Question About Potassium Defeciency

Hello All,

I have some leaves that are an exact match for Potassium Deficiency in this chart :

View attachment 1986335

I have Tiger Bloom (2/8/4), and Cha-Ching (9/50/10). Everything else looks pretty good. I am afraid that I may nute burn the rest by trying to catch up the potassium using what I have. Anyone agree? Recommend a potassium only substitution?

GD! I hate it when I start a thread and THEN go looking for my own answer. Wiki says:

Prevention and cure can be achieved in the shorter term by adding potassium-specific fertilizer, often called potash, which consists of K[SUB]2[/SUB]CO[SUB]3[/SUB].[SUP][3][/SUP] Rock potash may be a good solution because it has a high potassium content but is released slowly to reduce overdose. Common forms of inorganic fertilizers include potassium nitrate, potassium sulfate, and monopotassium phosphate. Other potassium-rich treatments include feeding with home-made comfrey liquid, adding seaweed meal, composted bracken, compost rich in decayed banana peels, or other organic potassium-rich fertilizers. Wood ash has high potassium content, but should be composted first as it is in a highly soluble form. Adequate moisture is necessary for effective potassium uptake; low soil water reduces K uptake by plant roots. Limiting acidic soils will also increase K retention in the soil by reducing leaching.[SUP][1][/SUP] In the longer term the soil structure should be improved by adding plenty of well rotted compost or manure. Additionally, improving soil structure will help reduce leaching.



Thanks for looking, sorry for wasting your time................I just love you so much!

ProTekt from Dyna Gro is a good source of K although it is intended as a silica supplement. That would be one of the fastest and the silica is good for the plant.

Kelp meal or liquid kelp. Not as fast, but good stuff.
