Nugs, probably a calcium deficiency from early on, where you knocked off a growth point and it never healed. Everything and anything probably climbed in afterwards. Take a close look. See if it is on the top, bottom or middle where the rot is. I bet it is on top, right where that wound was...
Soil analysis would be easier, but I would imagine that you have too much K against P, due to low Ca and high Mg, probably overwatering and most definitely Mn and Zn problems, might be B too. Any conductivity numbers from the runout?
Roco,
Read that post above by sister Mary and shot hole on page 735. Lay off the Mg, that is the problem, too much most likely and low Ca. Add gypsum and fine lime and milk.
Calcium problem, plants are growing too fast and can't pick up calcium fast enough. How is your boron level in the soil? Do you have a soil analysis? Are you using nitrates? There is a visual zinc deficiency, I see lots of grass, that means high K and little Ca, some serious taco going...
It is breakdown, you have the same issue at the roots. What you see above is happening below. Note the fern. Ferns hate calcium. You need calcium to make the roots strong and to multiply. They probably are just breaking into the nasty subsoil below and waterlogged. There is an oak leaf...
We use citric acid weekly on grapes via the irrigation system. It is spectacular. I am not sure if it is the adsorbtion of vit c or the nice acidic pH twang. The grapes from these farms is spectacular. For those metric folk, we use 2 kgs/HA/week with 1600 grape plants per ha.
Horse tail is excellent. Works better if you start early though... The potassium bicarbonate (Green whatever) and the calcium carbonate (hi pH) kill. Horse tail is a natural form of silica.
If you get your copper and manganese high enough in the plant you won't have PM. In the meantime, Calcium oxide mixed into water to get a pH of 11 works wonders.
Manganese and copper foliar will help a lot. If your copper and manganese are high enough, you can't get PW. The more your soil is balanced the less problems you will have. If you are in GA, you are probably sitting in a lot of iron, which is the enemy (antagonistic) to manganese...
Do you have a soil analysis? I see on the tomato to the right a blaring calcium problem. I think this is calcium issue and it may be that there is too much water and not enough drainage. I would drill a lot of holes in that pot.
Haight,
This may mean that you have your conductivity too high or in general, too high K and Na compared to Ca. It is critical in soils and mediums to not overwater, otherwise you are guaranteeing yourself calcium deficiency. If you don't like what you see when holding back water, you may...
That stuff doesn't look like there is any calcium amendments. Send a sample quickly to spectrum analytic in ohio and get a soil analysis run, both M3 and [email protected], plus nitrogens, aluminum and sodium. Post it, let's dial it in.
Calcium is the first element needed by roots. No calcium, no growth. There after a bit of P always brings up carbohydrates and forces more roots. Unless you were planting into a huge amount of P, which no one usually has, you might be correct. As for calcium, no, everyone needs calcium.
