My girls stated going yellow a couple weeks ago with these brown spots showing up a few days ago. Any ideas what this could be? I've been using my regular schedule of 2 tbsp per gal of dr. Earth with some Neptune's harvest seaweed and fish fertilizer every 2-3 weeks. Only thing that has changed...

Okay, so I'm thinking this is a phosphorus deficiency but I'm not sure. I forgot to add lime to my soil so I had a slight cal deficiency. I added lime 2 tbsp per gal and think I may have went a lil overboard by giving them cal mag 1/4tsp per gal and locked something out... What do you guy's think?

Okay guys, so I mixed up too much soil 5 weeks ago with dr. Earth. My question is, will it still be good? It's been moist since I mixed it so I'm sure the soil is still alive. Would the soil become too hot? I've heard of over cooking soil and I don't want to use it if that is the case.

Hey guy's and gal's, I recently decided to get back into growing.. Been around 7 years since my last grow. So just a heads up I will probably have a ton of questions along the way. I've spent a good part of the past 2 months on here reading and soaking in all of the knowledge that's on RIU to...

Hey guy's, came across this light on Amazon. Thinking for the price it'd be a decent veg light for my 3x3 veg tent. Anyone have this light or run phlizon lights? Comes with a 3 yr warranty too. https://www.amazon.com/gp/aw/d/B08GCKPBSQ/ref=ox_sc_act_image_1?smid=AH440WDUIAWYA&psc=1
