Lol sorry D, I was skimming responses for runoff and missed the slurry test. Thanks for sharing the method. Everyone else has detention for 15 mins after school.
The way to look for BM without a scope is the pistils. They will eat them. If you have pistils you don't have mites. If your pistils are brown and dead but still present, you don't have mites.
Using the same ratios, I usually go 1.6 EC into flower, going as high as 1.8-2.0 at key times. Never have seen any indications of over feeding.Anything under T5 normally looks pretty good. I am however now experiencing issues there too after replacing all of my lamps to brand new. I was running on 3-4 lamps as the others had died. Replaced all 8 of them and now I'm getting some deficiency almost immediately? Calcium Def?
Granted these have been in solo cups for way to long...they are not allowed to dry out.. They are hit daily with 1.2EC jacks until run-off. They are going to be re-homed to a friend as soon as he gets re-setup which is why I havnt potted them into larger containers yet.
Mom's are staying healthy off to the side of the T5. I turn on a little LED light from time to time to keep them happy.

Clones in solo cups too long now showing Ca- (the orange marks on leaves?) as well as Mg- (the purple petioles and canoe/cupping of leaves?). These plants were literally beautiful 3 days ago before the lamp increase and change.

Am I merely just feeding too weak with the additional light? I normally strictly fed 1.2 EC Jacks + CalNit, but I have tried a few waterings w/ epsom before my CalNit at the rate of .8g / Gal. No change noticed in any of my gardens.
Thanks for all of the advice and kind words.
Been away for the last 48 hours so haven't done much in way of changing things.
What I did have time to do:
- Dropped my blumat res to 5.3 pH, it's reading 5.7 the following morning/current. Planning to drench them with a mix of this lower pH, but for now i've only had time to allow the blumats to do their thing.
Try keeping your ph between 5.5-6, ideally it should be allowed to float through this range (i.e start at 5.5 and allow it to drift upward to 6.0 before adjusting to 5.5 again.) I wouldn't bother with the drench as your ph is close to fine already. If your water is too stable to drift much, aim to stay right at/around 5.8 ph.
- Did a slurry test out of one of my uglier vertical plants. I just dug down a solid scoop of coco and combined it with my RO water (same size scoop). Slurry measured out at exactly 6.0 pH, however it had a EC of 0.8. (while being fed 1.2 - 1.3 EC). Does this indicate that I am in fact feeding too weak for my conditions or opposite since it was mixed with an equal volume of RO water?
Yup, you need to bump up the feed is exactly what that's telling you. Mixing media and RO/distilled water in a 1 to 1 ratio gives you the most accurate picture of what your media is actually seeing. In this case your media is 0.8EC and ph of 6. Bump feed to 1.5EC and see if that doesn't solve your issues
- Scoped my leaves with a 60x scope, but didnt see anything. Checked around for a while and pretty confident I'm not seeing anything on the leaves.... at least not with a 60x. I am however seeing some very very tiny white pests in my coco. You'll see them with the naked eye only after brushing some coco around.... scrambling to take cover. They are white, very tiny, and resemble something much like a spider mite.
I don't have fungus gnats, nor havnt for a long long time. I see no other sign of visible pests, and have pulled relatively success crops having noticed them before. Are they the source of my problem, or merely a harmless soil mite? No flyers ever seen, nor any carcass or pests discovered in previous root balls.
Still pretty stumped. Tomorrow I'm going to try and hand drench everything good with a slightly higher EC (1.5 - 1.6 EC) / lower pH.
Yesterday my sealed space was running around 78F , 60% RH. Current readings are same temp, but RH is 45%. I realize the RH could optimally be a bit higher, but certainly 40-60% shouldnt be any source of my troubles here, should it?
Are you diluting the calcinit into water before adding it to your rez? If you re adding the powder directly into the res, sure chance of precipitation.
Another issue is that in coco you want to feed less potassium, and jacks has quite a bit. Too much potassium will lock out calcium, giving the symptoms you are seeing. As the plant is older this gets worse and worse as K keeps building up in the medium. I would flush them with plain 6.0 water and then feed them 1.2 again and see what happens. Sorry but you would have to switch nutrients to get around this issue, or perhaps cut back on the jacks hydro during veg (go equal parts jacks:calcinit instead of normal 3:2 ratio for hydro).
But it could also be the crawlies - could be beneficial soil insects you see or something nasty like root aphids. In any case I would hit them with some bayer complete in early veg from now on to get that out of the way before you go into flowering.
Just wondering if you ever got this taken care of FF?
Heres a little story;
My girls were vegging at a homies house while i got my rooms built, wired etc.
They were sitting in his garage under 4000W of HPS... No climate control, no intake, no exhaust, just a lighting controller, 4 ballasts and a garage. 24 hours of light per day
When i first took them over as clones, they were looking fine. After repot to 5 gallon containers they looked like shit for almost 2 weeks. then they took off for 4-6 weeks and actually grew to be pretty sexy bushes..
Then it got cold. REALLY cold. Even with the 4 lights- no insulation in the garage- it got cold in there. the plants started to get really droopy(looking like your pics)..(almost exactly like your pics)..
I finally had enough, and went and picked my girls up before my room was ready b/c i knew that even a half finished veg room is better than a 40 degree garage..
Anywho, after i took them home, they developed a shit done of deficiencies, (some bluish/purple leaves which i have never seen before), etc.
Im almost positive it was the cold---made it impossible for them to eat because they were just too cold...
Anyways, got the bitches home, gave them a nice flush, and then started back on the 1.2 jacks diet..
After 3 days, i checked my runoff - PH 6.4, ppm 220...
A little high, and a little low - Slurry test time ---
ph 5.9, ppm 200..
Perfect - Little low
So I upped jacks to 1.5 ec, and we'll see how they respond. I'll post pics in this thread in a day or two.
Just hoping for an update from you
Just helped a friend with the same problem actually. The cold prevented the roots from uptaking nutes and as a result nute buildup caused lockout. Just had to flush well, then and start feeding at 1.5EC to compensate for the CEC disruption. Probably take a week for them to completely bounce back, but you'll be just fine.
The same juice is being fed my horizontal room. It got in a minor slump initially aftering seeing the HPS and some orange markings on the leaves, but seems to have bounced out of it going into flower. These were flipped a few days before my vertical room.
Getting some slight twist and a few orange markings near the leaf tips, but looking a lot better over here. I can't tell if this is worsening or if I'm in the clear. I think it still might be slowly showing up. Fed until run-off here, but looking to get the blumats rolling over the next day or so.
