79-85F 45-50Rh lights 240x5 @ 18-22" :great air flow. watering when dry to runoff. 3 days.
Week 4 flower.
Fox farms nutrients.
pictures make it look much yellower due to lights. But there is discoloration.
So I have a some stuff going on with a few plants. yellowing on some top leaves. with tip curling up. none on the bottom. Some spots orange/red I took for cal/mag issues which i am seeing on some other plant as well. Good growth otherwise.
this upper leaf discoloration I noticed is going back about 10-12 days. it has had a flush on the 14th.
ph in at 6.5-.6.1 with runoff numbers steady 6.0-6.1 .
noticed it getting worse after flush so gave a shot of nutrients @ 2/3 last watering thinking it maybe hungry after flush. ppm in/out 1350/1500.
Could this be light stress?
Plant 12: same environment as above.
this plant has some yellowing also. with same spots/ curling down and up leaves.
Same deal. saw the yellowing thought it might be hungry but after feeding got a little claw.
Ph. history in/out 6.5-6.6 / 6.0.-6.1 looking back ppm out on this plant prior to flush seemed to be getting higher.
Plant 5: not remotely close to looking as yellow as photo appears.
same ph numbers roughly.
had higher Ppm runoff prior to flush.
some tips issues and red/orange spots.
Same as above
Any advice is greatly appreciated.
