thanks so much for all of your responses!
heres some pictures of the
Chemdog that im running along side these trainwrecks with the same nutes. they were sleeping.a few of the trainwreck in the initial pics are a week behind, but still really stunted. last night i transplanted some of the bigger chemdawgs and a few trainwrecks that seemed like the roots mass warranted it into fresh sunshine mix. i highered the e.c. on watering in on some to 1.2 (plus a full 10mls per gal of cal/mag - with kid twists advice), and little kelp. with a few others i just watered in with 6.3 phd water. just to see i guess. overnuting? undernuting? lock out? not enough cal mag? i really appreciate all your advice. its really so helpful and im really grateful for your time.
also,if your not allowing for at least 10 percent run-off youll def have all kinds of lockout/nutrient deficiencies.SOILESS especially peat/pro mix products hold nutes well.GOOD runoff is essential as well as nutrient timing freqency/strength too much too often is no good.
eyes- im using ro. the ppm is under 75 coming out. have read so many ph suggestions for the soils peat. been just going from 6.0 to 6.5, but never higher than that. you think i should give it a try? have def. been water feed water in an attempt to not let salts build up. at the suggested dosage of dyna grow the e.c. is about 400, jacks is 800. wasn't sure about listening to bottles or using a more scheduled ec chart for weed. like wk 3- .8 ec, wk 4 - 1.0e.c. or whatever. i also really have done the 10percent runoff thing. obviously my frequency/strenght and reading the plants is way off. thanks for your help.
<Sea high fives Greengenes> Pretty much how I'm viewing it, though I don't see the overwater problem you're seeing. Definitely burned from too much food.
I've never used Sunshine Mix and I don't know what's in it, but I believe it's one of those soilless media that will perform better if you treat it more like coco than soil. Now, look at this:

seamaiden. hi. thanks for chiming in! when it first started happening (pics one and two) i definitely had it attributed to overfert and lockout maybe so i flushed. got the medium down and ph set right and started feeding 1/4 strength. in the next pics , after i picked off bad leaves, you can see its progression again. i kind of thought i was initially overwatering leading to some poor uptake and deficiencies, but after the flush, i definitely let em dry out pretty well and it happened again. yeah ive read up on the sunshine mix and have been trying to treat it sort of like passive hydroponics. thanks for the link. i actually read the a while back when i started using the mix, but its good to be reminded and read it again. it and was truly helpful then and now. one of the better one on that mix from people using for sure.
on the chemdog pics the new growth looks fine look at the smaller leaves that are just starting to come through. there is no burnt tips on the new growth and the stems are nice and green. are you feeding at a 3.0 EC? or is that what the run off is?
sharl here is some of you pics blown up, the new growth looks to be coming in quite nice, keep up with the
cal-mag as chemdog needs it or her stems go purple and her leaves start to yellow with the green veins. Also i think the EC of the soil will go down in a bit. this happens to me with
foxfarm sometimes after the 1st couple watering's then it gets normal. if the brunt bothers you just alot or you want to monitor if there is new burning cut the leaf in half that is burnt.
kid twist-hi again. those are trainwrecks. heres the
Chemdog pics though. totally different outcome, but still some concerning streaks and purpling. the e.c. runoff was 3.0. im only going in at .8 or so (what the nutes come out to after mixing per instructions on bottles). yeah i guess i did notice that with the more vigorous ones in the same soil, same sized pots that the ec did go down when measuring their runoff. thanks for blowing those up. yeah the new grows always looks good and then when they're one leaf set under that it happens. is that then considered old growth and a mobile element problem? wasn't sure about that one. at first i was trying to just let the leaves fall off, figuring it'd be less stress than picking off and that if she was using the leaf as a source to draw elements from that id let use it all up or something. don't know if thats really how it works though. just trippin i guess
thanks for the advice on how to reply. that'll make it better for sure.
I recognize those leaves tell me, are there any bugs in your medium, little crawlies, or any flying gnats?
cemsgirl - thanks for your input. you know, last run and with this issue now, i read all bout the root aphids dirt mites ect. last time i had a similar issue, but was in 6 inch rockwool cubes and had some root rot, leaf death. similar looking. i checked out bout the root aphids and looked and looked with the scope. saw maybe one thing that could maybe been a sign of the aphids on the yellow sticky card. so so tiny. like a speck of dust, but so so ugly in the scope. i treated em(tree and shrub).blasted em, h202 em, and they did perk up, but i couldn't tell if it was that i fixed root rot that i actually caused by overwatering in the first place or they healed up by killing the aphids and the fungus gnats. i still don't know if i actually had em or not. aint i supposed to be able to see em on the roots with the scope at least? oh yeah, been checking out the medium now for them aphids, fungus gnats and larvae too and giving them some go nats every once in while. got the yellow cards out too. seems okay on that front.
