Lockout? IDK Yellow leaves and cupping down

[greenwithenvy]

I moved these over from the veg room 17 days ago. They stopped growing and started yellowing and some leaves were cupping down. I have a chiller in both systems and temps is 68. PH is 5.2 - 5.8. Room temp is 75-80. PPM is 600-800. I used everything I was using while they where on the veg side. They are 2 foot under the 1000hps. They were under 6 T5's. I haven't changed the light to 12n12 yet i just wanted them to get used to the 1000 before the switch and grow a couple more inches. I defoliated the day after they were put in also. Ive changed out nutes after one week. I have an RO now. Water out the tap is 180 and now its 30. Thats the only difference. Not much new growth if any. Thanks for the help.

Have you added back the calcium and magnesium that you stripped out of the water when switching to RO?

Hey thanks for the quick reply. Yea I was adding cal-mag before. Should I go more than the 1 tsp per gal they ask for?

How do the roots look they look choked out

They seem ok. The white has shaded a little do to a little green fuse concentrate. That stuff makes the water brown. No slime or root particles floating around.

Imo

The shock of having there leafs removed has stalled the plants.( imex it can take 16/20 days to recover)

This has slowed down root growth,( due to removing the lower fan leafs)

which in-turn has slowed down the uptake of nutes,

The nutes that the plant has used, were to strong and this has caused the yellowing you see.

You will have also messed up the plants ability to transpire by removing so much leaf matter.

You may find that you start to get massive spikes in your PH.

Also every single strain you defoliate will respond differently than the next, this can leave you chasing your tail somewhat.

If it was my grow i would cease the removal of leafs for the time being and drop your ppm to around 450/550 ppm.

i would set the PH at 5.5/6

And back the light off as far as you can.

I would also go back to the tap water as I don't think 180ppm is that high.

I would also consider using a root stimulant like rhizotonic,and trying to get the plants in a more comfortable atmosphere,and aim for new growth in the next week to 10 days.

Personally I think its just an accumulation of things you have done.

Defoliation.
1000w light.
change to ro
fresh tank
House move.

All these things can add a little stress and I think your just starting to see them now.

Thanks bob your prolly right. I will flush for a few hours with florakleen then do a rez change like u said @ 400ppm and ph @ 5.5. Thanks again

as said ....your plants are in shock, imho mostly from going from the flouro's
to the 1000w hps, maybe some from the pruning as well

skip the florakleen, lift the light as high as you can, ppm's should be fine, make sure your PH is right .....just keep the status quo and they'll prolly come around in a week or so, they just need time to recover and adjust

i'd go back to the tap water too cuz 180 aint to bad at all, i use tap in my DWC and it's about the same 180-220ppm, my plants do great in it...but thats just my 2c

you might wanna switch the lighting to 18on 6off as well, IME they'll recover quicker that way

I already have the RO system in the room, if I have it and its free would you still keep it or go back to tap for some other reason.

greenwithenvy:

what are your room temps? high/low?
what is your relative humidity? high/low?
How much air flow do you have in that room?

Also, what were the values above in your veg area?

Room temps are 75-80 RH is low around 25-30, im not sure how to raise it. Circulation fan in the room and fan in wall feeding in air. A Stanley fan blowing air out into the chimney. Veg room has 6 4 foot t5's.

I have seen low RH cause some weird issues. My G13Kushes will claw for any type of stress, including RH outside of acceptable range. Consider getting a fogger or humidifier.

If the only difference is that you are using RO, then maybe you can use less nutrients. The N might be too high for your strain... Also, if you don't mind me asking, what strain?

This is my opinion but I NEVER defoliate, I tried it once and I yielded less. I'll prune some leaves blocking bud sites at days 21 and 42 of flower though.

I've got a humidifier, ill throw it in this weekend. Could I put it right on a bucket top? Its one that just sits in a small tub of water? I actually have 5 strains. Ice, C99, magenta99, Grape Skunk, and deep chunk uzbeki OG kush. I ran the ice in my last run. I'm still looking for the holy grail. This is my third run in RDWC. I've defoilated a lot in the past and the result has been great. I have taken every fan leaf possibe off just to see all new in two days. For now ill get the ppms down to around 4-500 and get some humdity in there.

 

[greenwithenvy]

Same as above

Same as above

So here they are. They dont look much different. I do have some new growth. But very slow and still yellow and cupping down. I put the humidifier in there but the room gets sucked out so fast it doesnt stay in there. Is there some kind of mister or something else to get humidity in the room? Im not even sure if it a humidity thing anyway. They had the same temps and RH in the veg room. The light is 4 foot away.

 

[Bob-Hope]

Imo picture 4 looks like the ph is to high( causing the twisted leaf formation),and the brown tips is due to a potassium deficiency this deficiency is caused by high ph.

Take some picture with the light of, and ill try and help some more but its very difficult to tell from them pics.

take PH and EC reading make a note what they are then take another reading 12-24 hours later does the

PH Rise and the EC/CF/PPM fall?
PH fall and the EC/CF/PPM rise?

If the PH Rise and CF/PPM fall your plants are starving
If the PH falls and CF/PPM rise your plants are over feeding.

you want to get the PH/EC/CF/PPM as stable as you can if they go one way or the other it will tell you what they need as said above = more feed or less feed the PH will tell you what way your plants are feeding.

PH fall = plants are drinking more water than than taking nutes = salt build up
PH rise = plants are taking more nutes than drinking water = less nutes.

as your plants grow they should take about the same nutes and water if they do it that will keep the PH/PPM stable if you get a rapid change with in hours you have a feeing problem to strong or to week thus reflecting the rapid PH rise or fall.

here an example
your original water as a PH of 7.8 after adding feed it drops to PH 6.2 you add 2 drops of acid and its now sitting at 5.5. what ever way the PH goes it will tell you what the plant is doing, if it goes up its stripping the buffer (feed and acid), if it goes down its drinking the water making the buffer (feed/ acid) rise because its more concentrated.

If the ppm/EC are stable or no rapid change with in 12-24 hours then its your environment thats out of wack
hope this makes sense? im fooked.

 

[greenwithenvy]

Well there definitely drinking more water than nutes. The PPM's have been going up and PH seems to go stay the same or maybe go up a little. I really need to get a good constant read PH/PPM meter. I have florakleen still should I give it a good cleaning. Im about to say fuck it and just switch to 12/12 but I dont want them to just die out and not produce anything. The flower room is my 1st system and with what i know now i would make a nice UC system instead next go around. ramble ramble ramble.

How do the roots look they look choked out

My first guess looking at them and your parameters, I bet if you tip one of the netpots sideways to dump out some hydroton you will find some rot.

here is a rotted girl, caused by having to high of wwater levels:

Any soulution to get through the next 2 months. Whats the perfect level? thanks for chiming in. Pure
