Leaves Dropping off and Yellow, Day 28 Bloom. both plants same symptom

If your looking or extra feed, something like Gaia Green or Dr.Eath would go well with your organic setup. They are broken down by the microbial life in the soil and they are organic as well. its dosing is aorund 4tablespoons per gallon of medium. If you need any other help reach out via DM "Direct Mailbox" its the little paper airplane logo/tab on the bottom right hand corner of your screen. Good Luck!

Hello, I am using ORGANIC Living Soil Concentrate 1LB mix with 10LBS of ROOTS ORIGINAL Potting Soil in 5 Gallon Grow Bag, Water only method, Temp inside is 86 and RH 60%, this is my first time , I understand I need to give nutrient to the plants, even the Living Soil advertise that just need to water )), Pls let me know What nutrient/food I should use in this phase and how much? Thanks guys really appreciate your feedback Thanks again

Your plant is dying off due to starvation. All plants growing in pots will eventually need extra feeding, especially in flower, no matter how good the soil was to start with. Plain water may work outdoors when growing directly in the ground where the plant can search out nutrition, but in pots, nutrients run out. This is why the leaves are dying and falling off. The plant is basically cannibalizing itself..........not a good situation if you are after prime buds.

My guess would be your soil has been depleted of its nutrients and you need to do a little top dressing. The other thing is your canopy is dense and this could be a natural defoliation. This can happen when the lower leaves do not get enough light so the plant will drop the old to focus on the new. But considering this will happen usually to only a few leaves here and there. I would say you need to add some more food. Happy Growing

This looks like an iron deficiency to me... yellowing starts in the middle of the leaf and spreads out towards the tips... Good luck!
