Calcium deficiency impossible to fix.I cannot get ahead of calcium deficiency in spite of adding calcium nitrate base with extra cal-mag daily. I just keeps getting worse and worse... any advice? Hydroponic RDWC, day 29 flower. It’s fine in veg, once they hit bloom, can’t keep them healthy.Week 17

Rust spots on leaves, second grow and need some confirmation.I'm noticing rust spots on my leaves, which I suspect could be due to nutrient burn or lockout, given the PPM is unusually high for this stage of growth. To tackle this, I'm planning a simple flush with some Cal-Mag, keeping the pH at 6.5. Does this sound like the right approach?Week 6

Leaf issues. Lockout? Need to Flush??Leaf issues started showing up in 2 of 3 plants, progressing fast.
Soil runoff tests have been v. high (2000ppm+) so we're assuming it's a lockout issue.
We watered 1 day ago, with 200ppm solution so pots are still very wet.
Better to let them dry out a bit or flush right away?5y ago

General feedbackAny feedback would be greatly appreciated, to me the plant looks healthy, however it is a bit small considering it’s age, right? I’m thinking it may be because of the cheap ‘300W’ light I was using at the beginning of the grow. What do you guys think? (Video end of week 6)5y ago

Outside Transplant NutritionI am going to be transplanting to an outside location. What is the opinion on needing to fertilise the soil before the transplant? I’m under the impression that if the area is littered with brambles then the soil is already ideal?Week 3

Hungry? N deficiency?So this sort of just happened overnight. Plants were very thirsty this morning and noticed a handful of leaves that are fading.
I fed them 1tbs of dr earths flower girl and 4ml of calmag in a gallon split between the 2. Should I add some of their 4-4-4 as well?Week 9

Lime green and droopySo she has been getting lighter the last couple weeks since the soil became too wet from being too deep in the aquaponic water, figure it’s ph related but I flushed her twice, each time ph came down, but didn’t seem to help, am I going the right direction or is it just N def now?Week 9

Canna flushThank you so much for the information. I have been using Plagron nutrients for a long time and have never had any major problems. OG is my first to be very sensitive. She went to sleep in the vegetation. It's not working now. Can I do a flush with Canna flush? How I use this? ThxWeek 3

Salvageable? Or pull?Well boys I done fucked up. Got a major K deficiency (since fed them). Didn't want to save them with liquid nutes as I'm trying organics. Assuming they live (I think the Bubba may have bounced back?) should I try to get a harvest or should I just pull them now? 1 week into flip.Week 9
