it looks like a whitefly? Any ways of getting rid of them that worked for you? I seen somewhere that Ladybugs will help, so I might try that. Keen for your input, cheers.

My 4 week old white skunk has it's lower leaves turning yellow?

Hi guys i have had this grow going for about 3 weeks in a bubble ponics setup seems to be going fairly well for my 2nd grow ( first was a failure [emoji17] ) just wondering if i have had my lights to close cause it seems to be fairly short dense and bushy. I have had the lights (a 130watt cfl) roughly 6 inches away for most of the time. Just wondering if i should of had it a bit further away l.the position of the light in the last pic is where i moved the light to now.

I may have a dude plant look below.

Hoping someone can offer some advice, I'm growing 1x plant in canberra Australia in a pot on the balcony. She was planted in early December and thus far has been flourishing. Her only issues are browning on some of the new leaves, a general pale leaf colour, and tiny white dots on the leaves. I have no indoor setup and Canberra is pretty dry. She's stored under a shade cloth for the last month after someone told me she may get sunburnt. No idea as to her strain. I think she's starting to flower and am looking to ensure her success. Thanks for any advice!!
