Leaves turning brown? Help

[wildwestsmoke]

I am using distilled water, with week one formula (Dyno gro AB) on the two bigger plants. They are now 14 days from sprouting.

I think they might be over watered. But someone told me it might be a calcium/magnesium deficiency.

The other plants in the red solo cups were planted two days ago and seem to be okay, I think.

First time grow.

Hi and welcome to 420mag. What soil are you using? What are your ph levels etc? Letting them dry out properly before watering is a solid way to avoid this, mine can sometimes go more than a week between feeds. It can be hard to Water then tho.

I am using 50/50 soil (3-5-3) and perlite. I did check and it is quite wet 2 inches down but it gets so dry on the surface of the dirt. Is it okay to have the top get dry. I have been watering once a day.

I water mine once a week. As they are in small pots give them a couple of days to dry out
