Yellow tip on new growth

[rlsachs2003]

One of my 4 plants currently growing has yellow tips on new growth. Not extremely bad just wanna correct it.

Plant is roughly month old. Growing in a soiless medium. Mix of pro mix all purpose mix with added perlite and vermiculite. Watered a day prior. With nutes. 6.2 ph with 1300ppm. Each plant received about a half gallon of water. Pot was dry. Nutes used was a teaspoonful of calimagic and teaspoon of all 3 general hydroponics flora trio per gallon. Light is a 600 watt mh at a distance of 24inches. Temperatures average around 73 with humidity around 45. Any help appreciated

I can't see the yellow tips. That is normally nute burn. You state 1300 ppm and for a plant a month old, that is far to high. Also, in future, start nutes at 1/4 listed amount and go up from there.

Yeah I use the OF Soil with General Hydroponics Flora Trio along with Cal Mag, floralicious, florablend and last 2 weeks use Kool bloom. PH 6.8 and PPM 700.
Anything over 700 PPM burned my plants.

I started out with 1/4 strength of the nutes about 2 weeks ago and started slowing going up on strength. I have watered with over 1000ppm last 3 nute feedings. I may cut back on amounts and aim for around 700 to 800 ppm
