What are grow media, nutrients, feed/water sched, ppm/ec, ph, temps, RH, light specs/distance? More info is better.

Are you using water from tap, RO, well, rain...?

Tap our water is perfect 7.0

U think It could be a ph problem?

U think It could be a ph problem?

My tap comes out at 8.5. I ph down my water and feed mix to 6.5. 7.0 is not ideal, but that shouldn't cause a big problem.

I'm used to Ca def looking more like splotches or speckles. Yours looks like more focused around the veins on the leaves.

If you supplement CaMag, the Ca comes from calcium nitrate, so you're adding nitrogen. You don't want to overdo it.

Are you measuring the ppm/ec on your feed mix?

So you recommend I add calmag but exactly as the bottle says? And do you recommend a good ppm tester

I use a cheap TDS ppm tester
HM Digital TDS-EZ Water Quality TDS Tester, 0-9990 ppm Measurement Range, 1 ppm Resolution, 3% Readout Accuracy https://www.amazon.com/dp/B002C0A7ZY/ref=cm_sw_r_apan_glt_fabc_BF2KWCSBRXW1PHEKS352?_encoding=UTF8&psc=1

I use botanicare calmag+. The recommended is 3ml to 5ml per gallon. I err to the low side on all my nutes. The recommended amounts on the bottles tend to be too high.

When I make my mix for plants that are at your stage in flower, I try to be around 1000ppm. Full strength nutes will put me closer to 1500ppm. Thats with 250ppm tap water.

I’m heading to the grow store now and had full intention to buy just that

And I’m feeding the calmag with every watering or only on days I use nutrients?

Be aware that botanicare calmag+ also has Fe iron supplemented.

I use it only when I feed.

GH Flora Series base indoor
GH Maxi base outdoor
Easy Weed soluble kelp
Soluble humic/fulvic
RAW Silica
Botanicare Calmag+

That's what I use for nutes

The plants are not finicky (well some strains are more forgiving than others). It's easy to overthink it and mess them up from trying too hard.

You should be aware of what is in each of the nutrients/supplements you are feeding your plants. Too much of something can cause problems just like not enough can cause problems. For me, it's better to err on the side of less, so as not to overdo it with too much.

Botanicare CalMag+, the plus variant of their CalMag product, has Iron added in addition to the CalMag. So just be aware that you are supplementing Ca, Mg, N, and Fe with that product.

The yellowing Is different,veins appear yellow? Mg deficiency veins remain green dont they?

Like @myke says^^^

It doesn't look clearly like CA def.
