Might be a calcium deficiency. I would give her a water with the ol' Cal-Mag Plus or calcium nitrate. Peppers love calcium, especially during fruit set and growth.
Flushing the containers very well with water is an option. Maybe 4 or 5 times the volume of the containers. The nuclear option is to pull them, thoroughly rinse the roots, and replant in new soil. Another option is to not fertilize for a while but continue regular watering and hope they pull...
Foliar applications work well whenever the leaf stomata are open. For me that means late evening and early morning. I have done foliar feeds of epsom salt at 1 tablespoon per gallon (or less than one teaspoon in a quart spray bottle) and had good results. Epsom salts are highly water soluble...
Let us know what your watering schedule looks like. Any more than about once per week with very small seedlings in Solo cups is probably too much. Try letting the soil get quite dry between waterings.
I appreciate you looking into it. I have been curious about strong vs. weak and granular vs. liquid for a few years. Hopefully next year I can systematically test these parameters.
Thanks for this guide. Can you dive into different fertilizer schedules for seedlings, adolescents, and adults? Or perhaps talk about granular vs. liquid, and strong (e.g. 10-52-10) vs. weak (e.g. 3-5-2) fertilizers? Thanks!
I have been thinking for the past few days about the amount of time it would take for significant salt build-up to occur in potting soil due to fertilizing. Reason being, I was thinking about using less water this year. Instead of flood watering until a significant amount runs out, I thought to...
Living down here in the Tampa Bay area of Florida means dealing with frequent heavy rainstorms from now until September or even October. The potting soil I mixed up this year holds water much longer than my mix from last year. I am concerned that the root zone will never really get a chance to...
Mycorrhizal fungi promote roots. For floweing time, check out any liquid fertilizer that has an NPK ratio that is slightly higher in the P and K than the N and feed with that in a few months. I prefer the combination of Botanicare Pro Bloom and Cal-Mag Plus, but everyone has their own preference.
When grass clippings are blown into ponds here in Florida, algae will bloom within 24 hours on sunny days. A blend sounds like an excellent idea, though you have to be careful that you know exactly what has been sprayed/spread in the grass before using it.
Spread them as equidistant as possible from each other. That way the roots are far less likely to tangle badly enough to cause problems separating them.
