Is this nutrient burn?

[Vegasbear87]

First grow. Day 39.

WW x California Snow Auto

Coco, Trio, SF2000 lights

Watering one gallon ea, half nutes.

Tips are a little burnt but I noticed the centers of some leaves turn lighter after watering.

Looks like start of nute burn, while the lightening could be magnesium or a micronutrient deficiency starting. There could be a broader off pH and/or lockout problem. But get more and better informed opinions.

If you don't get very quick resolution in this thread (or otherwise), consider submitting your problem to the 'infirmary' thread. If not, as others will surely come on and say, you need to here tell us about your grow to figure out what may be going on - need to know more (or all) about media, lights, feeding, etc.

How close are those lights? Tops look a bit cooked, and/or you have a micronute defc. starting... Most of those are immobile within the plants, can't be moved from established tissues to new growth where it's needed, so they tend to show on tops first and worst.... Check the soil pH and be sure that's not too alkaline, (unlikely), otherwise you may have some of that nute burn also messing with the uptake of some micronutes....

18" from the canopy. Seems to be better this morning. I think I'm just kind of playing at the edge of it so I reduced nutrients slightly.
