AsNoriuanswered grow question 9 months ago Older girl is max 2 weeks old, so how you can spray every two ??
Would not spray girls with anything except right ph water till week 3-4 of veg, then you can do prevention with neem, or other foliage boosting/feeding
Now with state. Aftermath of overwatering, they have to have cycle wet/dry/wet/dry and etc.
Keeping pot humid can play up with ph, o leave eoots without oxygen, then you have such look.
Not a biggie, correct watering habits and they will thrive !
