TR-Did you pre-soak your media in pH corrected solution? Yes

Sorry, I dont have the EC and PPM values. First grow with that same tap water went fine.

I had some ph-issues at start and after first water change 4days ago. After the water change the growing of the leaves has stunned and they are really small. New leaf pairs are coming out at normal speed though. When I changed the water I gave them nutes by the companys chart, which is 5ml nutes to 1l of water. I also gave them Bio Bloom by the chart which is 1.5ml to 10l of water.

Could be some after effect from the ph-fluctuation? I have no glue...

Here... have some glue! :D

Yup, your pH is at a dangerously high level and if you cannot get it under control at 5.8-6.2, averaging just a hair below 6, you will see rapid deterioration of the plants.

Those are only two weeks old? Is that from seed or from once they get out of the seedling stage?

Temps of 84 deg. Far. might be a little hot.

I'm going to guess 2 weeks from transplant as clones. 84'F is fine if that's as high as it gets. It's 90+ where the worst problems begin.

Thanks for the advice. I have to check the ph more often. And yes they are ~two weeks. I put the seeds in to the system two weeks and 3days ago. And they popped out 2weeks and 1 day ago.

Duuuuude. Bad ass for from-seed plants. :thumbsup:

Thanks. Oh, and the ph-level has not gone over 6.4. and it got to 6.4 only once when I was out of town. Normally it stays between 5.5-6.2. The 7.7 in the form is the tap waters ph before I lower it. Is small/stunned leaves a normal ph problem?
