Deficiency showing after placing in flower, what could it be???? Help??

[Subzerho]

I have a couple plants that are showing a deficiency after being placed in flower. They were perfectly healthy no yellowing, nothing in grow. They were grown from seed if that matters. Where grown under a t8 light in red cups until they were 10inches or so tall. Issue only started after placing them in flower 3-4 days later.

Nutrients: 4 tsp ionic grow, 1stp Cali magic, 2 tsp of fish shit in a gal of water dispersed between all plants.

PH, 6.5- 6.6

Growing in fox farm ocean forest soil

Nute Lock out?

Hopefully it's minimal and they bounce back asap. Minus the few spots, they are good looking plants.

Are you currently using "ionic Grow" or "ionic Bloom" and what is the NPK of that fish shit you also mentioned?

That’s a nice chart @The Gram Reaper, where did you find that?

The one with plants on it I found on this site, the other one is older.

Did you change to a stronger light?

Just Google search marijuana deficiencies ( And click on show pictures). This is a popular chart that has been circulating for some time. It's hit-and-miss and I've heard a lot of old timers and seasoned growers that shoot that chart down saying don't trust it. So take that for what it is.

Taking pics daily helps so you can see how and where it started and how it progresses.

you need to get an E/C meter to test the strength of your nutrient solution.

If fish shit is fish emulsion, 2 tsp per gallon of fish emulsion along with the other nutrients you added will probably take your ppms off the chart especially if you happen to be using hard tap water.

The problem with that chart is that people use it, see symptoms of a deficiency, and add more of what they think the plant is deficient in. Too often the deficiency is caused by overfeeding causing some nutrients to be locked out. Trying to correct the deficiency by adding more only exacerbates the situation making things worse and having people chasing their tails. Often the best course of action is to stop feeding and give just plain water in soil or a very weak nutrient solution if growing hydro or coco.

That chart isn't the holy grail. It illustrates the symptoms of deficiencies or excesses but does not address the root cause which all too often is from overfeeding not from a lack of a specific nutrient being given to the plant.

so true.

To me, if its not a pH problem, its a deficiency / toxicity problem, but I don't ever label a problem being a deficiency / toxicity issue because both of those things happen solely because of a ratio problem, meaning, there may be to little or to much of something that needs to be in better balance with something else.

Thanks, I fully agree with what @xtsho said in the above post. I want to use if for reference to study these individually.

Good points.
