No bud mass but some lower white hairs already turning orange?

Plants don't look far enough along yet to have any bud, hairs will start to initially appear along the stems, each hair takes a reading of surroundings taking Into account of available light, if plant decides there is enough light to warrant a bud site it will grow one from the little hairs sac, some will spawn clusters, some will turn orange and simply won't develop any further as possibly the light source was moved further away or foliage was too dense. When plant shifts to flower the time goes from 18 hours to 12, doesn't matter so much with autos I guess, but flowering does require higher levels of light generally speaking. Plants look good and healthy. After 4th week of flower you should have a better idea of final size, she looks like she just started flower tbh.

could be wind burn.. that'll kill pistils with exposure. spray any stupid shit on your plants lately? That too could do it. pistils shouldn't be dying right after they are developed- you are in early flower. your fertilizer and water isn't the cause unless you are spraying it on the pistils. check again for hermie, as pistils die after pollination too.

Don’t stress it homie the plants look healthy. If the ph was to low the plant would be getting lighter by now with spots. It’s pretty normal some random hairs will turn brown randomly. You most definitely on the precipice of the plant really starting to flower. Your plant is starting to come out the stretch phase. I would say you plants are right around day 20 of flowering. Make sure not to chop down to early you have a good 5 to 6.5 weeks left until harvest. Always remember buds fatten up the most the last week or so during flower. If you chop down 1 week to early you can lose 40% of the plants potential. Buds shrink a lot when they dry. They will shrink way way more if cut down to early

Hi, also wegen den buds,ist es normal das sich einige härchen schnell Orange oder braun verfärben. Das sie noch nicht dicker sind ist auch normal das dauert halt etwas. So aber wenn du jetzt von braunen Flecken sprichst, die sieht mann nicht auf deinen Fotos, so wie @organoman sagt wären ein paar bessere Fotos hilfreich. Aber diese flecken könnten schon zu Problemen werden. Denn Rostig-bräunliche Markierungen auf den unteren Blättern von Cannabispflanzen können auf verschiedene Ursachen hinweisen: pH-Wert-Schwankungen: Ein unausgeglichener pH-Wert im Boden oder Wasser kann die Aufnahme von Nährstoffen behindern und zu solchen Symptomen führen. Daher solltest du dein Runoff kontrollieren und der PH wert solte zwischen 5.8 und 6.5 liegen Überdüngung: Zu viel Dünger kann die Wurzeln schädigen und braune Flecken auf den Blättern verursachen. Dazu wieder Runoff kontrolliere und nicht nur PH wert sondern auch den EC wert der solte nicht über 2 liegen. Wenn beide Werte ok sind dann kann es auch ein Nährstoffmangel sein warscheinlich Mangel an Kalium, Magnesium oder Phosphor kann solche Verfärbungen hervorrufen. Diese Nährstoffe sind essenziell für das gesunde Wachstum der Pflanze. Also lade doch ein paar mehr fotos von den Problem zonen in dein Tagebuch/frage und überprüfe die oberen Punkte

No they look happy to me.. leaves up and looking good.. be patient the buds will come in time...

They hardly grown into flower. Give it time. stuff turns brown all the time. they get damaged easily. Leaves might be from overfeeding or under. hard to tell with them pics. do not see any signs of underwatering.

hairs can change colors from too much wind or accidental pollination. the rusy brown marks can be from not dechlorinated water and/or calcium deficiency. depending on how they look (inbetween veins, edges of leaf etc.) though it could also be a phosphorus deficiency
