PH and temp
Dean1started grow question 4 years ago
Does the temperature of the feed alter the ph. I made some feed a week ago ph 5.9 but had to turn radiator off in the shed because snow kept melting so feed is now 10c in stead of previous 18c but I checked ph the other day and it had gone up to 9.3 can I put feed in tent 4 heat?

Temps do affect pH but it shouldn't be that much. Water at 7 pH will have a pH of 6.14 at boiling temperatures. I would take a small sample into a warmer area and retest the pH. Most meters compensate for temp as well, so if it gives you a temperature, it probably automatically compensates.
Shake up your solution very well before taking a sample. Low temps could have caused some kind of separation within the solution.

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
