1st grow update: few are a bit behind & not too good

[Chumminsboy1]

I am about 8 weeks into veg, i am unsire of strains as they are bagseed. I currently have been getting some yellowing and leaf drop on a few plants.

Im running 2 tents

Main tent has a 600w led viparspectra plus a random off brand 300w led

2nd tent has a 300w viparspectra led

Using ffof soil in 5gallon smart pots.

Running ro water nd the ph ranges between 6.5-7.0 for the plants

Nutes used are ff grow big and cmag + from general organics

Im not sure if this is nute burn or a deficiency currently as its only really affecting my smaller plants?

Cannabis plants prefer a slightly acidic environment for its roots. Growers using soil as their medium should adjust their pH to a range of 6 to 6.8
