Dynagro is under-rated as fuck

When they were looking hungry for N on Sunday, they didn't need to be watered. But I was going out of town and mixed up one gallon split between 3 plants of 3 ml grow, 2.5 ml protekt and .75 of mag plus. Sorry, looked on the hydro, not soil chart when I posted before so it was .75, not 1 ml of mag plus. Plus .4 ml of drip clean. The watering prior, Fri as I recall so just a couple days before, was just water. Six days prior to that was the dyna regiment but about 3/4 the dose of each.

So you don't see cal deficiency?

I had a potted zucchini plant with blossom end-rot this year. I gave it one gallon of water containing 10mls of calmag, I grew baseball bats for the rest of the summer. Considering this zucchini plant grew leaves as big as your torso with 3 pound fruits hanging off of it, I seriously question much calcium a ten inch tall cannabis plant actually needs considering it's already being supplied in the plant food.

Yep, reason for my comment.

Love summer squash and usually don't have a problem with blossom end rot on maters or squash. Main enemies of maters - mites; squash - PM.

Ive gone and tried alot of different nutes in the last 10 years or so. I have run DG nutes and they did ok. Not great but not horrible. I seem to always find my best results in hydro and aero come from using Fox Farm 3 bottle combo with additives. I have now also come to like umboldts Own Fusion line of nutes. I don't care much for Advance Nutes didn't see much to be excited by with the cost to output on them. I didn't really like the outcome of GH nutes that much either.I do like Canna lines but the price doesn't really justify over other nutes.

UB, I was looking at my plants and the ever present chart of common nute issues. It has Cal def but not excess. From looking at mine, in person, not what shows on a camera, closest things appeared to be cal and mag deficiency. But I am not buying it since the plants shouldn't be hungry for it. I have made some fixes and hopefully am on track!

As for tomatoes, our problem is that it is cold outside and we still have some growing! My wife pulled seed from some pricy grocery store ones. Didn't yield enough but used up some of my fox farms I don't use anymore.

Here are some pics of some leaves I cut today that show what I am seeing. UB - I lied, No Cal def on the chart. I must have been referring to some pics when I was googling. So I just compared these leaves to the chart and I can't figure it out. Would love any opinions, looks to me like a bunch of deficiencies, but none too severe.

Hard to say without knowing your day to day activities and at what location on the plant those leaves came from.

I still think the issue is your lime. too much Calcium disproportionate to other elements can cause Boron/Magnesium/Phosphorus deficiency and too much Magnesium disproportionate to other elements can cause Calcium/Potassium deficiency

Day to day activities are none really. I had been doing a lot of LST but that is about it. I don't prune, foliar feed or anything like that. Just water/feed when they get dry.

The plants aren't very tall due to the LST. The leaves cut were what would call mid range, not newest or oldest grow.

lmaulle - if correct, what would you recommend I do. The lime is mixed into the soil. Dyna-gro grow has the calcium that's in it. I don't think I am ready to pass on the N....

The ratio of K2O:Ca:Mg is critical to not having nutrient lockout. From experimenting with my own mixes and looking at others' recipes, the best K2O:Ca:Mg ratio is give or take around:

K2O:Ca:Mg = 1 : 0.5 : 0.16

Ca:Mg should be between somewhere between 1:0.25 and 1:0.35

Too much Ca relative to K2O and Mg will definitely show as deficiency.

The majority of your N in hydro comes from calcium nitrate and potassium nitrate. In order to increase N without throwing off pH, potassium and calcium must be added as well. The micro bottle in 3 part systems provides the majority of the nitrogen. That's mostly calcium nitrate. The green bottle provides more potassium than nitrogen. That's potassium nitrate.

potassium nitrate NPK = 13-0-44
greenhouse grade calcium nitrate = 15.5-0-0 + 19% Ca

To HB or UB......This round my clones got switched to the foliage pro and protekt instead of the grow. Took me a sec to redial my ratios but I'm liking it now. From what what I've gathered the best combo found SO FAR is FP and protekt in veg, then varying ratios of grow/bloom/ProTekt in flower? Would you say this is accurate? I LOVE using the grow/bloom in flower. Best final product so far.

I've used dyna-gro with coco plus cal-mag and it did not do bad but personally I've had noticeably better results with general hydroponics flora series plus cal-mag. Although general hydroponics does cost more.

What is a "cal-mag" deficiency anyway? The GH flora micro bottle is where you should get your calcium if you're using their 3 part system. If you really do have calcium deficiency, you should use more of the "micro" bottle. The worst part is when the problem goes away after adding cal-mag+, people conclude "yep, i had a cal-mag deficiency" as if that's even a thing, then keep buying the product.

There must be an army of paid shills who insist everyone needs a product called cal-mag+ in their arsenals. When I started growing, we didn't have cal-mag+, we had nutrients. Now, I tell people exactly what's inside it, and people will just ignore me and get cal-mag+ anyway. Biggest ripoff product on the market. It's just some calcium nitrate and magnesium nitrate with iron chelates.

It's so simple, it repels the mind.

If you're in hydro, I'd agree. In promix, fp or grow works a lot better than combos of grow/bloom during flowering.
