Help ! My leaves are curling !

Hey everyone !

A couple days ago I started to noticethat my GSA plant had one of the top leaves starting to twist over. Now I have the other ones on the top of the GSC are starting to do the same and they are starting to turn yellowish on the edge. It's really the top leaves right now . My Soul Assassin on the right started boating today too but in the middle on 2 leaves. Also there are little brown spots forming on both.

The GSC is about a 6 weeks in and the SA OG is 3 weeks from clones (my cat ate one and had to start over)

I have a Hydro system with a reading of 700 ppm and the PH is at a 6.0 . I'm using Age Old grow nutrients and 5k CFL bulbs about 3 fists away.

I also put the steaks in about a week ago . Maybe it shocked the roots ?

I haven't flushed in 3 weeks. Bactria , or neutrient salt build up?

Can someone please help me understand what might be going on with these plants?

I attached some photos for you guys to see .

Thanks for you're input!

I'd say your nutes are off. Cal/mag, ratios, last time you changed reservoir?

Hi thanks for your response . I just cleaned it out today and I'm flushing it without neutrients for the next day . I saw that the Age Old has manganese. But no magnesium . Is that a problem? I plan on going into the blooming phase after the flush

T-Bone or Rib-eye? My plants love the Rib-eye but the T-Bone steaks does nothing for my plants.

You need calcium and magnesium. Yeah, it is a problem if you don't have them in your nutes or water.

Yeah and also depending on reservoir size you should be swapping it out a lot more. But your nutrients say not to use it alone

Post a root pic and calibrate your pH meter.

I calibrated my TDS today . And omg ur right ! It does say to use it with another fertilizer! That hydro shop gave me bad advice ... Thank you!
