Help First Time Grower. Seedling Tips Browning.

Hi there. My 8 day old seedlings are starting to brown on the tips. They are in promix hp 5 gallon pots. Not a heat issue. I have not added nutes yet. Could it be chlorine in tap water? I did not let the water sit before giving it to the plants. ph was lowered with lemon juice to about 6.
Thanks so much for the help! They are 4 different strains of autoflowers.

Usually the soil does a decent job of regulating ph on its own. You might be fine with your tap water how it is. Once you add nutrients it will probably drop on its own.

I use distilled water at a neutral 7 (with added CalMag) and by the time nutes are added I’m usually in the 6-6.6 range. Rainwater also works great and is free.
