I did correct it that is why I keep using calmag bc I fig if it had a def then it must need it ???
there are many reason for a deficiency and lack of nutrient is only 1 in a million
the most common cause of deficiency is nutrient lockout
caused by ph swings
an overload of other nutrients etc.....
if you are using tap water I am more than certain you have enough....considering you are using Sunshine mix which has a Calcium additive in it....either gypsum or lime........
so ..............pull off any leaves that look bad......stick the the feeding chart
water till runoff and then let it alone to dry
(plants love the wet/dry cycle) it allows oxygen to the roots.....without oxygen at the roots.....plants die
once dry and light to the lift....completely saturate/soak the medium again....
always feed your plants
not flushing.....as there are no salts to build up
I believe you have recieved alot of bad information do to a lack of communication
be it not telling us exactly what you are using....."Medium.....coco loco or peat based potting mix?"
so....
from now on if you stick to the plan above you should be just fine
