HiddenMessagestarted grow question a year ago
One of the plants seems to be having more trouble than other. Leafs are dryish and brittle especially where the tips have curled but doesn’t seem to be have as much new growth as wanted. Been using only Val mag for feeding. Just wanting to get them healthy before I switch flower

Cal/mag is a plant health supplement and only needed in small amounts, it is not a growing plant fertilizer.....it generally has zero N/P/K, the 3 essential macro-nutrients for sustaining plant life.
She is suffering on many levels and probably affected by calcium toxicity.
"Flushing" your soil and starting with a cannabis specific "grow" fertilizer may restore health before looking at going to the flip in a few weeks.

Huge nute burn by looks of it on top pic. It's either nute burn or light stress/burn from leds cause similar symptoms
Bottom pic looks like the start of either a zinc def, copper def or again light stress/burn.
Guessing you have Leds as there doesn't look to be any heat stress present, I think your lights could be too close....would be odd to have nute burn on one and then a def on the other 🤔
