First grow went fine so I am a loss for words on this 2nd grow. I use soil and purely organic nutrients however this grow everything is going south and not sure what's going on. I use woven smart pots so I'm thinking they are under watered however someone else thinks they are over watered. Photo's are of different plants with each one having different issues from yellowing and dying leaves to yellowing and brownish spotting. Your help and thoughts are appreciated.
1. Well Water PH 6.3
2. Organic soil
3. Humidity 60%
4.Temp 75 F
5.Currently in vegetative state

Aqua Man thanks for the review, I am using a homemade soil mix I saw a professor describe on YouTube for growing cannabis. It's peat moss, perllite, blood meal, gypsum, worm castings, dolomite lime, this mixture worked just fine first grow. Only nutrients that do get added is the occasional worm casting tea and a little molasses. The plants are watered morning and evening for five minutes on a gravity fed drip system. Grow space is 8'Wx12'Lx8'H', completely sealed with Mylar, 4" Intake and 6" exhaust fans, portable ac unit stays on 75 degrees, dehumidifier stays on 65%, CO2 stays around 690 ppm. Currently have eight ladies in play however they are in dire need of help. I have two White rose 6000w LED lights and one Whiter rose 4000w LED all lights are at least 2 feet from the top of the plants. Last night I picked up one of the pots and it was really light so I'm thinking under watered my growing partner disagrees and thinks they are over watered. I'm thinking PH issue because the leaves that are turning yellow are mid range and lower except one plant who has all yellow leaves and I did not get a picture of this one but can if needed.

I'd say they are starving partially due to a lack of microbes in the soil to process nutrients into an available form, possible the soil density? And likely watering practices also.
I'm not an organic grower so I'm limited to help ya here.
Did you do a slurry test on your soil to ensure correct PH range?
How much and how often do you water? You should be saturating the soil then giving a dry cycle. This won't work if the soil is to dense and no matter what you do there will be issues.
If it were me I'd give it a shot of a balanced synthetic nutrient. And back the light way off because light drives the plant so if it's not getting enough nutrients it will only make things worse faster.

I just purchased a good soil PH meter will be checking this issue this weekend. I agree with your watering recommendation I just need to convince someone else.

Ok lots of posts on how to water plants. So I thought I would put together a thread on how different factors contribute to different results that ppl see. This will be a long read based on my personal knowledge, opinions, research and others work to consolidate information for our members. I'm...

@ComfortablyNumb recently did a great thread on a simple way to monitor and know when to water here also here.
The other day I had an idea and after testing, it works great. To know if you need to water, get yourself a soil meter. Poke or drill 4 holes in your pot 1/4 way up from the bottom spaced around the pot. Insert the meter probe into the hole and test for moisture. If its dry, then water SLOWLY...
