Hi guys. I need a little help identifying the problem here.

Growing indoor in soil with perlite. Plant is about 1 month old from seed, currently vegging under a Blackstar Ufo. Biobizz nutes, although so far i have only used fishmix in low doses N P K 5-1-4. I'm using tap water, which ought to be fine here. There's 3 other plants in the tent, and they all look fine. Unfortunately i have no way to measure PH level, but all parameters are similar to earlier grows and that has never been a problem. Temperatures and airflow are good. No bugs either. Have a look at the pics, and please let me know what you think this could be. Thanks in advance :)

What kind of soil are you using? Did you add any ph buffering amendments? How often are you watering. How often and how much nutes?

Soil is Eco Bison Terra (85% Organic soil) Ph 5.5 - 6.5 is what it says... No ph amendments. Watering when plants are thirsty, usually about every 3 days. Nutes have only been used twice at about half the recommended level. I hit with nutes every 2nd watering normally, i just waited a while to start this time. Oh, and humidity is around 50%

Looks like beginning of nute burn. Also looks like ph is probably off too. 5.5 is low for soil 6.5 is good so id def get a ph meter. Id back nutes off to 25% for a few feeds. But just use water for 2-3 times.
