I'm running a 1200w led on 18 / 6

I don't think the light you have is powerfull enough for the space pal what is the draw from the wall of it I had 3 in your space if you can add more even cfl lights it will get you fatter buds

Advice wanted:

Well I think I figured out why my bud production has almost stopped. I tested my runoff ph today and it was 4.0 whis is also the lowest my kit reads so who knows.
I'm not sure what happened, i use only rodi water and all advanced nutreintes ph perfect. I check my water and I check it after my nutes are mixed. It's always been 6.0 - 6.2.
So I guess the soil gradually brought the ph down. What I'm wondering is what should I do? I gave all the plants a pretty thorough flush with rodi water. Should I continue that? Or maybe offset with some ph 7.0 water. Any advice is appreciated

Day two of flushing here. Tested this on the run off and it was 2600 lol. So defanitly some nute build up in the soil. Which I'm guessing lowered the ph will all the salts and in turn caused a lock out. So I'm flushing ph 7.5 through them till I see run off I like.
Another lesson learned!

What kind of ph meter are you using?

Yes it needs flushed if reading that high. How are you testing runoff?

First off opinions are like arseholes every one has one some just stink worse than others. That being said a lot on here dont agree with runoff readings. But when done correct can be very helpful.

Get a few gallons of ro water from store so you know exactly what your putting back. Which is nothing. Ro water should be 6.5 and 0ppm

Water medium slowly and evenly. Saturate enough to get some runoff.

WAIT 30 mins before next step...

Okay now go slowly water medium again, only this time put a clean catch can or bucket under pot.

Now test runoff. If its still low ph and high ppm keep adding ro water slowly until gallon is finished.

WAIT 30mins again repeat until runoff is what you want. Then keep close eye out for def. because you just flushed out everything.

Thanks. That's pretty much what I'm doing exactly. I have my own ro di unit so everything the plants have gotten since the beggining has been just ro and nutes when I added them.
I have two plants what i consider finished now. Run off down to 900ppm from 2600. Took me about an hour or plant and nearly 3 gallons of water each. I adjusted the ph of water to 7 and the run off came up a bit. It's not the ph I'm worried about as much as the overload of nute which I'm pretty sure caused the lock out.
After I'm done them all I'm gonna give them a very light feeding to replace anything I washed out completely

Others may chime in but you may still have all the plants needs still there. I wouldn't get anything until she showed something wrong. 900ppm is still high for an auto and nearing end. You will find that with autos less is more.

Okay thanks. I'll just throw in some cal mag instead of a full feeding. I'm wondering where I went wrong. Should every third or fourth feeding I substitute just ro water instead?

I have only been checking in and looking at pics, haven't seen what you were feeding. I never feed on any kind of schedule. I always just watch my babies and see what they tell me. I've been using the same dirt for 6 or 7 grows and my plants are healthy to date.

That being said my plants see more tap water than nutes. But I'm lucky with great water. Ppm of 150 and 7.5 ph after 24/48 hrs. But all my water sits for a week before I use it. I have 10 or so 1 gal jugs of water. As i use it i fill it up and put it at back of line.

I'm using advanced nutreintes a and b, overdrive and sensi cal mag. Once I started feeding at about two weeks I've been steadily feeding ever since. From now on I'll be mixing that up with ro water
