Trouble with Calmag?

@gottagrowsometime sorry my diary is just a bit off right now, im using only one evo 3 with 25% my temps are around 18 - 22 in tent, i will get exact numbers tomorrow. Im feeding with around 500ppm except last time after putting them into the 15l pots and ph is put down to 6.3 - 6.5 before feeding after mixing it. Im using heat map Romberg SkinnyHeat 75x75cm - 95W, because its pretty cold here. And i wanted to warm the roots, maybe the are not happy with it? I will check the temp deep down tomorrow to. Thanks for all your replies @GrowingGrannie thanks for helping again nearly same question. Thanks for the link. Another thing, i think they were to long inside the little pots beacause rooting was already all over the place, lets see if they recover in the big pots with a bit more mag.

if Mg is only 11 mg/L along with the interveinal chlorosis and othe symptoms, i'd guess low Mg is the poblem.... i have hard water, so i get some from my tap, but as far as what i mix up, it is 80-85ppm Mg -- soilless context but over time will aveage out the same in soil too. And, these plants are plenty mature enough for a normal dose relative to how hot the soil is. if you fertilize every other or third irrigation, then you pobably add more at 1 time but with less frequency. the plant's gowth will require the same number of building blocks -- though growth rates may differ for various reasons.

No— looks like humidity/vpd issues coupled with watering too frequent

I c you are using 2 leds for veg. Really you only need 1 at this stage. I veg my plants with a 100watt at 25% for the 1st week or so and then move up But, one of those lights would veg size of 3x3 easily.. so I'm nearly sure the curling of the leaf is light stress. In veg very little is needed and a small light vegs 15+ of my plants for the 1st week.. r my sp3000 turned down to 25% for your whole veg period.

I can't understand your ppm. But at this stage you should be aiming for 3-400ppm.+ ambient tap ppm. So if your water is 150 you should me aiming for 600-650ppm. Also your calmag looks awful high. Check your water before hand. Anything with 250ppm ambient tap doesn't really need calmag at this early stage. So when giving cal/mag bring your water up to that 300max and increas as needed. As these 3 are soft metals and too much can be a bad thing. Also try regulate all your feeds fert/water/calmag to be in or round the same PH . She needs food. But, as I said. If your hitting said ppm up above your more likely dealing with ph imbalances. The curling up is usually Associated with heat stress from light. At this young you only need 4-600umol (ppfd) so 35-50% light power. If it was the heat in your tent.. your leafs would curl down. So I reckon its light stress. The purplish on your leafs. It's very early for that. But can happen. But as I can do light yellowing, again, I'm putting more down to lockout of certain nutrients from imbalances in PH. GOOD LUCK PAL.
