Please fill out the infirmary sheet, we need more info to help you. Do that and I should be able to pin point your prob, I grow RDWC to

Edit:good call orpanic, I was guessing PH lockout but wasn't going to jump the gun b4 he/she filled out the sheet

Oh yeah sorry PH is 5.5 but keeps going up to 6.0 after a day so i PH- every couple days
well i thought that but i gathered my PH is in range for manganese def.
They only thing i have done is dropped my grow and just using bloom and micro

Sorry mate ok i will find the sheet and fill it out i'm just busy in the lab but i just tried to be sneaky lol
Thanks

Ok, in RDWC it works like this:

You start with your nute mix

If the next day your PPM is up and PH is down, you are feeding to high

If the next day your PPM is down and PH is up, your feeding to low

Dial them in According to your information sounds like you could be underfeeeding. If I am "riding the drift" I like to start at 6.2/6.1 range, and catch it at 5.5/5.6 and bring her back up. Never had a probelm with PH going up lol

More information always helps, but seems like you need to feed them more, and also try to maintain a 5.8 PH allowing some drift each way.

I cant seem to find that template!!

My ppm well e.c i'm going by is 2.0 then i drop it down with plain water so i've basically overfed them even though i thought i was being quite reserved.

I know man the PH going up is really doing my nut in, it's not right my PH drops always.
I'm thinking to flush and start again but only changed res on monday.

Promise i will post more detail and a few more pics thanks guys

yea 2.0 isnt to bad for 4th week, unless shes sensitive. I run 1.8-2.0 around that time.

Edit:2.0 not 2.5 lol

Potassium deficiency/overwatered combination would be a guess.

Mn would be leaves near the top of the plant, potassium would be the leaves at the bottom.

Hey thanks for the feedback, i managed to get right in and check the roots on the sick plant and when i drained it i touched the rootball and it just came right off!
So basically cleaned off any dead matter with my hands the dead stuff came right off,
then i added some Pythoff to the system and put some in a bottle and sprayed the roots and will do so daily from now on

Thanks

yeah, overwatered will mimic as pyth root rot because it's actually the overwatering that causes the the pyth so it's hard to tease apart sometimes.

There are many challanges in growing that present itself like this where it's hard to tease apart one problem from the other as the two problems are so intertwined.
