Calmag deficiency or something else?

[BazookaJay]

Growing Fugue State, at around day 50. Growing in Fox Farm Happy Frog and Amended soil (bottom 1/3rd)

Haven't added any nutes but thinking I might need to. I'm not trusting my cheap PH meter, it shows between 7 and 7.6 no matter where I stick it. Organic soil is supposed to help keep the PH in check.

All help and suggestions are appreciated. Calmag plus has been ordered and on the way.

Give her a good soaking with cal/mag when you get it and use it every time you feed her.You should start feeding bloom nutes now and hopefully that will help.

Thank you. Any thoughts on dimming the veg spectrum at this point?
I might goto my local nursery and pick up some bloom nutes today.

Fed her calmag and Fox Farm Big Bloom. It says to dose twice a week with Fox Farm but maybe dose with each watering for now since she was deficient?

Update - been lightly dosing with calmag and big bloom. So, I'm beginning to notice a pattern. The leaves shielded by other leaves are not damaged. One leaf had half of it covered. The covered part was completely green, the uncovered part was rusty.

Can it be LED light burn?... or did the initial nutrient deficiency impact the plants ability to absorb the light?

Giving it 60% veg, 100% Bloom via 300 watt generic light. Tip of top bud is 16" away from light.

you need Tiger Bloom, that's the actual base bloom nute, BB isn't what it says it is = ... great product, stupid name! Look at the NPK#'s, all in the decimal range, beyond weak,... treat it like a supplement, use at full strength a couple times a week,...
Can you get me a pic of that leaf? indeed, there's a definite correlation to elevated Ca demand with LED's, though I;ve not found out exactly what it is,... anecdotal evidence is mountain high though! How far away are the lights, what brand and type (COB?)

Maxisun 300 watt LED. I did a soil test yesterday. Plenty of nitrogen, PH about 6.3-6.5, Deficient on P and K, especially the K. Don't know about Cal/Mag but will keep adding it along with extra BB.

Here's some updated pics, for some reason they are a bit blurry. Thanks for the responses. On day 57.

literally the opposite of what you need on that test! ... get on the Bloom ASAP mate, to finish her well....

I don't have any Tiger Bloom, can I just triple the dose of Big Bloom since it's considered mild?

Hey bro I have the exact thing! It is 100% led light burn. And a calmag issue. Those wierd half faded yellow lines near the top are the light burn. The mid fan leaves getting yellow spots then turning from tip to base is ur calmag
