Yellow leaves seedlings

blasterw32started grow question 4 years ago

Slow growth and yellow leaves. First time this happens with my seedlings. Probably something related with the new setup I'm using now: I have 2 CFL 6500K (23w each), about 5 inches away from the plants. Temperatures around 28~30 C and RH around 50~55. Medium is PROMIX seedlings.

Looks like it needs nitrogen although could be an overwatering issue. 5" seems a bit close but there's no evidence of burning so you might be good.

Looks like the soil is very light and so you need some feeding, the yellow bottom leaves are a sign of nitrogen deficiency, you need some grow nutes.

J'ai utilisé la dose recommandée, puis légèrement augmentée au second arrosage, sans amélioration. Dois-je ajouter plus d'azote ou passer au stade suivant de nutrition ?
