I'm assuming your in foxfarm soil of some sort? Are you ph'ing? If you awnsered yes to these questions read tread "foxfarm soils and pH" this will help.

It appears to be a common problem using foxfarm soil, you should not pH at all.....that being said I don't know anything about mg organics. I would suggest getting a good digital soil pH tester. If your soil pH is around 4.8 to 5.4 I think it is the same problem as foxfarm soils. You could also test your runoff but you check your water before you flush, then run enough water through then collect some of the runoff. Then you figure your pH runoff is your average. Let's say your water is pH of 8.0, then your runoff is 7.0, this would make your soul pH 6.0.

To be honest it certainly looks like a few nutrient def's & sorry to put a downer on ya day !


But it is not uncommon for plants to pull nutrient reserves from the leafs from mid flowering onwards... that is a plus

We could look at the following...

75% strength nutrients used may suggest under feeding ?

PH of soil is not suitable ?

That may be due to regular feeding of nutrients every watering etc which has caused a nutrient lock out by excessive nutrients available in soil turning more acidic !


How ever it looks like you only have a few weeks to go & i'm sure the girls will survive that long...
