Thanks for the responses! I started these from seed about 2 months ago. Thanks for the deficiency charts. They will definitely come in handy! I live in the middle of Kansas in zone 6b. They are kept upstairs by the south facing windows. I supplement lighting due to trees the block the evening sunlight. They're nice and warm, it stays at 72 degrees or higher upstairs. I've watered them as little as possible, letting the soil dry a couple inches before watering again. They've had no fertilizer yet. The only thing I've added to the soil was a little mycorrhizal fungi when I transplanted to larger pots. When should I start fertilizing? Any suggestions on NPK ratios or brands that has been successful for some of you in the past. Any further feedback would be very helpful. Thanks again everyone!
