Diagnosis

So this plant had low run off ph and was looking locked out. I flushed it yesterday in the sink with 6.3 going in and 5.7 coming out. I flushed it until the run off was showing 6.15-6.20. and then put it back in the tent. This morning she is looks very deficient and im wondering if I can wait until the soil is dry again to water, or if the plant needs nutes ASAP. i am growing in coco and using grow big and big bloom in veg and now using big bloom and tiger bloom. I just dont dont know if there is enough residual nutrients in the soil now that its ph adjusted to hold the plant over till its regular watering time, or its starving to death.

Run off pH and EC means nothing, salt builds up in areas and gives u false readings

In Coco you water with 1/4 strength nutes daily, more in Flower

She looks hungry and unhappy

It's not a recommendation, it's how u grow in Coco

Coco is not dirt, it retains no nutrients in it, it's passive hydro, always needs nutes daily

Promix HP is pretty great. It self buffers it's pH

It's not a living soil so you need nutes

I switched from DWC to it with Mega Crop nutes, love it, just add the MC to tap water, and yer set
