I am currently on day 35 of flower and for the past week I've been noticing a yellowing on the leaves, but after opening my tent today I had noticed that a lot more leaves have turned yellow and some even died. I added alittle bit more nitrogen last feeding but it didn't seem to help. Maybe I need to add more? And some of it looks like light stress but after lifting my lights up I did notice any more light stress. I'm using 5 gal smart pot soil. And I'm using humboldt organic nutrient line. If you have any idea what could be going on please help a fellow farmer out!:bigjoint:

Day 35 isn't week 6, but if you were in week 6-7, it'd be natural if it were indica dominant or near the end of a flowering cycle. The flowers would drawing potassium and phosphorus abd such toward the buds.

Could be a ph problem. How often do you get runoff? I pull mine out & water them on the drain table once a week. It's a bit of a hassle, but only takes 30 mins. Good time to look them over and check for hermies, bugs, etc.
If you never get runoff, lockout is a possibility.

I've looked at chart before, but there's so many nutrient deficiencies that cause light color foliage it's hard to diagnose. And it's gorilla glue #4 so it's supposed to be a 10 week flower so that's why I'm concerned the early yellowing

I can dig it. Mine are leaning over and some buds are damn near parallel to the floor! I may have to install a net for the last two weeks. Gave em guano & kelp/alfalfa tea last week & buds are swelling...

What week are you? And on what strain? Waiting for some swell, myself.

Looks like a lockout ... Cal mag deficient in leaves .... Nitrogen being pulled from itself.
Plant unable to pull nutes from root zone NOW its feeding itself.
Leaves WILL not change back , but should stop more progression.

But .. If these are AUTOS ... They tend to go into fading anyways as it is hardwired at a certain lifespan.

I'm currently flushing my pots right now, I feed and water at 6.5 but my run off was at 7.0 and my ppms were really high at around 2,180

But the only problem is I have saucers under my pots but I can't take them out from underneath them so the run off just staying in the back plants.

Just an update! I flushed them and have been giving them nothing but PH'd water and it's slowly getting worse but it's definitely slowed down. I'm on day 47 and not sure what I should do at this point
