The growth tips on my plants are super lime green compared to the rest of the leaves. Is this a problem? I'm growing in FFOF and I've given very little CalMag and P-T-K so far.
Morning Mate, IDK... looking like fresh exposed shoots. Via the pics I do not think that you have a problem, green of the fan leaves is maybe a bit dark but nothing to worry I'd say.
Good Luck for the rest of the way!
