Does Liquide phenol red work to check the water PH?

OneDropOfTHCstarted grow question 4y ago

Liquide Phenol red is the cheapest alternative ive got. It should range between 6 and 8. But it say s for uses at pools and hot tubs, should be more or less accurate and get the job done right? As i can easily see diferences between 6.0 and 7.0? Thank you! :D

If it works, it works. But you can pick up a ph meter quite cheap off Amazon. Similar shopping platforms are available...lol

Half way done week 3 of flower. Just wondering if there are different nutrients I should be adding. I'm using general hydroponics. Just using what it says to on the bottle for feeding. Do the bud candy add that much growth? Blackstrap molasses to water? When? Any advice please?

The pH of the runoff continues to drop below 6.0 with each feed, resulting with me trying to bounce it back every other watering. I would like for the pH to be more stable. Any ideas why this might be happening? I am using Advanced Nutrients pH perfect - Grow, Micro, Bloom.

Hydroponic PPM and feeding. How do I match magnesium sulphate to potassium for flowering??Do I got this right? Hydroponic Flowering cannabis eats at a rate of 1-1-2 and for maximum useage, feeding 1-1-2 makes sense. Extra nutes outside the ratio is wasted and extra. You want highest PPM possible before burning. Will extra Cal-Mag burn roots/leaves?

Terpinator (During Flush or Not)For those of you who use Terpinator, do you prefer using it up until harvest or do you prefer still cutting out everything during your flush? I know its' advertised as being able to use during flush so I'm not worried it's unsafe. Just figured I'd see what my fellow growers like!
