When posting, include clear details about your strain, grow stage (veg/flower), medium (soil, coco, hydro), your nutrient brand and schedule, pH/EC readings, and any photos of symptoms so the community can accurately interpret your situation and offer tailored guidance. Start a thread with your nutrient question or chart to get specific advice and help others learn from your experience.
Root Protector from ILGM. I am having trouble with how to use this product. With the directions and previous posts on this site, I am still having trouble with whether or not to add solution of RP and water to DSW reservoirs with nutrients or to give RP solution to the plants, rinse it out, then place plants back in nutrient solution.
This is the only place I have found, after a long search, to say anything on this forum. Probably the wrong place too! What is the recommended mix ratio, for coconut water?

Hi there, bought the widows pack, currently on week 2 of grow after full germination. Working with a dwc setup, clay rocks for media, started seeds in rock wool. pH is balanced between 6.2 and 6.7. Not sure about ec. Nitrate levels were low added some high nitrogen fertilizer, ppm of nitrate is below 200 now. White widow and black widow are doing great for only being 2 weeks old, but chronic is not doing so hot, I will try to add pics. Grew fast at first then started yellowing and not growing much. Leaves are yellow but veins are green, thought it to be and iron or magnesium deficiency, added fox farm big bloom which is high in iron, also added general hydroponics calimagic to water supply. Been a few days since these additions and seeing no change in condition or increased growth. I have 2 chronic widow babies in one 5 gallon dwc bucket and one is way worst than the other, please help with advice or proper diagnosis of issue, thanks
