Problem with young plants, digestion and bending

Hi everyone, I am very happy that there is a place on the internet where I can describe my problem :slight_smile:

Some of my plants have problems, I am not very experienced, so I ask for advice.

I put photos of those who have something wrong and sister who is growing perfectly.
The last picture is healthy, like most in the room, but these few pieces worry me…

The plants have 16 days, I watered twice with Micro, Bloom, Grow, Voodoo Juice and B-52 from AN, but when I notice these changes I water with water only.

I will also add that my humidifier is a sprinkler and tiny water particles spray the room, but there are no drops on plants or wet soil.

I will also add that my humidifier is a sprinkler and tiny water particles spray the room, but there are no drops on the leaves and does it wet the soil.

Can you upload pictures? It will give us a better idea of what the plants look like and what is going on

Dont use bloom nutrients in veg. Best for you to google a feeding schedule for the product line you use. Should say when to use what products in the lineup. Also try using half or less of the recommended dose and see how it works out.
I’m a hydro grower so more experienced soil growers will chime in as well.
Best of luck with the grow and welcome to the forums

I use fertilizers according to the manufacturer’s instructions. On the Advencedt Nutrients website recommend using these five fertilizers during the growth phase.

@Szmulu did it correctly. Grow-Micro-Bloom is a 3-part product which is used throughout the grow, but uses different ratios during different stages.

@Szmulu I couldn’t find out any information about your soil, other than it “gives your plants a decent source of nutrients to begin with.” Some websites said it gives a week worth of nutrients, others said up to 3 weeks. Hopefully someone else here is familiar with this soil and can give you some tips. Until then, I would probably back off a little bit on the nutrients if I were you.
Other than that, a few notes…
It is normal for new growth to be light green in color.
It’s a little early to tell, but it appears you might be in the early stages of magnesium deficiency.
Some of your plants (the ones with really dark green leaves) appear to be getting too much nitrogen.
And lastly, a tip. Don’t water right next to the stem of your plant during the vegetative stage. Water in an imaginary circle created by the reach of your leaves. This will cause the roots to reach out for the water, and your plant will get wider at the same time. Like this:

I did mention experienced growers would chime in. Sorry for trying.
Maybe dont nuke it would have been a better statement.

And be sure not to overwater it. Causes twisted freaked out drowning leaves if overwatered.

Check your runoff pH. Your soil comes as 5.7, which is way too low for a cannabis soil grow. If you are adding nutes then you are driving the pH even lower. The listed EC for the soil is 1.5, which is 750 PPM. I would recommend checking your runoff PPM too since they look a little nute burned. 750 PPM is plenty for plants that age and small plants won’t eat it very fast.

Thank you very much for such quick answers. I measured the pH and EC of the leaking water and had 5.8pH and 1.9EC. I decided to make a flush. I’ll let you know if it helped.

Yep, that low pH is likely causing deficiencies of any/all of the following: Phosphorus, Calcium, Magnesium, Molybdenum. You should adjust the pH of your water up to counteract it, and check your runoff pH every time until you get a handle on things.
The pH range for growing in soil is 6.2 to 6.8, with 6.5 being the sweet spot.
Here is a soil chart that shows you what can be locked out from the plant when you stray outside that range:
