coco perlite

[OXOSSI]

Can anyone diagnose? Few new leaves turning yellow and new shoots look curled and crumpled. It is my first grow in perlite coco and had some pH problems previously. Added NPK 10-10-10 with a bit of worm castings tea. PH came out just below 7. too high? calcium?

You want to get your PH lower than that for coco.
Looks to me like you over fed them.
Flush the medium out with plain water ph'd to 5.8 to 6.3.
Did you reveg this plant? what's up with the single leafs?






good luck!

Flushing with plain water will starve the plant. The beauty of coir is the low CEC, if you muck up, simply remix feed properly and water to run off.

EC 0.8-1.4, pH 5.6-6.3.

The plants recovered immensly after pH = 5.8 and grew almost 2 feet. However now Im seeing browning/yellowing on the leaf parts closest to the stem:
