Yellowing on the lower leaves 4th week into flower

[Sir3]

Hello,
At around the 4th week of flowering, the lower leaves started to yellow. Now, after aprox 6 days, it seems not to stop.
I use a TS1000. Nirvana Bubblelicious feminised. Biobizz soil and nutes. Also, the BioHeaven started to smell like it went bad. IDK if this is normal or not. The thing is, a month ago l broke my PH tester and in a rush, l bought a cheaper one. The yellow Chinese kind. What PH meter do you recommend?

Can anyone tell me if this is normal in any way? I checked and alot of people said that yellowing is normal. But this is new to me. I water around 5 liters every 6-7 days. 3 liters at first and the other 2 after 3-4 days. I water slow. .5-1L, wait 30 mins for the soil to bet wet and then another liter and after 30 minutes or so, the last liter. l wait for the pot to get really light. The leaves are bit droopy. But not too much.

The first 3 photos are from 6 days ago. Just before watering. And the last 3 are from today. The leaves have a little bit of nute burn, but just a little. I use a bit(3/4) under the recommended dosage.

Thank you very much

Calmag—5ml/gal every feeding and watering
temps—shoot for 84f while lights on

She is overwatered my friend.
Stop watering in-between watering.
Water with full strength nutrients.
Let dry for a few days, not completely in flower.
Then water until you get 10% runoff.
Then dry again.
Feed till 10% runoff.
Dry.
Water till runoff.
Keep alternating between feed & water.
But let dry between.
Do you have any b1, Superthrive or kelp products to help your roots.?

I use CalMag 4ml per liter on every watering. Because of the led panel.

I do not water in between feedings. I feed her every time. Are you saying that l should give her only water after giving her nutrients?

My temps are 23 C during the day and 18 Celsius during the night

 

[zigzagman1960]

My temps are 23 C during the day

ding ding ding ding ding

this is why your plants are all screwed up—this and not enough calmag

 

[Sir3]

Could be. I was hoping for higher temps. But this year is colder. Alot of rain. It is hard for me to raise the temp

 

[Sir3]

So the temps were pretty much OK. 26-29 during the day and 18-20 during the night. The PH was the problem. As l got my Bluetooth PH pen. And l was feeding them at 6.9 or so with the cheap ph pen. Never trust a cheap ph pen...
I attach pictures from today for comparison. The color is a healthier dark green. Leaves started to curl up in the last days. IDK why. Could be from the wind or too much water. As l watered every day or every other day to feed them. The same airflow is from the beginning. The ventilator is on the wind setting. All buds started to have brown pistils. Theoretically, l am 3 to 4 weeks away from cutting.

Well done pulling it back. My guess would've been pH or watering too much. I'd just do the watering in one sitting. I think that's what @Bill284 was suggesting. No need to go back and forth.

Also, the BioHeaven started to smell like it went bad.

I've not used it personally but heard it stinks anyway. It's a fish emulsion isn't it?

 

[Sir3]

@VetSmoke85ment that l watered every day. 2-300ml once every 5 minutes. For the water to have time to spread out

It wasn't smelling bad at the beginning. I guess it expired as l understand it is good around 6 months once you open the bottle
