Hey bro, sorry some of these forums seem dead. I was hoping for an expert to be here myself buy there is only me

I need to know what your growing medium is. I ask, b/c sometimes if the soil is too "hot" with nutrients such as Fox Farms Ocean Forest there tends to be some light nutrient burn on the first leaves. Here's teh thing about diagnosing your weed plant, fyi. There is Mobile nutrients and Immobile nutrients. Mobile means that symptoms start at the BOTTOM, while immobile starts at the TOP. Looking at your pic, everything else seems healthy it's just the very tippy tips which as of right NOW you shouldn't worry too much about if your CONDITIONS are correct I.E good ventilation, good lighting, good soil. If you have these 3 things then my best guess would be this is a nutrient rich soil and they got a tad burned by it. That medium lokos a tad barky though. what are you using? You really need to make your own soil or go with a trusted bag like Pro-Mix, Fox Farms or Roots ORganic. They're all good shit and should get you close to flower with zero nutes. I hope this somewhat helps?
