From "week 4" challenges from the past. WAnt to flip[ the script ands see what it ends like. My plant seem to need it. the other plants, the one next to it,,the soil got spiked by a silica overdose. liitle up there.. 7.2pH sooOOooooOooo checky that soily before adding the Calciumy
I’m more curious about why he used to be anti calcium during flowering.
Anti Calcium Carbonate found in my tap water. To long of a story for this thread.
Here's a great article. Only problem... no actual data.
I have it saved and that article fu ked me up big time
Can you explain further?
edit: The short answer is the article (if we're talking about the same article) was written by a scientist. She explains how our flowers during Veg will hardly react to a little calcium. It's when they change, the flip to flower, is when that reaction comes to light. (I'd have to read that article again but it seems like she was dealing with a toxicity issue but her findings were based off a study) Most growers (young growers) find that problems usually hit by the 4th week of flower. She believes it's the calcium. She explains in detail as to why if I could find that copy I'll paste it here but I was sold on the idea. Now I'm finding that.( a year later) calcium is important during the first 4 weeks of flowering. From multiple sources. the second half of flower magnesium and potassium is the important nutrient. Got Langbeinite?
And that's the article, finally had a chance to read it and yes thats that same article that was in Maximum Yield. It's a little misleading on a first read. If you read it again on the context of Calcium Toxicity then it would make more sense vs just reading it as an anti Calcium article. Dealing with tap water with a high ppm (350) and then reading that article can cause some alarm to a few growers, it did to me. So a year later I've had lots of success using RO filtered water negating some of the problem solving without the tap water in the equation. My tap is high in Calcium Carbonate but I'm suspecting that the ions of that calcium bind with the calcium in the pots causing them to lockup in the soil. Nothing proven just a suspicion. With the better experience/luck using RO filtered water it only strengthens my thoughts on that.
Who are you listening to? You should listen to me. This is my own experiment by adding calcium sulfate dihydrate. As soon as I came to read your comment. I have experimented with adding 130 ppm calcium sulfate from regular nutrition. Today is the 11th day since it was added. The plants continued to show signs of potassium deficiency. Within 10 days, I added gypsum to the peat moss mixture. The water output is more than 100% every time the gypsum is fed as shown in the picture below. If the plant cannot absorb it quickly enough will not show symptoms of potassium deficiency yes or no ?
I probably already mentioned it, but a light feed of Amino Acids (soybean based) could probably help here. There's a few products out there that include soybean amino acids, beneficial bacteria included.. etc. that are worthwhile looking into. The Amino Acids will unlock nutrients bonded to the soil for easier plant uptake. Worth a look.
