Problems

Hi

Can anyone tell me or give me some idea of what’s going on here.
Feed guano and cali mg
One almost looks like a cali mg problem however its have had loads of it
Am I not feeding enough or have I feed to much and locked out nutes.
Could I be Feeding to much cali mg
I did back of on the guano when the yellowing began.
Could it be Bad watering practice ; letting them dry to much in between waterings and then not watering enough.
Organic grow so it’s not lightly to be ph related. Obviously any ideas at all that help me are greatly appreciated

Look to me like it want's more nitrogen, (yellowing leaves from the bottom up). It's not a calmag issue unless there's so much Ca it's screwing up uptake of other nutes. I'd back off on the Ca and add some N.

Ok thanks
I may have switched to a lower n guano to early and it ended up causing this,
I see you guys prefer lights off photos.
I’ll add that just in case it helps.

That well could be the case
I was a hid grower and never touched cali mg
The first one under the led had a cali mg problem and I was told they need loads of it and you can’t overdose. so they have been getting a lot , thanks seems to make sense thinking it over

Tbh I’m impressed first reply spot on, all this because someone gave me bad advice when I switched to led.
I though over the time line; I was using a guano with a high n when they started going yellow however was using x loads of cali mg.

Whoever told you that you can't overdose Ca. was incorrect, you aboslutely can, it will screw up the uptake of P, and K, and some micronutrients too! There are differing opinions on whether LED lights cause the need more Calmag.

Yeah they did me good. I should have figured as I have been growing for a long time.
However the led i not had long 2 harvests and am like what the heck as it kept happening on week five. It was on a different forum thou witch I ditched.

I had a hell of a time switching to led until I sucked it up and bought a par meter. Life changing

Haha maybe one day but I gotta replace my tent when this lot comes down as it’s getting to old. More money if I don’t crack it next one I will probably go nuts
