Plants turned sick in a week?

[Praying for better times]

Plants looked like this a week ago, first pic.
now just a week later they are looking like the second two pics. Using fox farms soil Trio with added potassium, in pro mix HP. Any help greatly appreciated

They look nitrogen starved now.

What are you feeding 6-4-4?

looks like a ph problem multiple problems, too much potassium ( i think )

Came here to say that. FoxFarm trio is already hot. Back it all off a bit and don't feed extra potassium maybe until flower..

i see a lot of bad plants in that fox farm , pots should be lined/layered

It has to be a over fert issue in my opinion. Because you went from dark green healthy growth to yellow so they must have maxed out and locked out from high salt maybe fuck same shit as me brother

A lesser known but equally important interaction is the one shown by the Mulder’s Chart (Figure 2). The Mulder’s chart represents the interaction between 11 of the essential plant elements. Some interactions are positive (synergistic) and others are negative (antagonistic). A synergistic relationship is one where the elements involved help each other by aiding uptake or utilization. In contrast, an antagonistic relationship means the elements hinder each other in uptake or utilization. For example, adequate potassium aids in use of iron and manganese, but if it is too high it will hinder (antagonizes) utilization of magnesium, boron, nitrogen, phosphorous and calcium. An antagonized element may be present in adequate levels, but there is so much potassium present the plant doesn’t have access to it. Elements that act as antagonists can do so in a couple ways. If calcium is in excess it can simply out-compete other elements such as potassium and magnesium for uptake sites on the roots, or it can change soil chemistry by elevating pH to the point iron and boron become unavailable.

Do a search (forum or general web) for Mulder's Chart. Print it out, along with the many available nutrient toxicity/deficiency texts/pictorials. Refer to both as needed - and impress your friends & family with your newly found knowledge .

Using fox farms soil trio, adding 1/16 tsp potassium to a gallon of water.

I have not changed them to bloom yet still in veg

You may want to remove all the dead leaves, and transplant into a bigger pot. Change the soil. What are you doing to keep your soil ph within range of 6.0 to 6.8.. dolomite lime , oyster shell powder? Ph up down?

 

[Sulbones69]

Do you wait for the pot to dry out before watering. Ik Tiger bloom lowers your ph.

I'm sure it's a fert problem , when younger they were sickly I was told then add potassium , they turned beautiful like in the first pic, I know fox farms is hot, I've used it for years and it's constantly burning the tips. Would be open to a better fert , most people are hydro now not much soil info.

What size pots & how old or big are those plants ? Looks like they could be root bound & not taking up the nutes correctly.
