BioBizz 
LST 
Hey 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? 
She has droopy leaves. There are leaves with brown places, and some leaves in the middle of canopy turned yellow. At last she started preflower in week 8(auto) but compared to another girls she is very slow with pistils. Some leaves are curling up.Maybe too much light? 
Almost all new leaves are extremely thin on base. On some nodes only 1 finger is developed. Some new leaves curl down like claws. I suppose these leaves developed from baby leaves burned by alcohol spray week ago. But maybe it is smthg else? Should I maybe cut them off? 
Today 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. 
1 week ago she started to get small brown points on older top leaves,and I moved her away from light to exclude light burn. Now there are a lot more of them. I flushed her 5 weeks ago, now she is getting full dosage of nutes. But these points look like nutrient deficient to me.
