BobGoosestarted grow question 3 years ago
Does anyone recommend a Reverse Osmosis filter?
What are the advantages and disadvantages?
Currently my tap water is 0.8/0.9 EC so not sure what I'm feeding my plants
Any advice is greatly appreciated
Thanks

That is quite a high EC for tap water so can see your troubles. Hopefully it is just an excess of calcium in the water but you never know. I would try any 5 stage on amazon you can find... Usually they give a gallons/day rating or litre/hour rating and you choose what you need by how much water you use. Sometimes the small units used for fridges are good enough for a small grow. Bare in mind if using RO water you will have to add back CalMag for your plants but at least you know thats all thats in it. I hope this helps, good luck

As @braverheartgenetics, and @papa_t, said. With that high a Ec straight from the tap it's probably the best option. Make sure your nutes are for soft water and not hard water when you use Ro water.

Don’t try to PH straight RO or test your RO water with a digital pen.
The pen will aimlessly drift and not give you a reading as there aren’t enough particles in the water for the pen to electrify and get a reading.
If you’ve tested straight RO with your digital PH meter please do re calibrate your PH digital meter.
Cheers 🤙

We have decalcification machine. Should I add Calmag right from the start? How much? (Autoflower in mostly Biobizz Allmix)We have a decalcification machine (natrium based), so I have low magnesium/calcium. People say my soil is low in cal/mag. Should I add Biobizz Calmag on my first watering?(50% of recommendation for autos?) This one looks already droopy, doesn't it? Think I need to water soon.

Feeding After Trauma QuestionI will feed super lightly tomorrow on August 7, but want to what other growers think.
Kaboom toppled over on August 3. I refrained from feeding to allow her time to stabilize and have only watered once since the fall. In your grower opinion, was waiting to feed necessary? thx 😊3 months ago

expert opinion asked ? Maturity in day 49 flower from 60-65 (according to breeder)Maturity in day 49 flower from 60-65 (according to breeder)
I'm not sure about the degree of ripeness.
I used Co2 for a few weeks (1000ppm), the grower says ~60-70 days of flowering, so I would be missing 10-20 days, but they look quite ripe ?
What should I do
Thank you

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.Setup. Strain - Autoflowering
