Leaves turning yellow purple day 40

Growing in sunshine mix 4. I feel like I haven’t been feeding heavy enough but who knows. Any input? They are on 40 days into flower

Added two more pics

very pretty. Judging from the leaves in the background i don't think you're overfeeding by much if it all but maybe could start to slow it down. Purple is genetic and yellow is the plant maturing. Just keep doing what you're doing!

The tops are fine. It’s only like 4 plants this is happening. I see a few more starting to turn slightly yellow. Just wondering if I should up the feed or let it ride.

My first grow so I honestly have no idea lol

I would let it ride. Your flowers look very developed for day 40. The leaves are gonna yellow at this point regardless of feed the plant is almost maximum maturity so its getting ready to die. You're really close. Some people would say you should start flushing already.

I would just keep doing what you're doing. Are you feeding with a chart or a TDS meter?

I am using advanced nutrients grand master bundle, at like 30-40% strength every feeding which is every 2-3 days. The guys from advanced say the issue is not enough food. When I mix at 30-40 percent I get 1000ish ppm.

Yes I have a ph and ppm meter and everything.

I thought the dosido I am growing is a 9-10 week strain. I was going to feed another two weeks and then feed 10 days with water. I haven’t even got to use the bud factor x and overdrive yet.

1000 ppm is plenty! especially at every feed. I wouldn't go over that.

Could be a 9-10 week strain and nothing wrong with letting it go as long as possible. Sunshine mix is an inert medium so I wouldn't worry about a 10 day flush personally. 3-5 days (2 irrigations of pure water) is more than enough for soilless (inert) medium imo. I'd give it whatever additives/bud boosters you want with the next irrigations and then maybe reevaluate where you're at. If you have a x60 magnification loupe you could take a peek at the trichomes and see if any are ambering. But overall, you're getting close. You should see the immature buds people post on here thinking they are done! Yours are at least smokeable at this point already.

So, Well done!

Well yesterday when I checked the runoff ph and ppm of the plant that has purple leaves the ph was 5.4 and the ppm was 2700. There’s a few plants in hard to reach spots so I sometimes slack with watering until enough runoff.

Yesterday I ran tons of 1000 ppm nutrient solution through them until the runoff was 1000ppm and ph went back up to like 5.9/6.0. I would say I ran 150 gallons of ro nutrient water@1000ppm hrough 32 3 gallon pots. Well now today there are a few more leaves that are starting to turn yellowish. I never have flushed with water I always flush the salt build up with nutrient water if I somehow manage to get buildup by not watering until enough runoff.

I just feel like maybe I flushed too much out yesterday and didn’t replace enough? Should I let them dry out and feed again next watering or maybe just give them more food ASAP?

Just really trying to figure out if I need to feed now, Foliar feed now, or just let the soil dry out and feed again next water in 2-3 days

Post some pictures of the whole plant if you can.

I would just let the mix dry out a bit and continue with your 1000ppm next feed. As long as they have 1000ppm they are not underfed. The yellowing is natural for this phase of life. By the time the buds are ready most the leaves will be completely yellow. I think your plant is just finishing a bit sooner than you were expecting!

I wouldn't worry! Continue feeding at 1000ppm with your regular schedule.

Don't worry about runoff pH. Its good you checked runoff TDS because 2700ppm is too high. Personally I feed at 800ppm and runoff is usually 1000-1200ppm and i hardly ever see any deficiencies. It is important to get 20% runoff with these soilless mixes to avoid the salt build-up, like you say.

I would not foliar feed. Keep the dense buds dry. Getting them wet can cause mold even with good environmental controls.

No more food, your soil and roots have enough nutes in them for the 20 day's or so left until finish

Whole plant

Very nice plant. Overall the dark green leaves could be a sign of overfeeding. Its definitely finishing up soon. I would not worry about feeding it more right away. You could probably get away with water from here on out. If you want to give it those bud boosters, just reduce other elements of your feed so that your total feed is not more than 800-1000ppm. The plant doesn't need any more food at this point. I agree with Jim that it will be done in under 3 weeks (maybe sooner) and you could probably get away with water only from here on out, based on the look of the plant.

The yellowing and purpling are both natural and unavoidable now.
