Grow Mediums Help: Flushing with autopots

[lunarman]

This is not a should I flush or not debate to improve taste etc.

I thought that I could just switch my res to water and that would be like a flush autopots style. I used PH'd water in my res for 4 plants for about 8 days to do the flush. And the plants looked like shit after. I have since been told that is not a flush. Its just bottom feeding using water. A flush means remove pots from the trays and run water thru to runoff and let that drain off don't let the pots sit in the runoff.

When you look at the pictures here I think there are two things going on. One is some crisp tops from an 600w HPS light that was over these plants. And some early yellowing from light stress I think. Not just natural fading later in flower. The other is someone told me it looks like nute lockout too. This is day 80 BTW. Now when I properly flushed one of these two MG Orange Diesels runoff EC was 3.3 or something crazy. So my theory is nutes were locked out probably from bottom feeding water and the nutes just built up in the coco and then the "proper" flush released them. The other OD had an EC of 1.3 when I measured the runoff so that one might not have locked out. I'm just pulling theories out of thin air really. Would be interested in what others think. I really don't want to have this happen again after the plants had such a great grow. Its a heart ache to see this at the end of a grow. I should also mention the flowering was great on these plants up until about 2 weeks ago when everything started to get too yellow. Also the trichs are about 50% cloudy. I can not get these plants to ripen the trichs any further. I know I have to cut my losses. But I'd like to not have this happen again. I'm thinking of bailing on autopots now as I had one plant in this run that was handled manually (Sweet Nurse CBD) that looks so much better than the ones in the autopots right now.

hi pal im on my around 6th run with autopots and to flush them i would do the same just ph water in my res for around 5 days id normally go for and in that time you will get lots of yellowing going on its like 5 days with no feed them leaves are going to lose all the green it wont affect your buds though also if you were getting a ec of 3.3 you have had massive lockout and maybe your issues have just all hit you at once if you were seeing yellowing just before you put them on water ..if it was me and they were 50 pcent cloudy id start chopping them also if you go in my sanlight thread you will see i had some root issues with one of my girls and she yellowed up and that caused a lockout ive got her back on track now

I always flush my plants like you dude im on day 5 now and there still very green (been using autopots for about two years) some times I ph the water sometimes I don't if you think its a build up of nutes just water at about ph 7 (my tap water is ph 7) that will lock out all the nutes and make your plant use up whats in the leaves oh I think @pop22 doesn't flushes at all its all in the cure

I never flush personally but considering your situation it will not hurt them in my opinion. How do the trichomes look?

It's lockout from bottom feeding water bro. You don't have to give up on Autopots, but if you are using Coco I don't suggest bottom flushing/feeding just water. Your Coco has built up nutes in it from bottom feeding for 2+ months. You can say "So and So just bottom flushes his plants, and they don't do that", but that is lockout and it is caused by bottom feeding/flushing plain water. Chop that crispy critter and move on.

Absolutely a chance the same thing going on with @lunarman. I would guess his root system compromised. Also, you are adjusting the flush water. Sometimes plain water doesn't hold a pH adjustment, so make sure you check your Rez water if you are doing it that way. Possibly could be too high

If there is a salt build up, its from over feeding. I'm growing in the same soil over and over, sort of no till. I cut out the stump of the last plant, then plant in the hole. i ever flush and these plant are the 7th run in the soil.

Flushing, for this situation is likely a waste of time and water but if your going to, take the pot out, put it in your tub and run 5 gallons of water thruogh the pot. Let it drain and put it back in the base. Hope for the best.

And Flushing at the end of a grow is a busted myth, and contrary to science. There's a thread here on AFN on the subject.

He is using Coco, not soil. Coco holds onto salts and reacts differently plain water feeding than Soil. And I agree fully that it is a waste of time to do anything at this point. Flushing is not a Myth, it's a preference. I like my plants to fade a little and they won't fade much or at all if you keep feeding full strength in Coco. I have grown Thousands of plants in Coco. Some yellow faster than others. Some would stay too green for my liking without a flush. If you have a plant that the Trichomes say almost done, but the leaves are green a little flushing will speed up the process. You can see the EC drop while Flushing Coco in your run off after a couple of days.

Btw, That is flushing from top. Bottom feeding straight water and causing lockout is worse than not flushing. I would rather not flush and keep feeding til I chopped vs bottom feed straight water.
