Water more....perform a heavy flush of the substrate to bring the PPM down. Only way to help your high levels. Good luck and happy growing

Maple tree water as fertilizer?
Has anyone ever used maple water from a maple tree as fertilizer for there plants? I traded my neighbor a nug for a gallon of sap water and lightly misted the soil top on my seedlings. FIY raw sap water is very healthy for humans it’s full of manganese + probiotics.

Feeding right after repotting (coco coir).
After repotting an auto flowering plant I get runoff EC of 800, while feeding water has EC 1200. I guess EC gets diluted (biggest part of coco coir is new). Should I increase EC of the feeding water? I see slower growth but it may as well be due to stress of repotting.

Watering in Super CoCo
Hey there fellow growers! So I’ve been trying to figure out the best watering schedule and volume 🧐I’ve been told to always water with runoff, go by weight, top inch dry, etc. I guess my main question is runoff necessary when watering in Super CoCo? All advice appreciated!🌱

Nutrient burn/deficiencies/feeding
Having difficulties with a few of my plants, I didn’t add any nutrients until they were close to 30 days old. And then only cal-mag at what I thought were low doses. One of mine has lost almost all leaves. What would you guys recommend moving forward? I have almost all fox farms

Potential overfeeding
Hi, this is my first grow and I'm running synthetic nutes in a biobizz light mix soil. After today's feeding, the run off came with 4000ppm when I usually get 2500-3000. I hear that you're supposed to get that when using part organic soil but 4000 seems problematic. Any ideas?

Nitro toxicity and calcium deficiency. Should I flush?
Little pas halfway through flower and appears I have nitro toxicity, could this be a cause of my calcium deficiency I have been dealing with? Should I flush it or would that continue the degradation of the calcium? The spotting has gotten worse then my pictures

DWC PPM First feed
I used rainwater with ppm of 15-18 and mixed 8 gallons with 18 ml of GHE Bloom, Gro and Micro with 4 ml of CalMag. Both buckets have new PPM of 350-390. Is that too aggressive for day 9? Or can I push more? New to DWC and growing and hoping for some applied knowledge. Thanks

When using ffof soil that says it has a pH of 6.3-6.8 is it still necessary to pH my water when using nutrients?
This may be a stupid question but w ffof it says the soil is already pH 6.3-6.8 so my question is do I still need to pH my water when using or not using nutrients or is there no need to because the soil is already the correct pH?

When you buy spring water, how can the company say it's a certain pH if temperature affects this ? I'm struggling to understand how temperature affects water so much. Does the heat make ph rise or fall ?
