I've been giving cal/mg every other watering at 1ml per liter. Will up the dose a bit.
Was giving calmag every other, will now with every watering. Thanks.
1.5ml/L is usual dosage I think?
Here are more pics. I've never had this issue but knew it was likely to happen at some point. Thanks for looking. It is on the smaller upper colas, not the large main buds &1 plant only. I gave calmag at lights on/watering.Everything else looks great.
Calmag deficiencies were something I heard mention of before, but it didn’t affect me growing outside. Knowing it would show at some point since starting indoors, I supplemented every other water and had no issue during the first grow. Is this something best prevented with prophylactic treatments or is it better treated when it shows? Same thought – does it hurt to supplement ca/mg plants that don’t show a deficiency? Thank you, I appreciate the help.
sometimes excess cal can do the same symptoms on the leaves but would be (k) defs on lower leaves, some People have enough cal mag in their water supply , some nutrients also have plenty onboard too
The bottom leaves look good, all green no rust or yellowing. Greener than I would expect at this stage. Can get a pic tonight if wanted. Here is a pic of the ww from the 26th. I was wondering if its the calmag keeping them greener? Usually I have some yellowing on the lower fans before now. The rust is only on the 1 of 4 plants, all four are different strains. The rust is not effecting the whole plant, only the smaller to mid size tops of buds on the white w. the mains are large and look fantastic.how is the bottom leaves looking ? , can you do a pic of the full plant in pot
and too much mag will block the cal at the top
While too much magnesium for plants does not directly affect plant production, it can cause deficiencies in the other nutrients in the soil such as calcium and potassium. When too much magnesium contributes to a deficiency in calcium
, not a big issue > i just finished a ww and she give me a load of def leaves , fussy with too little and fussy with a bit too much .
As long as you are giving maintenance doses of calmag, especially on hungry plants such as WW, it doesn't hurt to proactively dose... but then you don't know how close to that line you are, and maybe are wasting money giving supplements that are not needed. I gave calmag once on my present grow and then stopped using it as soon as that problem cleared up. Usually, once a plant shows a need for extra, that need continues for the rest of the grow.The bottom leaves look good, all green no rust or yellowing. Greener than I would expect at this stage.

If I understand - best to minimally supplement, then treat individually with more calmag if needed?? Thanks
I've started adding calmag with every water, 1ml per L. for the remainder of this grow. I would like to get a better understanding of the plants needs for future indoor grows. Specifically - do I supplement from the beginning or wait until there is a deficiency and then treat individually?I would almost ride it out as it looks super
do you know if your in hard or soft water , and do your nutes hold cal and mag , my ppm is only 40/45 from the tap , when i grow synthetic i never have to add cal/mag because the nutes have enough to do
Nice job , it looked worse than it is
The bigger stuff on the same plant shows no deficiencies at all. That's what seems odd to me.
