Grow QuestionsSoil PH continually dropping after topdressing with lime

Soil PH continually dropping after topdressing with lime

Closet01started grow question 4 years ago

My Soil PH drops fairly quick over the week from 6.5-7 all the way to 4.5/5, is there something I’m missing? I’ve been keeping a close eye on it and adding a few tablespoons of dolomite lime when needed but is this something I’m going to have to continually do or?

When you mix your nutrients with your water are you PH adjusting? If so what are you adjusting to?

As for the dolomite lime, it takes a couple weeks to break down so you won’t see anything right away. You should only have to top dress it once using about 2 tablespoons per gallon of soil.

Dont feed anything now until you see flowers the size of buttons. Then start your bloom nutes. You'll have a lot of nutes in your soil now from overfeeding. Cheers

@gmslave, thanks for the answer mate, I’m feeding by the bottle so will go half rates from now on. Have just started a 24hr period of darkness before hitting 12/12 so will go half rate on the bloom nutes

Yes, if it keeps dropping you will need to adjust. If your feeding your girl by the bottle and not by measuring your ec levels, this is why your ph keeps dropping. Ifmyour feeding by the label, only feed at half the rate. Ifmyour feeding by ec them you want your ec around 2.0 for dirt. Cheers

Should I harvest in 2-3 weeks ?Hey, do you think my plants might be ready in two weeks ? They're autos in 7th week of their life. I know that 9 weeks is ok for most, but these should take approx. 11 weeks. Do you think one more week of feeding, then flush would be appropriate ? Trichomes are mostly milky white

How much time could it be until the plant is ripe?Looking at the image of the trichomes (and ignoring the little black lint xD) can someone give me maybe a rough estimate on how long they could still take? Could it be a week, could it be 3 weeks? I feel a bit unsure because I already see some amber ones too.
