My WWidow plant's buds are not really fattening like i would like. What could be the issue? Too much nitrates? should i stop giving nutes at all? maybe its the mites making the plant suffer? Thank you for your kind answers
Week 9
Buds. Not fattening

Hello ! That dark green colour is a sign of nitrogen excess on a late stage. You don't check your EC/Ppm level so it will be hard to really know how much you nutrients you gave her since the start but I can see the excess settled between week 3 & 4 and you were using a 8-5-5 npk nutrients , if you did not respect the cycle water / nutrients / water / nutrients etc then it could be the cause of your issue , in the other hand if you did respect that chart then maybe you should go with a water / water / nutrient / water / water etc .. schedule . When you started your 10-16-25 NPK nutrient then you plant should have changed a bit her colour so your plants are under nitrogene toxicity and it is why their are slowly flowering. I guess that your flush did not wash enough nutrients away , maybe just wash the salt buildup but still remain plenty of N in your soil , so if your molasse is just a PK nutrient then use it until the colour become a bit more pale , if not then maybe another flush will be necessary to "reboot" your soil and then restart with your 10-16-25 nutrient. I hope it will help you and I encourage you to get an ec/ppm pen as soon as possible to avoid any nutrients excess/deficiency :grin::+1:

Hi @NewbieMJ00! From the color of your plants I can tell you overfed during the previous weeks. Too much nutrients (especially Nitrogen) during the veg stage can definitely lead to this kind of slow bud development. But this is not the only issue. Light is one of the most essential elements for your plants, some genetics need more lighting power than others, my guess is that your WW is suffering from lack of light combined with a previous nutrient excess. In fact, light helps the plants to convert nutrients into energy, so if you did not gave your WW enough light, she was not able to handle the N toxicity. As a result, she's now building its bud very slowly and those buds might end airy. Next time, grab an EC/PPM-meter, this will help you to ensure you're giving just the right amount of nutrients. See those purple stalks? That's a Phosporous deficiency coming on. Your medium is so flooded with Nitrogen that roots cannot handle Phosphorous intake anymore. As a solution I would flush the medium for 4-8 days before giving it a good meal with a reasonable amount of P+K. Hope this will help, keep us up-to-date and happy growing :facepunch:
