Hey, dass die neuen Triebe in der Mitte hell werden ist normal am anfang der Blütephase, einen leichten Magnesiummangel hast du aber auch an den teilweise hellen Stellen zwischen den Blattadern
CalMag wäre eine gute Idee wenn du welches hast, Pflanzen in der späten Vegi und frühen Blütephase sind meistens sehr "hungrig" nach calcium und magnesium

Yellow Cotyledons?NLxBB was born with yellow cotyledons. The shell was stuck after sprouting so I had to help remove it. Took around 2 days before I saw them barely open with new growth. The new growth is green and seems healthy. Is there any reason why this is happening?Leaves. Color - Yellow

Iron deficiency?This A.M I treated her with a cal-mag mix due to yellow leaves. Today the leaf showing symptoms "tacoed" a little bit and the tip curled upwards. Same symptom on a few other leaves but only on the tips. Iron deficiency perhaps? PH'd soil on 3 spots: 6.6, 6.18, 6.3. What to do????Week 5

Yellow leavesmy little GG2 is starting to lose many leaves (they turn yellow and fall even before drying) while the other is not having any problems (the only difference between the two is the "aggressiveness" used in the LST)
it could be due to the flushing done (but less than 5 days ago) 🤔6y ago

I have lots of yellowing on the lower leaves of one plant. After reaserching I think it’s a nitrogen deficiency. Also today I’ve noticed lots of teeny tiny white/clear bugs! I’m super anxious about it, thinking my plants are goners. Any idea on what they are?Week 10
