good deal thats what i was thinking it was? bottle has a light (1 tsp) and accelerated (2 tsp) feeding should i just use the light feeding of 1 tsp per gallon with the regular watering?
cal/mag is the major issue with coco. There are coco specific nutrients that deal with cal/mag issues. If your using ro water you probably need to supplement weather in soil or, coco with cal/mag. The yellowing of the lower leaves may be normal at your stage of flowering... Always best to give less every other watering than more and see how the plants adapt...
I use the 1TSP/gallon dose every water AND feeding. I've tried 2TSP/gallon every feeding only, but found I prefer a smaller dose more often. You're using RO water, and I know it's bee said a thousand times, but with RO water you need to add Ca and Mg, whether that be from molasses, epsom salts/egg shells, or cal mag.
good deal started adding the cal mag tonight. These lady's showed no signs of the def. during veg so I never thought to add it, but I'm assuming I should due to using coco and RO water?
Yeah, it's unfortunate, but you should. I did the same thing and didn't add anything to my RO water. It wasn't until I decided to try it I realized my plants were deficient, they were stubborn and didn't want to show it clearly.
