thank you I will get a digital meter and try it thank you after checking what do I do I am sorry for the dumb questions but this is a first time for me need the help

**ONLY DUMB QUESTION ** is the one you don’t ask.

suggest you buy a PH n PPM Meter set…$20 online. Critical.

If you use prefertilized media…good chance it will burn the plants.

Welcome to ILGM, @moonman13!

thanks nice group of helpful people I need you all

is it ok to flush with water whit a ph of about 7

Are u in soil or coco? And flushing for nute lockout?

In soil ud prefer 6.3-6.8. Unless ur last runoff was low, then to raise it u go in higher.

In soilless mediums (hydro/coco) u wanna stay around 5.8-6.2. Although some do like it a bit higher and some a bit lower (few tho)

What dose this look like


soil is what she is ini think I got the nute to hi I was going to try flushing to see if it helps

I just uploaded a pic of her and thank you for your help

I agree, looks like it could be a little bit overfed. The drying leaves on the bottom, is it just a few? She looks pretty bushy, maybe could stand to lose a few leaves. It will help with airflow. Overall, she looks pretty good to me! Stay on top of the pH and PPM of what’s going in and coming out, and you’re golden. :v:

They’re probably nothing to be too worried about then. Maybe they got splashed when feeding.
