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

26 hour day cycle?
ever done a weird light cycle for photo plants? like 14 hours of light then 12 hours of darkness then keep repeating I know that this is longer than a normal 24hour day. 1. 12 hours of darkness is what makes weed start flower. Do weeds know days r 24hr? Can a 26hr day cycle work

78,600 lumens at canopy, ok for pre-flower and flowering?
I have recently received a lumen meter. Measuring 78,600 lumen over canopy, is that OK? For my other grow, does anyone know how many lumens seedlings need (at about 25000 now) ? I can convert from PPFD or PAR. Educate me! Thanks

Trouble with autoflower
Hey everyone, my seedstocker Critical XXL autoflower sprouted very quickly and had initial signs of fast growth. Since the leaves have become a lot more pale (week 3) to the point I’m worried. The other auto strain I started looks perfect in same conditions

Lack of or abundance of nutrients?
Shes doing really well but I noticed some of the leaves starting to get a little yellow so I stopped giving her nutrients and have just been giving her water for at least a week or two. She still acts like shes getting too much though? GDP auto x gumberry auto is the strain.
