I think I'm into flowering help

Before adding cal-mag......what kind of aquifer do you have that you get your well water from?.....if like mine there might be a lot of calcium in it already..if anything it's probably got a fair amount of minerals no mater what.....the less you put in, the easier it is to figure out what's going wrong.

I don't have any cal mag can I use anything else? If not I'll pick up some how often do I use this? And should I use it on all of them?
Thanks

One spot on one older leaf is not to worry about....there's no spotting on the other parts or on the other plants, no need at this point in my opinion.....as far as a cal-mag substitute......plain Epsom salts ( no fragrence)

Is there a way to test my will water for cal. ?
And if I use Epsom salt what amount for a gal water? How does this effect PH? I tested the water with TDS meter ppm 150.

Other than sending your water in for analysis, no real reliable way to figure it out.....that's why a lot of us use distilled or RO water....we know what's NOT in it.
Most nutrient lines for cannabis will be at least real close to having all that's needed, OF soil will have some calcium available as well...I use the HF soil in my autopots ( a bit milder than OF ) and the only reason I add epsom is because I'm using the old 1 part version that wasn't completely dialed in for cannabis at a rate of .5 gram per gallon with 4.5 gram of Mega Crop.......testing pH should always be the last step before giving to your plants, so what effect it has really doesn't matter....

edit: of course there are going to be problem plants that will drive you nuts....out of the 6 I have going, 1 is just crazy yellowing, spotting etc....while the other 5 are doing great, try not to let it bother you too much.. :smoking:

I suggest you at least grab a bottle of calmag just in case so you have it on hand. Using the trio i have needed it in every grow and i use OF as well. Once it is deficient you want to take care of the problem as quickly as possible or else itll get out of control quick.

@Son of Hobbes , @Mañ'O'Green care to chime in on this?

Should I keep feeding these 2 or should I switch to just water??
pics aren’t great but hey ho.

edit… I’m only using megacrop I don’t have any bloom nutes unfortunately.

The spots are from calcium def. You have calmag? If so give that with next feeding as well.

IMPO the problem is too much N and Ca already. You see how the crown is beginning to show a macro-deficiency that is not because there is not enough in the pot. It is getting locked up. Most new growers over feed. I would just go water, water, water, feed @50% strength repeat.

If your lights are at still at 400 PPFP then I would turn it up. Those girls should be ready for 700-800 at 18/6. Proper pH and light feeds to start. I feed every other water in a peat based Soil.
