So I’m currently growing some bad azz og cheese and I’m day 36 in flower and I have some yellowing starting to happen on the top fan leaves. I’m growing in pro mix ewc and some dr earth buds and bloom fertilizer. 2x2x5 tent 2 900 watt phlizon led lights. Is it normal to start yellowing this early in flower? Or am I lacking in nutes? Temp staying around 73 to 75 rh at 49% never above 55%. Got good air flow.

Looks like they were overfed at some point and now they're getting too much P. Balance is what you want.

I'm also not a fan of amending a soilless medium like promix with dry nutrients. Some make it work but many have issues. Liquid feeding seems to be the most forgiving and successful for most people.

I really think it’s a cal mag issue since I’m using purified water but I may be wrong

2nd what @xtsho said. Looks like too much P too early. Causes interveinal chlorosis of the newer leaves. Typically in the top fan leaves first.

How close are your lights and how often do you water?with and without nutes?

My lights are about 14 inches away and I water when the plant tells me it needs water I have good watering habits for sure when the plant drops she’s thirsty 30 mins after I water she’s standing up I know when it water

Okay but waiting til leaf drooping to water is not so good, maybe a couple times to trick the plant lol but you should water with the finger test you can go up to the 2nd knuckle and see if it’s dry or not and that will give you more of sign on when to water regularly. Also go lighter on the flowering nutes I see top burn everywhere, if your using neutral ph water no need to ph it. Root and soil organics will buffer it.

I water when the pot feels light I don’t do the ginger test I don’t think it’s very sufficient

Finger test I meant and i ph my water bc I use tap water with a pur filter on it that does not mean that my ph is good just removes the chlorine
