Week 3 I need some help to indicate to issue

Hi happy growing to everyone,

This my first grow ever. We are at day 23. soil is plagron light mix. I started feed them 13 days ago with Advanced Nutrients. I have two MarsHydro tsw2000. Usually 25-27 Celcius and 40-55 RH at light. I have 20/4 light cycle.

I could not indicate the issue with my plants. according some research I thought it can be Cal/Mag deficiency or overfeeding with fertilizer. So I have feed them today with tap water with 6.22 pH and no nutrients. My pH arranges always 6.2-6.4

Thanks for any further advice.

I would put them at 65cm until flowering

That’s the height I run the ts1000 if you are running full power. Hope your running like 50%

nope. it is their full potential 100% @Autodoctor

Yeah u have it set at the flowering height so I would deff raise. They should have a chart but needs to be like 55-65cm during veg if not just killing them

thanks man

Autodoc nailed it
