Cal/mag deficiency?

Hey guys!

Running into a problem 4.5 weeks into flower. I think it is a cal/mag deficiency but wanted some thoughts on it. Grow set up goes as this.

Indoor led light
4.5 weeks flower
Fox farms ocean forest 5 gallon pots
General organics Go box nutes
Watering every two days 1/2 gal

I have tried to up my calmag with no positive results. Thinking might have an issue in my root zone or with ph. Plan to flush my next water cycle.

Thanks!

some pics in normal light would help a lot. it does look like calcium deficiency, hard to say about mag in that light.
just realize calcium deficiency doesn't necessarily mean mag deficiency...companies package it like that because it's a problem in hydro, but they're actually two separate things....
i would get a small bag of dolomite lime and top dress a handful into the soil, then water it in. Cal-mag is a decent product, but it has N, Fe,...which you probably don't need, and could cause further problems

Here is the thing with Fox Farm OF soil. I think it is excellent but it runs out of steam in flower. IMO, this soil should be mixed with Happy Frog, 1 part of each, then in your pot allow room to add a few inches of soil, say around day 21, I would add a few inches of this new mixture as a top soil, and lightly feed CalMag as well as Fox Farms Tiger Bloom.... This simple formula (hopefully you have been building a beneficial microbe community since day 1) can give you excellent yields and keep a plant happy...

Here is image of my baby using what I described above at day 28 since she 1st pop'ed from the soil....

Not a big fan of purple pictures but you could be right, why do you suspect it could be your pH?

Because I don't consistently check ph levels. I do occasionally but after I add in nutrients it usually balances out pretty well. I'll try and get some better pictures this evening when lights shut off. Thanks

You think too dress soil and flush or continue with nutes?

@Roger A. Shrubber the coloration isn't right (looks like it was fed dye) and day 28 from seed, look at the flower organization. Also his recent Amazon LED post about yield. What do you think?

Looks like a Calcium deficiency to me too. The old leaves won't recover but watch for advancing problems to know if you were successful.

the coloring does follow the veins in the leaves, and seems to be absent in the pistils, where anthocyanin normally gathers. that's also a very odd color...very red dye number 5 food coloring red.....
the thing i have a real problem with is that plant being 4 weeks old from seed....i'm not an auto expert, but i've participated in half a dozen comparatives now, and not one single one of them was anywhere close to that mature in 28 days, and neither were anyone else's submissions ....he doesn't identify that as an auto, but if its not, there's NO way a photoperiod is that mature in 28 days. it would be an amazing mix of genetics and conditions for an auto to do that.....fucking phenomenal....

Yeah it looked all wrong to me too but I know zero about auto's. I've never intentionally grown one. Here's her journal over on autoflowers.net (she's littleMT)
http://www.autoflower.net/forums/threads/sweet-seeds-red-poison.68814/

Apparently she's deliberately light starving it.

the dates seem to check out. that is a strange looking little plant though...doesn't really look like the others that were posted in that thread, but maybe just because it isn't finished yet.

Every other day I water the two plants about a 1/2 gal each. Follow the go box feed schedule. Which is 10mg bio thrive flower, 5mg calmag, 5mg bio bud, 10mg bio marine. This is my second grow so still learning what I need to give the plants. Also open to options for future grows out side of the go box.
