Leaves limp & yellow

hey hopefully you guys can help me, here’s the run down:
My leaves are yellow & limp

3-4 weeks left in flower
Water always ph’ed between 6-6.8 (I aim for 6.3)
Nutrients I use are GH Maxibloom, cal mag, sometimes recharge and some pk boosters
EC 1-1.3
And I water when dry

First I thought it was the light, raised it all the way up, turned it down. Problem continued.

I noticed alittle burning and crispy leaves so I thought maybe nutrient burn, so I gave it plain ph’ed water with some calmag ( in case it was a calmag deficiency). problem continues.

They stay droopy even 2-3 days after a light watering

I’m not sure if it’s the plant naturally getting closer to harvest that’s making it yellow but it’s only 2/3 plants, the 3rd one is still green in the front right

I know they’ll make it to harvest just fine but it’ll probably be less of a harvest. Any thoughts on this?? Thank you


I don’t use GH nutes at all but I do know maxi bloom is very low in nitrogen and these plants imo are definitely asking for nitrogen even tho they are in flower some plants just want more some times when I did 1st start growing I used GH 3 part nutrients there grow,bloom,and micro was never realy happy with there nutes and my plants burned easy from it also have you measured your run off ph and ppm I would definitely water till you get enough run off 10% roughly and see what the ph and ppm is sitting at these plants look like they have weeks left before done

@Munchable I’d look at your tent temp/humidity and also make sure your pulling in some fresh air. Flowering takes more water and needs intense light, more intense than during veg.
Drop them down till your ppfd is around 1000 at it’s highest level. Usually around 12 inches.

But make sure your temps between 72-85 and plenty of fresh air pulled into and out of your tent.

You can also give them a little molasses in your feeding. Good ph and the molasses is high in micronutrients and sugars. Boosts energy. My plants love the boost when feeling down. Also pretty darn natural.

I would be leaning towards potassium and phosphorus deficiency or either one of them cause they dont need as much nitrogen in flower

I’m with @Myfriendis410 , a support ticket would help isolate the issue. You’re going to get multiple different responses without enough info to go on :love_you_gesture:
