Mornin all, got an issue arising with the 3 oldest plants. I'd been using bio canna veg and flower nute no issue, stopped with veg and added bio boost even though I'd been warned autos don't really like boosters, silly boy lol, so I'm guessing that the problem is boost as it's only on the 3 I gave the boost to. I had this same problem last grow but put it down to light burn as it happened after I swapped the cfl for led and the other plant I gave boost to last grow didn't have any problems.
Moved the light up to 20 in just in case but the other 3 plants are the same height and not affected, also not had any boost. Yesterday I flushed the 3 affected with 30 ltr water each to be on the safe side.
