Good morning RIU
It looks like my plant has started to show some signs distress. I am very confused as it looks like Mag deficiency, which would mean soil PH was too high. Yet when I PH'd the run off it was at 5.0; I used my soil PH tester and it said 7. So I am confused. If you can confirm it is a mag def then what do I do to up the soil PH, feed it again as the nutes are very acidic and the salt will make the soil more acidic? May do full str feed? Or is it something else and I need a different solution.
I put pictures of the symptoms and the PH tests and also answered some other questions below. If you need more informaiton about what was done to the plants and when they are all in my detailed grow journal, but i think pics could tell the story.
Soil Growers:
1. Are you growing from seed or clones? - Seeds
2. How old are your plants? 32 days from sprout
3. How tall are your plants? 11 inches
4. What size containers are they planted in? 3 gallon smart pot
5. What is your soil mix? FFOF
6. How often do you water and what type of water do you use? Water when needed... I use the lift method to know when i need to water. I used filtered tap water PHed to 6.0
7. What is the pH of your water? 6.0
8. What kind of fertilizer do you use and what is its NPK ratio? I use fox farm trio, only fed 2 times last time was 50% strt which was 3 tea spoons of big bloom and 1 tea spoon of grow big in 1 gallon of water as per week 4 of the directions.
9. Do you foliar feed or spray your plants with anything? no, when i water with non nutes I do use watering can which does put water on the leaves. I use a funnel apparatus when I feed to reduce splash up.
10. What kind of lights do you use and how many watts combined? CFL 230watts @ 3 to 1 ratio of 2700k to 6500k
11. How close are your lights to the plants? 2 - 4 inches
12. What size is your grow space in square feet? 6.5 sq ft
13. What is the temperature and humidity in your grow space? Max 84 low 70 @ 34 to 48% humidity; but increased air flow today so should not hit 84 again, I would say max 82 at canopy. before it may have hit higher than 84 at canopy
14. What is the pH of the soil? no idea, used a soil test shows 7.0 yet PHed run off at same time and it shows 5.0 (see pic)
15. Have you noticed any insect activity in your grow space? nope
16. How much experience do you have growing? 32 days, this is my first grow
The above yellow parts of the leaf are extremely dry and brittle, as you can see in pic all the way to left one even cracked from touch. the problem is wide spread amongst the lower canopy but not prevelent amongst the upper (although few looks like starting signs).
Thanks in advance for help
