Helpp lol. It’s in a 3 gallon grow bag. Major yellowing greenish leaves bottom and mid way up plant. I’ve been feeding 1/2 tsp of this 4-0-1 in 2 litres of water maybe once a week. Ph usually ranges around 6.5 give or take a decimal point. I’m using 2 1000w (360 actual watts together) 18-6. 40”x40”x80” tent. 50-60% humidity usually and around 80 Fahrenheit
I go to work for a day and a half at some times so I have to slow release water with a 2l bottle I know that’s not good but when I get home I usually wait till she’s thirsty again before I water. I’m wondering it’s gotten colder here the past week could that be a possibility? Im now adding 3/4 tsp of the 4-0-1 and 1/4 tsp of this 12-4-8 miracle gro as it has added micro nutrients that I don’t believe I have with the 4-0-1. as of seeing this problem yesterday I just want to know if I’m on the right path of maybe finding out the problem.

If you're in coco try some calmag. Seems like you have enough nitrogen according to your nutes.

I'm still a beginner too though. GL!
