CalMag deficiency? Or light burn?

4 years ago

Seem to be doing well. Possibly move them outside when weather starts to warm up.

Been still flushing to lower ec (ppm), been watering with ph-adjusted RO water, with light feeding (1tsp/gal) of General Hydroponics CaliMagic to supplement the coco coir every other watering . Before I fed the left plant may be showing signs of calcium/magnesium deficiency with a faint yellowing to the top leaves. Ive beeen raising my light a few centimeters as the plants grow, we’ll see if more yellowing appears.

Left plant top view: if anyone can let me know if the yellowing on the top leaf is a concern I’d appreciate it. Very new grower.

Both plants are around 2 inches in length. While I was feeding today, Runoff ppm is high for both, so I’ll be starting to water more frequently laying off the nutes for a week. This is my first grow of anything so I’m not too concerned about yield, just that I learn.
