3 days ago using Dr Earth 394. I used 6 tablespoons as directed and about the same with worm castings. No others nuts besides Dr Earth and castings
Yep, definitely a N issue. now to figure out whether its due to an abundance of something else effecting uptake, lockout due to pH swings or straight deficiency. The joys of growing hey.
My ph is always 6.3 to 6.4
have you got access to liquid activated organic compost locally? Most are heavier in N without overloading P or K. Does well in organic potting mixes and will tie the plant over until top dress is available and worked its way through the medium. Leaves already at the stage of late yelowing or necrosis will not repair themselves though.
I'd have to call around. Is there a brand that's better than others? I really want to stay away from synthetics.
Sorry, I'm in Aus so I don't know whats out there in your neck of the woods. What I use is basically a compost tea pre prepared by a local nursery/farm. It is a 12:2:5 and works well when Nitrogen is lacking but PK is adequate.
It's spreading. Currently using Dr Earth. It worked perfectly until I screwed up. I've never tried Epsom salt. I flushed the hell out of them thinking I had to with a ppm at 18 to 1900. Boy was I wrong. They were going great until then. No issues whatsoever. I need to fix this problem. I just top dressed like 4 days ago. Watered 3 times since. They were getting dry.
For a soil grow, my source water pH is set to 6.6 and I've not had any problems. A pH of 6.3 to 6.4 might be restricting the uptake of P, Ca & Mg.
How much Epsom
Go by the instructions I think mine says a quarter cup per gallon but I would half that and make sure it’s plant epsom salt and not just bath salts lol
When you describe that you are in week 3, the peak or just past peak of stretch, and it looks like this, it is simply needing more food. While you see N missing, it's not always so simple when the plant wants to keep eating a full meal each time. I would increase feed. If you topdress only you might want to bottle feed while waiting on it to work. Week 3 is not too late to add N, but I would NOT add an unbalanced high N feed like 12 2 2 or the like. 4 4 4 is fine, any variation of it.
Just top dressed
