Clone c-2 is from a different mother but the same strain (PP). c-2 is a much more squat plant. It doesn't seem to have the same spots but it has a different sort of pattern. the older leaves look textbook healthy but the new leaves are sooooo blotchy.
Potassium is locked out, likely by.... low pH!
Check and adjust if needed. Try foliar feeding to keep it from getting worse while you fix the soil situation. Use a complete grow fert with K and micros, mixed up kinda weak, like 1/4 what the bottle says.
Hey Wobster.....i am no pro, but i think you should put something under those pot....it is winter and floor can be pretty cold....and the roots don't like cold...and this can cause some strange symptoms... use some styrofoam or some old newspapers or what you like....it costs nothing...
well anyway nice work so far....:thumbsup:
Thanks again people. I'll see if I can sort it out with this info. Cheers Zeb, I lifted the plants out of my grow cabinet to take the pics so normally they are elevated and in a nice warm room :D
Hi peeps.
The plants are showing the same symptoms. The other day I refilled my water bottle for my plants. I Ph'd the water down using vinegar to about 6.7. I watered the plants. A few days later I decided to check the water again with my test kit. The ph of the water had gone back up to about ph 7.1. :wtf:
I made a jug of water and put a little vinegar in. I mixed it thoroughly. I tested the water and it came in at about 6.4. The liquid in the test tube was light green. I shook it vigorously for a few seconds and the liquid had gone from light green (6.4) to pale blue 6.9.
Which reading do I trust?
How long does it take for the neutralization to complete?
It feels like I'm on the edge of solving this problem.
I know it's ph...
Use proper pH down, Nitric or Phosphoric acid. Acetic and other organic acids aren't necessarily going to hold your pH stable in and aqueous solution in the presence of other compounds.
When you shake it you are allowing whatever is in the atmosphere to react with the contents of the liquid. Trust the first reading. I hope you are cleaning out the test tube (rinse 3x and then pre-rinse with the liquid to be tested) between readings.
