Hello mate, looking your plants this porblem seems to be linked to immobile nutrient, like Mn Zn Fe. Normally all problems that come from immobile nutrients start showing in the top of the plants. Try to look some guide that teach how to recognize which of immobile element is boring you now. Good luck and happy journey!

For me it look like a Cal/Mag problem. Witch and how much Nutrens u are giving ?

possiblly potassium deficiency - usually starts on the serated tips. if ppms of K around 180ish, probably fine unless something is out of balance and inhibiting uptake. if significantly lower, worth a bump and try to keep the levels of other things the same as best possible while you up the K.

Looking at the other pics in your diary, your plant has been displaying your classic "overwatered" look- which in hydro means your O2 levels aren't high enough or you're keeping your reservoir too full and the plant base is staying too wet. Assuming you're giving correct ratios, the chlorosis is likely attributed to pH.

Giveing this is a Hydo setup like DWC i'd say its an issue with micros. https://420life.com/wp-content/uploads/2021/10/Marijuana-Leaf-Deficiency-Chart-scaled.jpg I would look at you feed and ensure its getting all the things it needs, if this checks out then time to look at the PH and look at the roots. they smell or feel gross? is there a film in the water? should be one of these things. Keep water temps low to avoid gross stuff, 18c is a good point to try and hit.

Ninjabudsanswered grow question 15 minutes ago Hello there I would start with check the run off water ph level when you water (water that comes out the bottom the pot) If there's a.problem with the soil flush soil. If soil is acidic flush with regular tap if soil is alkaline then flush with water ph to 6 or slightly lower If you have no soil ph problem and you say you have been giving rhe bare minimum amount of nutrients then I would say you most likely need to up the nutrients make sure to have something rich in nitrogen Ya do as he says lmao. He knows what he is talking about flush your soil! ROFL!!!!

I Think you have a wrong pH in your medium. When i experienced on a hermie, i had this problem when feeding my plant 10 pH water. Also your plant looks exhausted, did you transplant her? Otherwise check temperature, light, RH and how wet the soil is, could be overwatered. Something is way off,
