Yellowing older leaves
Flaviostarted grow question 6y ago
Is this a nitrogen deficiency? It's happening just on the 3 bladed leaves of the plant on the left. The plants look overall healthy, at least I think

I have about 3 weeks left of flower, haven’t started flushing and had some deficiency in the beginning. The yellowing is starting to creep up to the smaller, upper leaves. I’m thinking a cal mag issue since I have not supplemented with that at all. Is it too late to give ?Week 7

Idk what went wrongMy Special Kush 1 is on week 5 of flowering. 4 days ago bottom leaves started yellowing, yesterday i watered and checked runoff ppm, which was 5000! So i decided to flush. Kept watering with tap water (PH 6.8 ppm 300) until my runoff water was 600 ppm. What your opinion about it?

Deficiency?Hi, I've encountered some deficiencies in my plant but I'm not sure whether it's Magnesium, Potassium or anything else. I'm using the BioBizz outdoor trypack (BioBloom+FishMix+TopMax) Currently 2ml/L each. Symptoms are shown in the lower leaves. Maybe CalMag? or Pk 13-14? pls lmk

Potassium deficiency?Shes got about 2.5 weeks left, at first I thought the leaf discolouration was natural as harvest approaches but the necrosis has me worried. My guess is K deficiency. I was about to start flushing, will she make it to the finish line ok or should I attempt to fix this issue?

Magnesium or Nutrient Burn or?Magnesium deficiency, or nutrient burn or??? Only on the lower leaves so far, curling down was existing genetics - but the burnt tips are new and some have even curled up now. Probably 5+ weeks left so too early for natural dying off?

Weak yellowing leavesNot every single time but quite often my plants are turning yellow in the middle of flowering. It starts from bottom and follows to top. I can basically “take off” leaves off stem and the upper ones getting dry and brittle. I’m also quite sure the ph level is correct. Any guess?
