Most plants are looking healthy. Some of the plants in the middle of the room are getting some deficiencies, possibly a Calcium deficiency? I've tried a two day water only flush because I thought maybe there's nutrient lockout from the coco being dried on the outside after a late watering or two. I also checked the runoff on those certain plants and the PH does seem low.

Grow Questions
RemedyHarveststarted grow question 4 years ago
I have a deficiency, is it Calcium, nutrient lockout, or low PH? I did test the PH on some of the middle plants and they do seem a little low. It seems to be only happening to the plants in the middle of the room which is weird, plants on the outside seem healthy.

Also if you're using led lights and/or coco you're going to get some calcium defeciency at some point. The middle plant might get it first because she's receiving the highest light intensity. ๐ฑ๐

Plants in middle of room are likely recieving more light therefore process water and nutrients faster. I know in my experience when my substrate gets dryer as plants use what they need the ph starts dropping. You are probably crossing the line on lockout on certain nutrition. It's there just cant be absorbed. Fix the ph in soil and I would image you will be smooth sailing again. Good luck and happy growing ๐ฒ๐ฒ๐ฒ๐

Thanks guys for the input, I think you guys are both right in the sense that the middle plants are eating faster and it might have dried out a bit too much at some point and created some lockout. I am using coco so that seems like the most likely scenario. Thanks garden community!
