Not light stress, but the beginning of magnesium deficiency. Giving cal/mag will solve this and prevent it from getting too much worse.

YELLOWING IN DWC!
Recently a friend transplanted his Northern lights auto into a DWC set up, since then the plant has suffered severe yellowing and stunted growth. His nute feeds are optimal just as they were in his coco format and his PPM keeps decreasing. Any ideas?

How to manage a tall plant with a thick stem in week 1 of flowering?
One plant I ordered online was pre-grown. Now, it’s about 20 cm taller than my other plants. At the top, the taller plant gets more than 1000 PPFD, while the lower canopy gets about 500 PPFD. It’s currently week 1 of flowering. The stem is too thick to bend down.What would youdo?

2 plants, 2 Mars Hydro TSW 2000’s, need help with pot size/tent size configuration
My plan is to flower these 2 girls in a SCROG under 2 Mars Hydro TSW 2000s (2x300W actual). I’m debating whether to flower them in 5 gallon plastic pots in a 2x4, 10 gallon pots in a 2x4, or 10 gallon pots in a 4x4. Does more area = more yield, or am I thinking about this wrong?

Whats the issue here? Been feeding once a week but increased to twice a week thinking she was hungry. PH 6.5 water. In Pro-Mix HP Mycorrhizae which has no nutrients in it. Picked off the dead yellow leaves before I increased food.

Blätter gelb und fallen ab Blütewoche 9
Aktuell machen mir meine Pflanzen echt Sorgen, viele Blätter werden sehr schnell gelb und fallen von allein ab obwohl ich bei jedem gießen Dünge. Sollte ich noch mehr düngen und häufiger gießen? Die Buds sehen soweit gut aus nur sind bis jetzt immernoch mehr weiße Haare als Blüte

Week Three slight leaf discoloration
In week three I'm seeing some slight discoloration. Not sure if it is something I should be concerned with. Using COCO, Worm Castings, ReCharge. Watering daily to keep the amendements active. Maybe I'm watering too much? Love to hear your thoughts. Thank you and happy growing.
