How does my grow look?

Thoughts on my babies? Nute deficiency? Light burn? Over watering? pH off? What are your reflections on how they are looking now?

Summary:
I am watering only a small measured amount now, to avoid over watering, and once per 2-3 days.

1/3 EWC/Vermic/Peat was causing new seedlings to yellow unfortunately.

So I decided this mix failed and transplanted to starter soil mix in a slightly bigger pot, I hope they have a smooth recovery.

I was not sure if some plants also got light burned as tips were yellow and thin. Although I turned on another light for bigger plants, I moved it higher and turned down dimmer to half power (240 watt QB).

It has been a very difficult start to my first indoor soil grow. With a lot of trial and error, newb mistakes and attempts at fine tuning...

I've been doing my best to carefully watch the substrate pH and keep at 6.5.

I'm trying a few starter mixes. Some of the mixes have pertlite and other do not but I think they are all well aerated.

Yes I'm trying to find the balance in watering. I know it is delicate, not too much or too little.

1. Would you say its a good idea to bring moisture up to 75% ("saturating") then down to 25% ("dry")?

2. What do you guys think was causing the yellowing?

3. In the image attached, you can see the RH and Temp for a 1 day period. As you can see, there is some heavy fluctuation of the RH (due to aircon kicking in which triggers the humidifier). Could this be causing yellowing and the stress we are seeing?

My problems always seem to come from overwatering. You gotta wait until the pots are light. Maybe fill an unused container with your potting mix to use as a comparison. In my limited experience it's better to let them dry out a day too long rather than water them a day too soon.

I don't think swinging from 75% to 25% sounds like a good idea. Seems like a stable environment would be best. The yellowing could be a nute issue or a ph issue, both of which could be caused by overwatering. Are you feeding them anything other than water?

I had a thread a week or so ago about worrying about the rh in my tent. I carried on about VPD charts, started running two humidifiers to get the rh over 60%. Ended up causing myself more stress and problems. The general consensus in that thread was that I was just overwatering.
 
Overwatering takes a while to correct since a tiny plant has so few roots. The seed starter mix is fine. Like the other fellow said, an empty container full of dry mix is a great thing to use for comparison until you get used to watering.
 
Thanks guys. A stable environment is or is not the best? Many experts have said that cannabis likes a cycle of dry and wet.

At the same time, I thought it prefers a specific ideal range. According to a high times article I just googled, it said "At saturation most well draining soils should hold around 45 – 50% water by volume."

1. I still wonder: at what level should it dry out to before watering again? Perhaps 15-20%?


2. So it appears that over/under watering may have been causing the yellowing?

3. In the image attached, you can see the RH and Temp for a 1 day period. Could fluctuation in that be causing yellowing and the stress we are seeing?
 
When the soil dries out, the roots grow to find more moisture. When its constantly wet, the roots dont need encouragment to grow. This is the delicate balance pot growers in soil must manage.
 
1. Let it dry out all the way. The pot should feel just like it did when you first filled it up with dirt.

2. Yep, overwatering can definitely cause a whole range of problems, including yellowing.

3. Can fluctuations like that cause the stress you're seeing? I guess it's possible, but it's far more likely that it's just overwatering. I would focus on getting that sorted before making any other adjustments.

Are you using any beneficial microbes (Great White, Recharge, etc)? I am for the first time this run and the roots seem to love it. It's always good to keep the roots happy. I'm not suggesting that is the problem here, but it seems to be working well for me.
 
I'd say 70% of the problems I've had growing, come from overwatering. It also attracts bugs and lets the flies thrive. Keeping the top layer dry kills the environment they lay their eggs in.
 
Watching.

hello, new grower here too. Popped 2 autos.

not as far along as you but would like to see how you handled issue just in case:)

thank you
 
Yes I am using some Myco+ when transplanting up.

Okay I will be careful not to over-water. I am surprised to hear that it should by dried completely like 0% moisture but its a good tip that roots need a lack of moisture to grow, so they go in search of it.
