New to growing

So I am new to growing cannabis, how does this look for starter?
I try to do my research to try and correct any problems.
I use RO water ph'd at 6.8
Set up is a 2 feet by 4 feet grow tent( just a cheapie one)
Lights: Viparspectra LED 450watts and recently added 2 CFLS to supplement the dark areas of the tent( I believe a 3000k light)
Currently week 5 into flower, but not all the plants I have are the same age, experimenting on how flicking 12/12 light has on different ages of plants.
Strain: unknown bagseeds
Tried various training on the plants: supercropping, low-stress train and topping
Pictures:

Was wondering if its normal for like the bottom half of the plants to really be yellowing out and falling off?
My temps are 80-85 degrees Fahrenheit and humidity ranges from 40-55
Also I noticed that the plant to the right of my grow tent; the soil does not dry up anymore like it used to every other day. It takes like 4 days for it to dry up now

They are good

Okay so one of my plants in flower is having issues, I am not seeing any growth in bud size. The soil is not drying up. Is it a possible lock out? I have never flushed the plant in its life. The soil is generic miracle grow from home depot. So when I feed, I only use like 200-250 PPM of Dyna Grow Bloom nute. I flushed it 2 days ago and it's still not showing any sign of improvement, should I continue to flush it?

Have u pic of the plant that's not well and also where did ya get ya lights from as if it's a cheap Chinese thing may not be what it says on the box when I started I used cfls and was same thing buds wasn't getting any bigger I'm now on my 3rd run with hps light far better bud size that's just one of the trays of last run just shy of six Oz of two plants

Wudnt flush either

......

Sorry for the late post, I'll get a pic as soon as I can. The light im using is a 450W Viparspectra LED from Amazon. and I am supplementing the darkareas in my grow tent with a 3000ish K cfl light.

My issue right now is one of my plants stop growing, I noticed that when the soil did not want to dry up in its usual time, 2 days. I let my soil dry up in between feedings and its threw me off because it seems to not dry up anymore.
I think it can be a nute lockout. The plant is week 6 into flower. What do you guys think?

The rest of my flowering plants that I water are drying out except that one im having issues with

One hyphenated word. Miracle-Grow

And don't pH RO water. RO and distilled water have no real pH of their own as they have nothing in them to give them a pH. Mix your nutes up THEN check your pH. If they are decent nutes they should be good to go.

Sounds like your plant has root rot and the plant is just getting enough water to survive atm.

Well said.

Man I think it is root rot, I'm not quite sure how to fix it, idk if its possible. Yes it is Miracle-Gro soil. Big mistake, but in the beginning I had no knowledge of how to even grow.
For now I just defoliate the problem plant, I'm hoping that doing so will make the plant use less energy to compensate for the root rot. I'm estimating I will be harvesting it in 3-4 weeks. Hopefully the plant will survive.
Thank you for the insight

On a side note; I did try to flush it with FoxFarm Sledgehammer, I pH the sledgehammer mix to 7.0, but when I checked the runoff, it was 4.3. I think the soil could be acidic. Maybe due to the root rot?

Your situation sounds very complicated. I'm a new grower, and I'm hoping that as long as my seeds grow taproots and I plant them in hydroton rocks with my light on, and put the necessary nutrients into the water of my hydro system, I should be good to go.

Ive never grown but think i can help... whike doing my research i read that RO water absorbs/nutralises the calcium from soil/feed and makes it unusable for the plant so the plant gets no calcium. It also advised to only use RO if you know how to add your own calcium.
Hope that helps

The plants are just barely going, will be harvested soon. The plant with the problems hermied a bit. Found a few pollen sacks which I took off.
I made sure the tent has no light leaks. I believe the hermie came from the stress the plant had. F***ing miracle-gro soil
Other than that, the plants have beautiful trichomes, some are turning cloudy. But I am looking for that amber trichome for the couchlock high
Wish I can post pictures, but my camera is broken at the moment

**Bud size isn't all that, but I think it's decent for a new grower, about the size of a bic lighter. I am going on week 8 into flower

Here is a little update, I will be harvesting that trouble plant in a couple of days. I been flushing it but the miracle gro soil is so shitty, the slow release is not allowing me to yellow out on the fan leaves. The trouble some plant is the one to the right on the full picture

The 2 plants in the middle are experiments, they are 2 liter bottles in a hempy style. One is a clone of the plant to the left and one is a bag seed.
Im surprised with this "passive hydroponic" hempy style actually caught up to my oldest plant in flower(left one). Meaning, I flowered the 2 experiments like 5 weeks after I flowered my left plant and it caught up fast.
