Late flowering ph question

I’m in the end of week 6 start of week 7 flowering

Hydro rdwc

Using r/o water I’m changing out old water for fresh water In a day and I plan to stop feeding the base nutrients.

I’m still using 2 boosting nutrients up until week 8 maybe 9 depending on when they are ready.

My question is
When Should I stop using ph?
Should I continuing worrying about ph levels?
looks like these have another 2 or 3 weeks to go

Yes, keep monitoring and correcting the pH.

I think they have more than 2 weeks to go. Harvest when there are almost no new white pistils showing, and the orange hairs are receding. Use a magnifier, macro pic on your phone, or get a free magnifier/microscope app to take pics. Inspect the trichomes. As a personal preference I like minimum clear, mostly cloudy, about 30% turning amber.

Good luck! Peace

idk man... these girls look kinda stressed out to me... at which level do you keep your PH? it seems like you've overdone it with. just to get me straight: these aren`t maturing colouration on them, they`re nutrient-burned or/and stressed out...

That one pic the top bud looks white..aka light bleached. Plant is def stressed.

Looks like a good 6 weeks of flower left to go.

Ph should be 6.2 in flower. Keep it in that area.

Keep feeding
You aren't even close to the finish yet

I wouldn't stop feeding base nutrients the plant isn't ready, give another 3-4 weeks allow it to ripen then flush it, flushing it before it's ready doesn't make sense to me?

Beat me to it … tops are bleaching

They def are heat stressed they stretched way more than I thought from flowering and I had to move my lights all the way up to the ceiling some even got light burned because they were too close so I turned my light percentage down I keep my ph around 5.8-6.1 e.c was around 1.5 -1.8 during the whole flowering

i believe the pistil coloring is strain related because I have two different strains going pinkman goo and godfather og only one one is like that

Hey idk what nutrient line you are using but i also run dwc( current culture nuts) and at max i feed my plants 1.4 EC, with co2 and my vpd kpa between 1.0-1.5. When running that high EC in dwc you have to optimize everything ( ppfd, air temperature, humidity, water temp) or u will nutrient burn your plants(it does vary with different strains) but try to stay under 1000 ppm ( 700 scale) until u get your environment locked in. One of the good things about dwc is that u can change, adjustand monitor the ppm n ph almost instantly.

And yes 5.8-6.1 is a nice range, always allow it to swing.

It takes some time but you are getting it.

Thats the magic word, man!

I grow on coco and keep the ph in veg between 5.5-6.0 and in bloom 6.0-6.5 also letting it swing

in my experience PH matters more than almost anything... 6.0-6.4 is my range (there are drop offs under 5.8 so i stay a little higher) but near the end of flowering my plants always scavenge and look kinda shit but the buds are good and that's what matters

Looks like heat stress and over feeding. Stop boosting drop your ppms (1.0-1.2EC) and raise/dim your lights. Keep temps between 70-80F and let those buds fill in. And always pH your feed, even during flush.

keep in mind that the plant take up elements in different ph levels and by letting it swing you allow the plant to uptake all nutrients.... The art lays in which frequent you let the ph swing tho
