low ph, liquid lime?

i have begun using 7.5 plain r/o water once soil is mostly dry to raise soil ph to about 5.5-6.6....

i am using happy frog. i planted into some fresh outta the bag soil.. Clones in 1 inch rockwool cubes fully rooted... into the soil and gave full strength fertz and now the drainage ph is 4.0-5.0

the plants are not using much water as they are sooo small. im now worried about root rot and such... they are in 2 gallon container with about 1 gallon of soil, so one the roots fill in i can place more fresh soil underneath(interesting form of transplanting ive come up with.and this give me room to go to a 3 gallon pot, then to a 5 or 10 and then to a 20-50 if i really want to. talk about a solid root mass and big ass plant..


whoa, got off a bit on a rant there/.

The water going in was fertalized weak-ly at 1/4-1/2stength6.2-6.7... now its going in empty(fresh r/o water) at 7.5....

i have some super thrive that i have used a tiny amount on a few plants good growth results but ph is still a bit low.

These are all mothers im working with.

1. don't use RO water, it removes all your necessary minerals (calcium, iron, magnesium, potassium, etc. etc. ) ... that all has to be replaced, for healthy plants ...

2. don't use fertilizers, until after your clones are fully rooted ... also, this is where low light levels help (rooting) ...

3. throw away the damned Superthrive, that crap has killed more plants, than I can count ... anything beyond 1-2 drops per gallon, is TOO much ...

4. rockwool has to be fully treated for days, to stabilize it's pH (I don't use the stuff, just for that reason, I prefer RapidRooter bark plugs, already pH stabilized) ...

hope some of this helps, good luck ! :thumbsup:
