Medium: Foxfarm Happy Frog Nutrients: Foxfarm Grow Big and Foxfarm Big Bloom Lights 2 T8 Flourescent Temps: Lower Temperature range Environment: Tent Water: City Water Problem: About a week ago I watered my babies for the first time in literally a month (they are in 5 gallon pots). They were very dry so water ran straight through them (because of this I watered extra heavy doing another watering after 30 mins). Since then, I have cloned them and everything is still growing fine but I am seeing this rusty looking growth on the leaves... Here are some pics... Anyone know whats up with them?
How do I fix that? I have a bottle of micronutrient solution that is called spray and grow or something...
