How do I read these numbers? My tomato plant watering numbers. Ec going in 321. Coming out 1206. Ppm going in 157. Coming out 591. The tomato plant has had a hard time keeping its blooms this summer. Just wondering if I am giving her enough or too much. Organic soil grow. Oh i almost forgot ph going in was 7 coming out was 7.2.
The most common cause of tomato blossom drop is temperature.2 Tomato plants can get stressed if the high daytime temperature is above 85 degrees Fahrenheit, the high nighttime temperature is above 70 degrees, or if the low nighttime temperature is below 55 degrees.
Tomatoes grow best if daytime temperatures range between 70 and 85 degrees Fahrenheit. While the plants can tolerate more extreme temperatures for short periods, several days or nights with temps outside the ideal range will cause the plant to abort fruit set and focus on survival. According to the University of Nevada Cooperative Extension, temperatures over 100 degrees sustained for four hours can cause tomato flowers to abort.
Ppm & ec meters won’t work for liquid organic fertilizer it’s partly broken down but not all the way an the meters only read what’s fully dissolved or available to the plant, what’s coming out is a decent measurement of what the plant has to eat on & with the ppm being what you said it’s at coming out it’s about perfect man,
One of tomatoes biggest enemy’s is heat, anything over 85f an the flowers will drop off it’ll do the same if it gets to cold.
