I have a few each of Big Boy, Big Beef and Red Cherry started from seed in the beginning of May. Germinated in jiffy pellets and split/transplanted twice since and now 3gal planters w/promix. They're getting to be around 3-4 feet. No plant related problems so far (a bird was kind enough to top one for me though). Started using "Neptunes Harvest" at half strength every 3 days (rather than full strength bi-weekly) when they hit 6-8 inches. They've been on 1000ppm of FF Tiger Bloom every other watering for 2 weeks (since onset of flowers).
About the Ca deficiency....I've used RO since germination with nothing but the above two ferts and haven't seen any sign of it on mine. I have CM+ on hand as I thought I would need it, but so far so good.
