Had some major problems this week with 3 out the 4 plants I’ve got in my grow rent at the moment.
I noticed over night about 6 days ago some yellowing of the top leafs which was telling me there was problems with the Ph in the soil , the Ph was well above 7 ! #1 was affected less then #2
I’ve had to flush with Ph adjusted R/O water at 5.1 Ph , I’ve done this 3 times over the last 6 days , am now doing double feed’s few a few days now (also Ph adjusted to around 5.8)
Everything seems to be responding and the Ph in the soil/coco is around 6.5 , so hopefully problem solved
Will veg for probably 2 more weeks , so see how we go !
Started LST on them bottom branches
