hi I hope some one can help me I been trying to fix this problem on my strawberry sour d for a month now I have dark purple stems and yellow tips with brown spots and leaves changing color to more of a dark green blue I thought it had a phosphorus def with maybe another but I flushed my 3.5 gal air pot with 6 gals of light nute solution water the runoff tds was around 1000 and I'm using fox farm soil the ph run off was at first at 5.5 but now have it at 6.35 by adding sum garden lime I'm using technaflora recipe for success for right now this plant is 2 months old. I been growing for years and usually don't have probs but just switched to soil from hydro and can't seem to shake these probs plz help p.s I did take off 2 branches about 4 days ago I don't know if the stress could have sumthing to do with it thanks for the help.
