Hello all. First time grower/poster. I have a 4x5 tent with 6 plants in it. I have 4 different strains: Sour D, Straw cough, a Jack Herer, and AC Gold. All has been going well until this morning when I saw some discoloration on my leaves. They are about a week away from starting to flush.
Are my babies ok or do I need to take drastic measure before shit goes sideways?
(hopefully those pics came through to where you can see the purple on the edges)
Thanks in advance for any help/tips.
