Looking at the charts I would guess nitrogen deficiency. I’m still learning though..

@ohigrow Thank you I’m gona give her a bit more “grow”nutes and see if maybe she will pull out of it. I’m gona move my light up a bit also just in case that is my problem

if this is happening more on the top of the plant it could be from light stress, you may need to dim your lights. more pictures and more info about your environment and grow style will help to diagnose the issue.

@one-eyed-cat thank you I have 4 plants in a 3×3 300 watt mars hydro light. At 75 percent power. This plant is the tallest one and none others are showing these signs of yellowing. It’s the tallest plant I’ve ever grown and it’s closer to the light than I’ve ever had a plant. My humidity and temps are spot on with the 69 controller. I use ocean forest and andvanced nutrients ph balance 3 part nutes. Sensi cal mag. Thanks I will move my light further away and see. THANK YOU!

@scottyreal thanks Scotty I have some botanical gardens “ mag-sulfur” additive that I use instead of cal mag from week 5 on during flower. But I just used some Epsom salts yesterday and hopefully that will help my girl. You rock thanks growmie

@scottyreal THANK YOU !! That was the problem and after two waterings with Epsom salts she turned around and now growing fat buds. You rock THanks again!

Look the plant is yellow from lock out. What media are you growing in? I would prepare 1 gallon of water , pH’d to 6.5, then sit my plant in it until saturated. Let drain on its side. Then wait. Don’t do anything without taking time to check. Also you may need to recalibrate your pH pen.

@ddubya04 thanks but no thanks. @scottyreal recommend Epsom salts for a magnesium deficiency and that was spot on what it needed. That fixed my problem !! If I would have listened to you my plant would have suffered more!
