well there is no way to control the two right? buying DI water is not an option - this is meant to be a low cost maintenance tank.
if the mag is coming from the tap then nothing i can do about it. the only way i can control it is limit mag from the Kent fert by dosing less.
I'll just live with the problem i guess. maybe not all leaves will curl.
Hard water is not really a problem. I had well water with 21 degrees of hardness and plants grew amazingly well in that tank. Best plants I've ever grown really.
DI is one way to alter the ratio, but so is adding Ca and stopping any Mg addition. Before you start changing Ca:Mg ratios though, why not take a water sample to the LFS and have them test it for free. Ask them to do a Ca test and a GH test. We can calculate what the Mg is from those two numbers. You may not have a problem with Ca:Mg at all.
Also, the curling you are seeing isn't quite bad enough to really definitively identify it as a deficiency. More time is needed to say for sure.
Yeah, leaves arent curling any more - must have been a shipping stress thing as the plants put out only 2-3 curled leaves before putting out good looking ones.
however now my older and even medium-age leaves are starting to get holes in them. it's like the tissue is thinning out and the net venation of the leaf is starting to get holey and the tissue is thinning out until holes appear. am i not fertilizing enough? the oldest leaves are turning yellow which i think may be normal since they are old, but am not sure.
dang, you really think so? i only have 3 BN pleco juveniles in here and i was hoping that when i reduced their numbers from 70+ to 3 that the plant eating would stop. i guess not lol. i never see them eating it though so it must be at night.
my other 6 plecos are all carnivorous hypancistrus so they wouldn't touch my plants.
turns out, i was missing Potassium...i checked all my ferts and that was the only missing nutrient - an important one too.
got some today.
swords look horrendous. old leaves are dying, holes, yellow, death, horrible...x_x
potassium deficiency makes sense, I will update on it once it gets going again.
