Potrebbe essere colpa delle luci . A quanta distanza stanno? Se non è per quello prova ad innaffiare e misura i ppm dell' acqua di scarto se e superiore a 8000 e' un blocco di nutrienti .

Possible deficiency/humidity/pH problemI've been struggling with same problem from beginning of grow - leaves having these dry yellow/white spots. The first week I used too high pH which later I replaced by rainwater - new leaves were healthy, but last night I left tent at 70% RH. Somehow it returned - still rainwaterLeaves. Tips - Burnt

My leaves head upwards, is it a bad sign? [Autoflowering]First time I get this far, I sometimes noticed after I water the leaves start to head upwards, or even without reason during the day.... then go down again.
What is the reason for this you think? Is my light too far? or not enough something? I only watered twice in 10 days.Week 2

Nutrient burn or under watering?several leaves getting yellow at the tips. have not made any major changes to the environment in over 2 weeks. Water ph is 6.3. I am leaning towards under watering since the bigger of the 2 seems more affected. How would a more experienced grower proceed?Week 4

Crispy leaves?Crispy leaves developing as it flowers. Seems to just be those that had some spots from what appeared to be a magnesium deficiency. I hit it with cal-mag and the spots stopped but recently the most affected leaves are shrivelled. Only maybe 4-6 leaves right now.5y 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

Fixing Nutrient Burn with Coco in High Frequency FertigationHigh Frequency Fertigation in Coco, nutrient burn issue. I know I have to be careful w/ diluting substrate. Do I also need to always include some type of Cal Mag in my water, even if just topping off reservoir.
