Please help them theyre dying!

Hey smackhead,
I would look into a digital pen type unit, you should be able to find many different makers. As for which unit to buy, I always go by you get what you pay for but look around a little more and you can find it cheaper! Hope the flush helps. :thumbsup:

the GH liquid indicator is fine. Hanna meters are crappy. Truncheons are indestructible.

plants are lookin ok now, theyre hardly droopy at all, lookin a paler colour than they were, the yellows still there and before it was flushed the yellowness had spred to more plants so they looked more uniformed, theyre all sprouting a new set of top leaves which are a good shad of green,

With the flush the runoff had a 6.0 ph so i flushed it with plain water as it is out of the tap which had a ph of 7, so do you think it will even out ok?

Possibly, or it will at least help some. You can keep checking the runoff to see how well it is working. If your tap water contains a lot of CaCO3, it will work better. But the usual way to do it is with commercial 'pH up' liquid.

should i put a slight amount of ph up with the 7.0 water to bring it up to 7.2 maybe? i already bought some just in case

GREAT. Yes, 7.2 is good. Since your medium has shown a tendency to go low, bring it right up to 6.8 by flushing with water at 7.2 until the runoff reads 6.8, and then water with a 1/4 strength complete fertilizer.

do you mean 1/4 of what i was using or 1/4 of reccomended? i was using 1.5ml per litre an their site says 2-4ml per litre

1/4 of recommended. You can go a little stronger than that; it's not exact. You are just replacing the BAD stuff you washed out with GOOD stuff you want.

thanks, will do 0.75 ml per litre, ive got a few progress pics here:

also ive took one of the plants out of its pot for a minute, as you can see the roots are very visible, are they long overdue a repot? i was planning on another week or two of vegging in the same pots then switching to what i think is a gallon container when they go into flower:

Roots look right on schedule for a repot- good development, not overly rootbound.
