Looks like a nitrogen defiency or possibly magnesium. When mine start to look like that i correct it with a teaspoon of cal mag in a gallon or epsom salts.
Yeah I planted them from seed into their final pot. I havent used any nutes, topdressed with ffof. Gonna use a very little bit of nutes in mid flower. What and how is the best way to add epsom salts??
If you use ph down, it may be a micro nutrient difiency. My tap water comes out at like 8.5 - 9.0. Usually about two or three weeks in, if I dont use cal mag. My plants start looking like yours. Now I just start cal mag at like two weeks.
When does using CO2 become detramental? I know you dont need to in a 2x4 under a 300 watt light. When must you use CO2? Is there like a certain wattage and up that determines when to start using CO2.
Gonna run it in my 4x4, still picking a strain though. 2 Photoperiods in 7 gallon pots. Very excited to use the fd6000 0. I already know these are gonna be the best flowers ive ever ran. Thank you.
