Need help crips dying

[Doctordre]

Crop is dying and i don’t know what the issue is I’m a noob newbie grower . I thought it was nitrogen deficiency so I gave it some advanced nutrients sensi grow but it’s still continuing to do the same thing.

using 600w hps lights
Biobizz lightmix and all mix mixed together all mix at bottom lightmix at top

it’s like 5-6 weeks into the grow

using tapwater after using advanced nutrients ph is at 6.0

I sometimes use house of gardens root excellurator at 1ml per litre

Do you have any pics?

How often are you watering? How much? And how often are you mixing nutes with water?

If you’re using liquid nutes, and watering habits aside, it all comes down to ppm/EC and pH. Aim for a pH of 6.5 for soil, and nutrients should be mixed to 500-600ppm (generally, for autos - less for seedlings and adjust as necessary as plants grow) excluding the ppm of your tap water. Soft tap water is better, so knowing the ppm of your tap water is also helpful. Also, don’t trust cheap pH meters (although cheap ppm meters are okay)’

The other factors with indoor grows are temperature and humidity. Check out vpdcharts to ensure adequate humidity and temps depending on the stage of growth.

And what about your light intensity? Have you looked into PPFD/DLI targets at all?
