Hi there folks, these plants are about 4 or 5 weeks into flowering. They live in 5 gal fabric pots, ffof ffhf is the soil mix I’m using. I’m running GH trio, with terpenator and bestie bloom, cal mag, and some Epsom salts lately because of this persistent mag deficiency. Ph is always between 6.2-6.7, just need some help. Not sure about the yellowing and purple coloration? Any suggestions much appreciated.

You're adding a bunch of stuff you do not need. Next grow, follow the chart. If a supplement isn't on the chart. Don't add it. Use the basic 3 part with Cali-Magic. Nothing else.

Plus the notorious Fox Farm stuff. I've never read about so many problems with people using Fox Farm. I've never used it, so I can't say more. But the weed problem section here is full of Fox Farm grows with problems.

The PH target should hover tight to 6.0ph. Going as low as 5.7 up to a max of 6.3.

I've never seen or had a flush work. Any PH change has to be slow.

Example, if your ph is 6.7. Lower that figure to 6.5, 6.2, 6.0. Don't rush the ph by going from 6.7 to 6.0. Thats too fast.

Download the GH chart. Feed it exactly like the chart says. Keep the dose within the PPM listed on the chart. To include the listed Cal-Mag dose. Since Cal-Mag isn't a GH product. I'd go with 3ml Cal-Mag to a gallon. If you get the Cali-Magic. Then its 2.5ml a gallon.

My opinion is Fox farm soil is good enough to grow...but you need to amend more into it to make it more complete. I amended mine with azomite, bio-live, more perlite and Diatomaceous earth. Seems to me that the magnesium runs out quickly in that soil.

I'd rinse (flush) your soil and then go to half strength base nutes without all the extras (terpenator, bestie bloom, cal mag, epsom salts).
If I learned nothing else growing weed I learned that half strength nutes from beginning to end is the best practice.
All these gimmicky extras do nothing but take your money and occasionally, or more than occasionally, poison your plants.
I wouldn't worry too much about PH in soil. That's me. It works for me. You'll see other opinions.
But I've never had an issue and I only grow in soil, indoors and out.

And I love Recharge. Totally recommend for bagged soil grows.

Build a soil is what I’m doing my next grow. Light mix for seedlings. Then transplant to 3.0 mix. After that I’ll just be amending and reusing.
I gave up on the soil like mixes. Like promix. Went with coco and I've never had it so easy. I stabilize the pots three days before they go into the grow room.

Plus it gets better after the first grow. Much more stable. My current plants are growing in pre-used coco. Second time, they got a Cal-Mag bath for two days(15ml per gallon of tap water). No flush afterwards.

Zero ph problems. No Cal-Mag problems either.

Loooooove Recharge. Also, I just ordered some Foop to bring it home in flower.

my soil is stacked with beneficials. Great white, bio-live fert, recharge and then the foop. Lol. Trying to get those legendary terpenes.

How cold? Are you measuring leaf surface temperature when the temps drop?
Originally when I was trying to figure out my environment, temps would get into the 40’s in the tent. Idk about leaf surface temps, but I have the thermometer down near the pot. I’ve added a seedling warming mat and kept my heater on longer and that seems to have helped for now. Temps stay from 75-80 with RH about 30-35.

An Infrared Thermometer is a handy thing to have. The leaf surface should measure from 72° to 78°. Leaf surface won't be the same as the air temps.

Once you know the LST. Then you can use a VPD chart to fine tune the RH%
