Hi all. Just a quick one.
Do I need to use calmag on every watering using a sf4000. It's my first time using a led. Thanks for any advice. 👍🏻👍🏻

Depends If coco is present in your substrate. If so then I would use it more often then not coco absorbs cal mag.

Calcium, lock out?Hello, it looks like calcium, P, or K issues. Maybe pH lock out. I flushed last week and followed with nutes. Likely last nutes this week followed by a week or two of flushing before harvest. Please look at leaves and let me know what I should do as I end off this plant.

Yesterday evening I've sprayed a bit the plants with water. This morning they had nothing, they appeared in the late afternoon.

Liquid OxygenWould you all use this in your water when trying to give oxygen to the roots? I’m noticing some really dense, not drying up that quickly soil so it’s making me think that they can’t breath. I don’t know, just making sure every part of the plant is happy & healthy.

Rust-colored margins and dots. I would like to go back to fertilizing but I am afraid that it is an excess of potassiumOutdoor in the vegetative phase, southern climate. Soil is Biobizz light mix. So far I have only fertilized 2 times with the tripack ph perfect Advanced Nutrients. These rust-colored burns are present on almost all older leaves. Enlighten me please 🙏

PH Fluctuation Early Signs?I am worried that I either have early signs of PH fluctuations outside of 6.0-7.0 range or early signs of a calcium deficiency.
As you can hopefully see in the picture the tips of the first set of true leave seem to have little spots of discolouration.
Any help is appreciated😊

Low PH runoff, dealing with deficiency due to low soil PH. Added lime and PH went from 5.4 to 5.0 after watering. How to raise it safely and quickly?I have been dealing with a nutrient deficiency so added nutrients.It looked ok but then got a bit worse and I took some runoff readings which were 5.4 and then 5.0 the next week after adding lime to raise soil PH. How can I best raise the soil Ph being that I added lime already.

WaterIs it bad to make my water ahead of time ? I mixed my nutrients (big bud, formulex, bud candy & molasses) in with the water & have let it sit out for over a day. I heard letting it sit out gets the chlorine out (I put a towel over it though so my cat/other stuff would get in it)

Why isn't it going away?It might be a potassium deficiency and I believe it was so as i was running out of nutrients and i had to lower the nutrient dose i was giving by hand. On the 22nd, i added the nutrients to my AutoPot reservoir so that i no longer had to hand water them and it still has this. SOS
