I am currently growing 5 white widows.
2 of them are not doing as well as the others. The 2 that aren’t doing as well do not seem to be using up the water as fast as the others. The pots still feel heavy after 6 days. When I watered them the last time I watered until it started coming out the bottom of the container.
I’m not sure what to do to get these plants back up to snuff. I was told I need to lower the Ph in my medium using ph water. The tap water I am using ph around 7.0. With the run off around 6.5. I safe In assuming my root zone would be around 6.3 or so?
I’m new to growing. Last year I used the same set up and had no issues but this year I am having issues.
You’re correct, pH is likely a big contributing factor in your issue, a soilless mix needs a pH of 5.8, I believe when you make this correction, all other things being in line, you’ll see Improvement, good luck!
Should I flush my plants with PH’d water or should I just water them normal with PH’d water?
A few of my other plants are getting big and I want to switch over to flowering soon but need to get this issue straightened out before I do that.
I’ve never flushed my plants before and would prefer not to have to but ultimately if that’s what has to be done the that is what I will do.
Last year I didn’t have any issues and only used one of the metal probe meters to check my medium and with those style probes not being as accurate maybe I just got lucky and the PH in my water and soil last year was closer to where it needed to be.
That’s what I was leaning to but thought it wouldn’t hurt to get another opinion from growers who have been through it before.
There are some holes in the bottom of the buckets. I also put a few on the sides of the buckets towards the bottom to help with drainage.
Actually last night I was checking hem out lifting the pots to check how much water was still in and they are getting closer to another water session. When I lifted them up I checked to see if I had enough drainage holes and noticed I have some roots growing out the drainage holes. (See pics)
From what I’ve read these roots will air prune themselves. So it is looking like I have good root growth at least.
Yep they are fine. There is a post on here somewhere… I think @BobWags and there are some good pics of what the holes should look like in a 5 gallon. Bucket… However don’t put anymore holes in yours as you could damage some roots.
Sounds like they’re OK for now. I will try and link in the pics Im talking about just for reference.
Interesting. I wouldn’t have even thought of putting the holes up the side in that type of pattern but it makes sense.
Before my next grow I will be sure to add some more holes in my buckets adding additional holes to the bottom and additional holes up the sides in a pattern like in the pics in that post.
I have a total of 5 plants 2 of them seem to be doing better than the others. Though all of them seem to have the PH issue. I’m just waiting for all of them to dry out a bit more before I water again. Should be ready for watering tomorrow I hope anyway.
I ordered a PH pen and that should be here today. I already have the PH test kit with the drops but want to get a more accurate reading of the water I putting in to be sure I’m right where I want to be.
Hoping dropping the PH down will take care of
My issues as 2 of my plants are getting big and
I want to get them switched over to flowering but want to get the PH in the right spot before I do so.
Thanks again for your help. I’ll try and update as I move forward.
I don’t know? I just sort of figured they could be re-used after cleaning them out and hanging them out in the sun to dry up any leftover roots and then just crumble up the roots and use it again? Hadn’t really even thought about it, but I’m not a throw away kinda guy…
This is my first time using them but I’m sure someone can answer that.
I watered them today with PH balanced water of 5.8
I measured the runoff and they range between 6.0 and 6.3.
My PH pen arrived yesterday so I used that to determine the PH of my water and runoff.
Last time I checked my water with the drops and thought it was around 7.0 but come to find out my water was more towards 7.8 - 8.0 so I’m pretty sure my problems will be solved after a few waterings with lower PH water.
