I have two blue dream auto flowers in full flower. Both plants have yellowing leaves near the bottom, which I read is common. However this has slowly worked it’s way up the plant in the fan leaves. After reading it seems my PH is low. I am using Fox Farms Ocean Soil and people have mentioned needing to add PH and it was low when I tested.
The plant closes to the vent in the picture I think has about a week or two till harvest. The other is maybe three weeks or four. Not sure this is my first grow. The close up pic is of the older plant and was my attempt holding a damn magnifier and my cell phone.
I have a half gallon watering can and that seems to fully water my plant and give me run off. After watering the plant I test the PH and realize it is low. Do I refill my watering can at that moment with high PH and rewater? Or do I just plan to increase the PH in the water next watering? I am using cloth pots but I don’t want to over water and kill it.
Also there is not real instructions on how much PH to use per gallon. I bought the common orange/blue bottles off amazon. I have just been using a cap full per gallon.
Also my flowers are not turning blue. I assume this is a bunch of factors and mainly the fact that it is my first grow is a big one. The Buds are looking nice and healthy, one plant looks stringier than the other, but I think it is a week younger in growing. I think my biggest issue is the PH right now…
Are you adding calmag to every watering between feeding? The lighter green of the overall plant points towards nitrogen, a key nutrient in calmag supplements, deficiency, as well as the yellow fan leaves. The fan leaves yellowing is normal during flower, and the ones at the bottom can go bye bye. But calmag with every watering can show this
Also, there are many white hairs left on your girls. They may have a few more weeks. I’m just snapping that you had several questions. Let me get a support ticket and the real experts can go from there…

Welcome , you still have a few weeks to finish up. Yep I agree plant gets older you will have some yellowing leafs. But my frist thoughts plant looks hungry. What’s your PPM run off ?
Nice plant
Great tools. Cheaper pen but good calibration solutions. The holding solution rocks. Pen has a rubber cap for probe and sponge in lid to add holding solution. Also i am a firm believer in calmag and a heavy pk during flower. Could be mistaken but works great for me.
