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.

Leafs losing Color, die off.I could really use some help recognizing if and which deficiencies the Super Skunk has. It's currently growing in an organic soil that's been pre-fertilized and should be enough to complete the cycle. The temperatures are around 23c (73,4F) day and 19c (66F) night.

After buying some equipment, I decided to try to germ some old, random seeds to start, and buy good feminized seeds when I have more cash. 1 female worked out, but no idea of strain or if auto or not.
