i'm entering 3rd flowering week. I can see some of the old leaves at the bottom becoming yellow,and a few just pulled off easily. Is this normal? or is that a a problem coming from below?

Looks fine to me, some leaves will get nute burn or just die back when not getting enough light, its perfectly normal to have some leaf discoloration. Entering into week 4 flowering make sure the soil is dry before over watering or feeding, this is usually when people get over excited and kill the plant with too much TLC. Brown leaves never recover so snip off the brown bit and keep the rest of the leaf. Drooping leaves are the real red warning light but your plant looks great!

Yes it's normal in hydro to loose bottom leaves. Bit early but you have fairly tall plant.

Hmm if I had to guess I'd say the plant don't need those leaves anymore and she's using all the nutes from it until it will die off. You have lots of healthy green growth on top and artificial light don't produce UV light (Unless UV bulb) and therefore it can not penetrate through surfaces that easily. If some leaves are not getting enough light then the plant eats those leaves and focuses on the leaves that matter. Not 100% this is the case for you but she looks healthy so few bottom leaves is probably nothing!

bonjour, on dirait une carence de manganèse ce macronutriment immobile joue un rôle fondamental dans la physiologie du cannabis. Il aide à la photosynthèse, la respiration, l’assimilation de l’azote, l’élongation des cellules racinaires et protège les racines des mauvais microbes. Une carence en manganèse se fera connaître par des décolorations vert-clair près de la base des nouvelles croissances. Celle-ci s’étend jusqu’aux pointes et des taches marron commencent à émerger. Prévention • Un pH déséquilibré est souvent à la base d’une carence en manganèse. Mesurez fréquemment le pH de votre substrat et maintenez-le dans des valeurs optimales pour que la plante puisse accéder à ce minéral. • Mettez au point un compost riche en manganèse par l’ajout d’ananas, de tomates, de cranberries et de carotte. Solutions • Rincer votre contenant. • Tailler toute croissance affectée qui ne s’en remet pas. • Asperger la canopée à l’aide d’un spray foliaire d’algue. J'espère que cela va t'aider bonne culture
