Brown spots and leaves paling

And apart from this, that I think it was my fault, biobizz nutrients and soil didn't give me any troubles. But I'm pretty sure that their leaf coat degrades pistils. It happened before with WDH after I apply most of pistils on the top of the buds turned orange and again with NL. I freaked out because it was too hot and I applied it again and again all pistils in the top of the buds turn orange. So I think I made a point.

I think what the problem was. Murphy never gets wrong. Too much confidence on tap water pH, that never changed for 2 months (pH 8) and I didn't measure these weekend waterings, never happened before. So I found out today, the pH is less 1.5 than on Friday. So I could have gave them too acidic water on Saturday and/or Sunday since she was fine on Friday. It probably locked some nutrient intake. Tap water is now at 6.5 so most probably I wouldn't need to change anything. I've measured the washoff water as well and it was at 6/6.5, after watering today with 6.5. I'll give a day or two and see what happens and water with a pH near 7 next time to balance a little bit more. I think she needs about two weeks, maybe less to be ready. She has already some milky trichomes but way too many clear yet.

First ensure your pH is correct, if you dont track that, it's a crapshoot after that point. recent behavioru and nutrients used are factors. LoL biobizz, again! everytime like clockwork. i don't know if they provide a good source of Mg or not, or if they lock it out, or whatever the problem is.. it's consistent. if you can ensure pH an dconcentrations are bat-shit crazy, go ahead and dose with a cal-mag product. that stuff doesn't heal so fast. Mg def start weeks befoer you see it. I'd guess Mg over ca because of the interveinal chlorosis accompanying it. Ok, this is an autoflower.. i'd amend this a bit.. senescence is at play, you are likely near end... don't overreact unless cnaopy contines to be decimated. Then i'd ad a little cal-mag or Epsom salt (1g/gallon for the latter). in addition to your normal feed. But, i think if it's is 1-2 weeks from end, you typically se eleaves die off a bit.. hopefully not in the canopy so much as down below.

I always measure the pH on water, I try always to be between 6.0 and 6.5. But honestly I think I messed up one time this week. And I will measure the runoff next time. About chlorine I will do as you say. Thanks for the tips.

Not just your water that you water with btw but also measure your run off!

Have you been checking your water and soils pH level? If not it's probably way off! When using tap water let it sit out for 24 hrs so the chlorine in the water can dissipate. I'd start by checking your pH stat!!!
