yellow leaves on first week of flower

A lot of times some fan leaves will just do that on their own. It doesn't seem to be a lot of leaves, and most others look very healthy so I wouldn't worry about it too much.

Incorrect, not normal. What are you feeding and do you have the correct instruments to check ph and ppms of what you're feeding? Clearly lack of N or lockout. Will get worse if you don't correct the problem.. Being week one not good, that sativa has a long way to go.

i feed her an 1/8 dose of mg 15-30-15 up until two days before i induce flower this seems to be the normal pattern for all my plants. the leaves turn yellow almost instantly because of the switch to 12/12. this one my be a watering problem because the plant seems to be to light every morning when brought out into the light. must have gotten a root growth spurt because it seems to need water a lot more than when it was in veg. i ph my water to 6.3 every time i water but this one i started half way through veg cycle and ended up with ph fluctuation spots. don't have a ppm meter and really don't know what one is for i thought it was only for hydro.

yeah man i think also lack of N due to what ever reasons, i sufferd this fate on me last grow, she managed to get to the end but she was a indica strain and did not need as long as urs will,, this time i fed them in veg and there first 2 weeks of flower i continued with veg food so i had enough N to see her through, they do get worse as the weeks progress if u cant fix it, but saying that i got 4 ounces of top dry bud from my girl who was in a lot worse condition to urs !! so soilder on try get some more N in there so she as enough for the journey,, by the way i dont have a ppm meter either but they are a crucial bit of kit for those who have them as they can tell u how much food ( disolved )is in ur water, to much = nute burn to little means food defeicent, so noing the parts per million is rarther inportant when trying to diagnose any problems, i will buy one myself when i av the pennies!! anyhow back to ur yellow leaves maybe up ur ph to the more popular number of 6.5 see if this helps with uptake of ur badly needed NITROGEN !!! good look man hope it works out for ya and in my own personal experience it will m8. grow on, peace !!!!!!!!

try 1/2 of grow and 1/2 of bloom to see if its working. hopefully it will stop the N def process.

still continuing to get worse at the rate it is going there will no leaves left when done added a 1/8 dose of mg 15-30-15 this morning will see in a day or so how it does

looks just like my two sour diesels. they are lacking nutrients and saying they're hungry. i fed mine half dose for first time and it seems to be turning green again.

fertilizing did nothing except make the leaves even yellower. if a leaf is deficient should it not change back to green and not yellow

shit happens , just let it grow , she'll be fine

ya , don't want it to look like the ugly one in the back of one of my last pictures and get a gram of it so no she will not be fine

leaves are still continuing to get worse not normal still way to early to change.
