That looks like a Nitrogen deficiency. When Nitrogen falls off in flower, the fan leaves are the first to show it. Very common for soil growers and hydro growers alike, when switching to flower, to cut off nitrogen too soon. I grow in hydro but in soil the same process has to happen, just applied differently. You need to have a supply that will dwindle down over the first 3 weeks of flower. This is because the plant still needs some nitrogen but in lessening quantities as it goes deeper into flower.

You did the best thing by adding some veg nutes. However, we don't like doing it that way as it can give the plant a quick "burst" of nitrogen, which can interfere with the chemical processes that govern flowering, thus causing the flowering phase to "pause". That wont necessarily hurt the plants or the flowering but it will cost you in flowering time, and possibly some (herm/nanner inducing) stress.

I don't know how much you added to them, not a lot I hope. If it was just enough then you likely wont see any issues. But the deeper yellowing leaves will die off at this point. Adding nutes late in this case wont help the yellowing leaves. But it may slow the "yellowing off" of the rest of the leaves until you are closer to finishing.

Good thanks again for your response [emoji482]

Yup, what he said. Different plants take up nitrogen at different levels, even if from the same strain. I feed my vegging supplements up into the 4th week of flower with some strains. :vap-Bong_smoker:

They look good for starting their 5th week. Its not surprising that you are seeing dying pistol hairs as those were the first ones. The buds should continue to produce new hairs for a while. When the buds quit producing new, white pistol hairs then they are going into what is known as senescence (aka old age), that means you need to start watching the trichomes for milky/amber ripeness. I like to get as much milky/cloudy trichs as possible while not going over about 10% amber. I generally shoot for about 5% amber (eyeballed guestimate)

Yeah its not surprising that they have clear trichs at this point. They should have at least 3 more weeks to go.

[Bronsonwillner]

has anyone tryed to dry buds outside in a box in the dark if the temperature and humidity is good ? With a fan in the box to move the air ?? 10x

 

[bubba887]

I wouldn't see why not but keep an eye on weather and surrounding stuff

22 degre celsius 50% humidity ?? In the day (box to be dark a mini fan) and a lot of atention the bud could get to dry to fast ?

Your plants look a little beat up but yes they look normal.
