Hi
I adjust my nutrient to pH 5.8. I water every 2nd day. I get a little runoff, but not much. I did a second water today so I'd get a decent amount of run off so I could check it. The runoff pH was 4.8.
Should I be concerned about this reading? I ask because I'm starting to get a touch of yellowing on a few fan leaves, and I suspect it's magnesium lock-out due to the coco pH being too low. Bit hard to see on the pic, but it's there.
Coco with 25 % perlite and worm castings.
Nutrifield Coco A+B at 1/2 strength.
Nutrifield Fulife at full strength.
Flairform CMX (cal & mag) and Flairform Budstorm (P & K) at full strength
OGP Original organic growth promotant.
Seasol seaweed extract.
Should I do a flush, water more to get more runoff, or adjust the nutrient less to get a higher pH in my nutrient, or all of the above?
Also, should I be feeding at every watering? I figure that running 1/2 strength nutes at every watering is OK?
Overall, do the girls seem to be OK for just starting 3rd week of flowering?
