Yellowing Tips - Od On The Nutes

[Magellan]

So I have one plant that has some yellowing tips (see pic below). It's a GDP clone. I transplanted it to the one gallon pot 2 weeks ago along with some other clones that are doing fine (so far). The soil is Roots 707

I have all of the clones under LED (18/6), the room is fairly warm-about 85-90 with about 65-70% humidity. I am feeding them a mix of Pro Blend Grow, along with cal/mag, vitamino and liquid karma. I have reduced the recommended dosage of each because I am blending them together. I am using tap water that sits for a few days to outgas and then after adding the nutes, correct the PH to 5.5. So am I seeing nute overdose? If so, would flushing with PH'd water correct the problem?

It also has some leaf curling occurring on a lower leaf (see pic below).

I think in soil you PH should be higher than 5.5

your correct....... nutes ppm is to high...... some people like to push your plant. and want the yellow tips.... so long as it stays just at tips.... but cut back on nutes and that yellow will go away......

Did some flushing yesterday with ph'd water. Will see if that clears it up.
