Winter Grow

Fix by monitoring your PH going in and the runoff coming out, can do the same with the EC or also known as the nutrition solution strength. PH and EC go hand in hand when growing in soil less mediums. I would also recommend some Calcium and Magnesium when growing with coir as they rob the soil of it when they decompose slowly over time. I use tap water for all my growing needs and its fine, I grow in soil and PH it down to 6.5, your in soil less and may need a lower ph of aorund 5.8-6.2 Best Of Luck!

Check with city water supply website to see if chlorine or chloramine is used. Both are bad for our plants and microbials in the substrate. If chlorine, bubble it for 24hrs uncovered to gas it out. The ph will drop to 7-7.5 and stabilize. Much less PH down needed then and less chance for a drift. If they use chloramine, filtration is needed to get it out. Reverse osmosis works great, but it strips minerals that are beneficial as well. Most nute companies formulate on tap water with those trace elements. So if you go the RO route.. add the beneficials back prior to watering/feeding. Definitely want to flush your media with PH'd (and gassed) water. Waiting few days, then continue with nutes. 1/4 to 1/2 strength for autoflowers. Dont feed every watering. Best to start low and slowly ramp the PPM up if she shows no signs of nute burn. Wish you the best, happy growing 🤙

Hey Growmie, What you want to do as soon as possible, is flush your growing medium out with clean, pH-balanced water. When returning to regular feeding, use only 1/4 strength to avoid burning again.
