top leaf tips turning yellow

I had the same issue with my Orion, so far I suppose it was the light to blame, too strong too early, because it only appeared on the leaves closest to light and kinda went away when I raised it a couple of centimeters and dimmed down the power. I don't think it affected my plant much. I also saw such tips in some videos of professional growers, so I assume it's a common issue. Good luck growmie!

This could be from several different options. Light too strong, nutrition too strong, nutrition not enough as in NPK ratio is off. 3-1-2 is a vegging ratio.

Autos need less as a rule. Your diary looks ok. If not got one I advise to get a solution strength meter/ec/ppm/TDs. I'd just dial it back a bit At this stage you don't want more than half what the bottle says. Another thing your soil may be 'hot' and have nutrients in. I'm not familiar with your brand

Hi there. Yellowing or burnt leaf tips is nearly always down to overfeeding. Yours looks very early stage so it's good you caught it. I'm gonna have a look at your diary ibrb

Hello everyone First of all, I would like to point this out; I control the pH with the GHE drip kit and the light green corresponds to a pH of 6.5 and I always water it that way. I use Biobiz light mix and on the 13th day I gave AN sensie grow a+b with 0.33 ml. I use one handmade 240 watt and one mars hydro ts1000 150 watt as light. It stands 55 cm away from the plants. Are they stressed because of the light or why is the yellowing on the tips of the top new leaves?
