Can anyone give me an answer as to why this one plants starting to get a yellow colour coming threw in the middle of the leaves? I don’t think it’s due to heat as the other plants are growing a nice green

Issues after first sledgehammer flush, 4 weeks
Hey guys and gals, on week 4 of this indoor, hydro grow and I just hit this plant 5 days ago with fox farms sledgehammer for its first flush. Before this, the plant was growing very well. Is this due to the flush? Should I flush in tap water before next feed? Thx for the help ^^

Small brown points on older top leaves
1 week ago she started to get small brown points on older top leaves,and I moved her away from light to exclude light burn. Now there are a lot more of them. I flushed her 5 weeks ago, now she is getting full dosage of nutes. But these points look like nutrient deficient to me.

Yellowing Leaves
I'm concerned my plant may be prematurely yellowing. I've added Cal-Mag to see if that would help with the yellowing of leaves, but the issue persists. Yellow leaves are moving progressively higher up the plant, but my other strain is not presenting same problem. (See Post)

Puntas de las hojas amarillas, otras en garra y otras quemadas, que puede ser? Las plantas están en la 5ta semanita de crecimiento y ya pase a 12/12!!
Yesterday I watered my plants with Grotek fertilizers, putting exactly what the growth chart shows, and today my plants woke up like this. I don't know if it's because of the heater in the middle or the monster grow that adds too much nitrogen. What could they have??
