Runtz, yellow leaves, nitrogen really only problem?

Is it only a nitrogen deficiency or is somthing else doing wrong. Been watering with worm castings tea but do i need to take step further. Currently using hawaiian super poop potting mix

Pretty sure that mix is coco based,; what’s the ph of the water and how often are you watering? Others know more about coco than me. They look hungry.

So we recently had some record setting rain fall. And i collected as much as i could and had been using that for last 2 weeks in sealed 1.5 litter water bottles. Ive been getting feeling my ph meeter is really only good for measuring light and moisture. And that i may be better just buying stripsm But here r results.

Im watering once every 5 to 6 days. However i do not have a larger enough run off tray to tell just how much is falling through. I would estimate about .5 liter of water each watering.

Get rid of that meter, I had one, they are not very accurate. What nutes are you adding? Add your nutes to the water, then ph it to about 5.9, that’s for a coco based media. Coco should not dry out.
