1st grow/scrog

Hello all - Plants are about 6 weeks old. Lemon kush, liberty haze, white diesel and sweet tooth. Been having a few issues lately but they are still coming along nicely. Friend and I just installed a screen to scrog our 4 plants. Total cost for the screen was maybe $15. Here's a pic of our set up. Really hoping the screen fills out in the next 2 weeks before switching to flower. Any input or tips would be great.

Back off on the nutes.

Are those pots lifted off the ground. If not, it will be a bitch to test run off and too flush if you need to. If say you prob need a flush looking at the nute burn.

Check out my signature hopefully there's a pic how I raise mine up to flush and check run off- just to give you an idea.

Have you topped it?

Thanks @kiwipaulie, I don't think it's nute burn as they've only been fed 3 times at half strength in their 6 weeks. Did a flush about a week ago and fed nutes 2 nights ago. They were very deficient before the flush and figured there was a lockout so flushed em, waited and fed again. New growth is looking much healthier.

Great advice on the runoff bit. They are just set in a tray at this point making that runoff test almost impossible. I'll have a look for your pic to get an idea.

3/4 have been topped including the sweet tooth that mutated and topped itself from the beginning.

I'm still on my first grow to so I don't have much to offer. I wanted to scrog my first grow as well but figured I'd wait till at least my second grow so I can get most of the basics down first. So props for jumping right in. don't know how hard it would be to scrog four different strains under the same net.

Is it a good idea to remove a few fan leaves to expose some of the bud sites to more light or is that not advisable?
