a lot of yellow and light green leaves 5th week in flowering

im using soil a mix of fox farm and perlite 1000w hps and the temps go from 75-88f. there are two plants both are bagseed so I don't know the genetics but I can tell from the smell they are different strains. any help is appreciated.

2nd plant 85.jpg dc.jpg photo5.jpg s.jpg

the first plant isn't as bad with the yellowing leaves as the 1st one

Too late to do anything about it. Just ride or out Egor. Yellow leaves are common during the later stage anyhow Egor.

week 4 or 5 and week 8 or 10 you see things like this. most of the time its normal. You could try to sprinkle a little bloodmeal on the soil and water like you normally would its fast acting.

I am going threw this right now. 3 weeks into flower. It is normal but damn. I very seldom loose more then a dozen fan leaves in the whole grow till the end. On 4 plants i just got threw picking about 1/2 a coffee can full of them. I am running temps just a bit higher then yous but this aint my first rodeo and can always fix my problems. The leaves are like totally out of nitrogen. They die slow once they get a little yellow it takes 7-10 days or more to change. Has me stumped. Mainly because it is only a little over 3 weeks into flower.:cry:

if your useing soil add some bloodmeal if you using hydro use some nitro

Yeah I know what you mean, I've been picking a lot of yellow leaves too and it might have something to do with the high temps

nitrogen def, will start at bottom; old growth.
Besides that N is needed by the plant it is also need to prevent ratio imbalance and nutrient antagonism and PH dropping too far, all results in reduced overall nutrient uptake. My guess is the OP used too much P and K (not just in total level but also relatively to N), i.e. bloom product preventing proper nutrient uptake of various elements including cal and mag. Those are deficient in the plant, but can be fixed/prevented by adding N to the medium. Magic. Almost.
 
Thanks for all the responses ima just go buy so bloodmeal to up the nitrogen and hopefully it will stop the greener leaves from turning yellow

some of those yellow leaves will turn green again if you give it some N maybe not all but it will look better within a few days.
