Les feuilles de la Master Kush s'éclaircissent sur les bords, est-ce bien un manque d'oligo-éléments ?

Could be a copper deficiency. Very slim chance it's Tobacco Mosaic Virus

Yellowing, curling tips?I'm in the middle of week seven and noticing significant yellowing, curling tips, especially on the top colas. Is this cause for concern and what could be causing? Feeding low-dose (1/4-1/2 tspn/gal) of dyna-gro bloom and the plant is growing in MG soil. I know, rookie mistake2y ago

Overwatered cubes in hydro? Too close to the sun? or effect of having addHi All, I have issues with my first hydro grow - i effed up. I think i was too slow in the transfer over in the tank. Light is 200 PPFD, EC at 0.6, and barely added any nutes.
Did i manage to overwater some of these plants by having them too close to the net pot?2y ago

Yellow leaves at bottom. New growth good. How she looking?Tried a new nutrient line, instant Pythian(sp?). Switched back now and she seems better. Should I be concerned at this point? New growth looks good to me. Although she seems droopy for this time of day.
My theory is that the new line was more sensitive to warmer water temps.Week 2

Underfeeding?Beginner grower here. Had some issues with underwatering and it's slowly recovering. Now am unsure if yellowing leaves are signs of underfeeding as it's still early in flower or due to the underwatering. Bottom leaves yellowing and dying off too. Using GHF Bio line as recommended3y ago
