So, I have a question about an issue(s) I’ve been having in the FLOWER tent. This GSC just started Week 5, but this plant along with the last plant that I cut down, started really yellowing out in the lower branches. Leaves turn yellow, then eventually die off. The last plant, the stems became weak and fell over. I feel like it’s a deficiency, but as I’m relatively new to growing, can anyone help confirm? I have read that in flower, they have a higher demand for Cal-Mag?

Check the ph of your soil doing a slurry test. Might be your water causing a ph swing

@BigKarl I’ll do a test this evening. I do use RO water ph’d at 6-5-6.6. Had some issues doing that in hydro, until I read that hydro actually needs to be a little lower ph. All the plants in veg (except one) is looking great.

I don’t see any issues with calcium or magnesium. Your pH buffer is probably too high.

@jmystro is that purely in the soil? I added Lime for its calmag, but it’s supposed to be good for getting ph back into range. I’ll still do an Epsom salt foliar spray
