I don't think this is nute burn...So I thought I had a case of mild nute burn but I haven't given the plants any Bloom or Calmag since last Friday, only water so I'm wondering if this is a nute burn issue now. Could it be my PH? Last I tested my run off it was at about 6.65. What's causing this?3 years ago

Brown burnt tips on smallest leavesToday I noticed that smallest leaves are getting brown tips. Yesterday I sprayed her with diy insecticide against thrips(soap, alcohol and h2o2). Could it be light burn or nutrient burn? She grows in bio bizz all mix which is heavy fertilized, and gets no extra nutrients.Week 3

Mosaic pale discolouration of older leavesHey fellow growers. It is day 16 since sprouting. The development looks good, but I see discolouration of older leaves. I researched a bit, and it seems to be thrips? I searched really good but I cannot spot any insects. What do you think? Preventively use insecticide or wait?Week 3

White/Yellow snipes on leaves? (13th day of growth from seed)I noticed a huge change in my plant leaves in less than 24 hours. The leaves look like they are getting burned out. What is happening? I'm uploading pictures to see the problem and also the growth conditions.
I'm watering once every 1 or 2 days (PH = 6.0). Not using nutrients yetLeaves. Veins - yellow between

Yellowing/purpling leaf tips outdoorsIm experiencing yellowing/purpling on upper canopy leaftips of my outdoor organic cannabis plant in week 2 flower. I'm feeding via compost+dry amendments so over/underfeeding is unlikely. What might be the cause? nutrient lockout? Relatively low temperature (57-75F)? pests?Week 10
