Just starting week 5 of flower and was told I should start to cut out the the cal-mag soon.
I am showing a few leaf issues on some plants which all look like calcium and magnesium issues. maybe little phosphorus. I am watering at 6.5-6.7 and getting run off at 6-6.3 on all plants 5ml cal per gallon. 3ml this last watering… Using RO water.
I am wondering if I top dress with some dolomite lime with cal in it will that satisfy any calcium needs from the Ro water? May a slight increase in soil ph possibly help with any deficiency I am seeing?
this plant #3 has always had issues. She did bounce back a few weeks ago but then nose dived again. Last to sprout and smallest of the bunch.
And here are a couple leaves off the other plants that have a few leaves with issues. However as a whole the plants look pretty good.( i am told)
