Build difficulty not enough air maybe?

[Cherry__675]

I’m trying out growing for the first time it’s my second week this setup is from a book that I read. It uses irrigation sprayers and a water pump to recirculate the water like a low pressure aeroponic system. I’ve noticed that my plants have started acting strangely and am currently running under the assumption that it is due to insufficient aeration. Images of the plants + their roots are linked If anyone has any corrections in terms of diagnosis that would be greatly appreciated.

My current plan to help with aeration is to add a Venturi right after the pump to aerate the water being sprayed i also am most getting an air pump to see if that helps also.

If my conclusion/ plan for resolution is dumb please let me know I’d appreciate some help as this is my first time experimenting with hydroponics and I don’t know very much as of now. I can link a YouTube video with the same type of setup I found while researching that’s made for tomatoes and provide more images of the plants thanks everyone for reading the post i appreciate it thanks.

( not too sure how to tag sorry)

Welcome to Bud Builders. ^ This is what you want^.
Phosphoric acid.

shit i guess I should use something else then.

Local grow store probably has generic or decanted phosphoric acid for like $5-10 just shop around. Much better and will last you

Are you using calcium nitrate right now?

Calcium nitrate and magnesium sulfate

I don't think you need the Calcium nitrate right now, or atleast a very low ppm of it, like 10-50

Its a blend the cal nitrate is the only source of Ca and N in that mix. yeah lower dose

3rd day update bottom leaves are slightly yellow but everything else seems to be improving thanks everyone for their help I appreciate it

With my current mix my nutrient ratio is roughly 3-1-4 is that fine?

Yup that will work for now.i like a 2-1-3 bit higher P for Veg. 3-1-4 is for transition and the 2-1-4 after 3 weeks of flower to the end.

Thats a general plan i use

But that will work the entire grow and it can be slightly different depending how the genetics are.

Oh the strain is pink cookies would that affect what ratio I should use?

Couldn’t tell you never grown it and there are different phenotypes from seed. If you atay in those ratios the chances of seeing any issues is almost 0.
