A few weeks ago after repotting into 50/50 happy frog and ocean forest all 3 plants soon began showing issues...light green new growth, clawing leaves, followed by chlorosis on lower leaves. They were angry. Did a flush and found high ppm and low ph. Called fox farms and they emailed me a procedure for a quick dirty soil ph slurry test. If you still have leftover mix I'd recommend testing to eliminate ph lockout as the culprit. 2 tests. A 1:1 and a 1:5. 1:1=1 part soil and 1 part distilled water. 1:5= 1 part soil and 5 parts distilled water. Mix well and let stand for 15 minutes. (I've heard to leave for 24 hrs but not in fox farms instructions) then test with an accurate calibrated tester. The 1:1 should read between 5.0 and 6.3. The 1:5 should read between 5.6 and 6.6. If outside these ranges they suggest making adjustments to the mix. In my case it was lime to raise ph. My 1:1 read 4.2 and don't remember what my 1:5 was but it was also low. I flushed with higher phed water till my runoff was around 6.0 and ppm below 600. (My water is 150 ppm) last input was a light dose of nutes around ph 6.6. I've since upped my feed/water ph to 6.5 and I did top dress with 1 tbsp dolomite lime spread over the next few waterings to finally equal 1 tbsp/gal of soil. Plants perked up and prayed ever since. Worth mentioning here the radical flush I suspect washed nitrogen out as over the next week or so I noticed lightening green. Upping my micro dosage over the next few feedings has reversed that issue. I've since learned that nitrogen let's go the easiest in a flush situation so timely replacement is a good idea.
