PH too low

[fhydro]

This morning, i notice that at least two plants had a coloration problem. No green in the center of the new bud. I checked PH, it was 4 ans EC 4 also ! I flushed the containers and i put new nutes. Do you think i should have give them just water with good PH? Or is it good now ?

I assume you ballanced the Ph with the water change?

Yes that's fine, you don't need to flush for low Ph.

Yes i put new nutes solution with good PH and EC. What do you mean by "don't need to flush for low PH"? Just that i have to balance with PH plus, something like that ? Thanks Zandor.

If your problem is just low Ph then you do not need to flush the plants to correct the problem. When there is a problem you normally flush the medium to correct the problem. When the problem is only Ph miss balance you do not need to flush to correct the problem.

Hum, on 4 skunk, 2 are still weird, the new leaves are only 3 blades, still very light green almost white, they don't produce flower since the problem anymore, nore trichs. Pic 1 shows the main cola of a 4 weeks flo skunk, very thin. Pic 2 shows a leave all curled and weird also. PH and EC are good. Pic 3 shows a neighbour, a healthy AK47 also 4 weeks flo. What can it be ? What can i do to avoid trashing them? Can i recover them ?
Thanks

fhydro my suggestion would be to flush with 7.0ph and 0ppm water(distilled or RO) and then take readings of the flush water and see what you get. If you want get a commercial flushing solution I use Botanicare's Clearex. It's basicly glucose and water. Secondly the sick plants leaves look like they are getting shiny which is a for sure indicator of overfertilization.

Also, can you tell us what type hydro system you are growing in, it would help determine if there is other problems happening. It can all be corrected it just may put you back a few days.

check out the nice shiny leaves on this guys grow.

Thanks gronnh, are you sure i've got to flush with PH7 water and not 5.8 or 6? My set up is bases on bubblers, EC 1.8. Ã? hope this will work ...

If you are having fertilizer salt build-ups then it won't take long before that flush solution's ph drops and the ppms go up. You can flush with ph adjusted water its just that the distilled or RO water gives you a starting point to see exactly how much salts got flushed from the medium. I flush mine for several hours before every other resevoir change, which is every 14 days. Haven't had any problems with doing it this way yet.

OK, thanks, i've got it. I'm doing that tomorrow at wake up. It helps me a lot.

I flushed my buckets with water of my personal spring. The spring's PH is 8.5 so i added acid to bring it to 6.5/7. Is hard water good or bad ? EC of the spring is O.4. How long must does it take to flush correctly ?
