Here is what I got going on, can anyone give me a general idea as to what could cause these issues on my upper fan leaves.

It took a turn for the worse after the last watering. It got half dose of mega crop. Here is the full plant.

I was told I was getting light burn from the LED I had in there for a few days, so I shut it off. But it kept getting worse.

Here is my other plant getting mega crop that was further away from the LED.

So is all this just aftermath from that light or is something else going on too?

I'd spray her with a calcium foliar.
Such a thing can be purchased as a tomato end rot preventative.

Here is how it's progressed. It doesn't look too good. I just gave it straight water yesterday. I am a little worried spraying anything this far into flower tho.

I had a plant do that I blamed it on the fans blowing to hard on them. I cut off fan leaves that were discoloured didn’t happen again

Hmm... i never thought of that... it IS the plant right by that big industrial fan.
Yeah if all the syptoms only show on the leaves that are closest to the fan or in the pathway of blowing wind then it is probably wind burn. I had something like this when i left for 10 days. Now i turn them and move the fan periodically.
But also, if i were you, i would stop with the nitrogen from now on.

Now that I think about it, it's probably not wind burn because some of the leave are in the middle of the canopy. I do turn the plant a quarter turn each day.
I do think one of the plants is getting too much nitrogen. I used miracle gro perlite in one pot, then realized it had slow release nitrogen, so I got a different brand for the other 2. Not sure which one it really is tho lol.
Is the nitrogen in cal-mag too much? Also, I really have no clue what is in mega crop lol. It's supposed to be like an all in one, for veg and flower.

How far along they are? How many more days according to the breeder.
I would definitely back off with nutrients at this point. They look full of nutes already and you want a slow nice fade at the end to get a cleaner smoke. I know its tempting to feed but it is counter productive to feed to much.
Good call with changing the perlite.
I definitely suggets different ferts for different life stages. You cannot give the same shit through the veg and flower. They need different things at different moments. There should be a npk value on the bottle you can look at that and see how much nitrogen you are giving.
Cal-mag has nitrogen in it too. I have one from a company called aptus and it has a npk value around 9.0.0 and ca and mag. Now, i have only used it once this grow and 2-3 times last grow. I don’t try to correct things that are not there. If you are not in coco and/or not using ro water, why waste your ferts and stress the plant.
I hope it was helpful

I am 6 weeks in. They recommend 75 to 85 days. So basically 11 weeks or more. I have 3 plants. 2 getting mega crop. And 1 on fox farm tiger bloom. It's fading nice and way more mature in it's bud growth. Although mega crop buds look bigger. I got a journal going on if u ever get a chance to check it out.

Oh, I forgot to add, my cal-mag is 1-0-0 and I use it because I am using distilled water.

Are you having the same issues with the tiger bloom? When i google megacrop i am seeing 9-5.5-14. Less nitrogen would be ideal. Too much nitrogen delays ripening if i remember correctly which you are experiencing first hand (or different phenos, who knows :)). They need high P when setting the flower sites and K to ripen that flowers basically. N is just there to keep the plant green at this point. It does not contribute as much to flowering.
What would be ideal, if you like to bottle feed, using a light mix soil, starting with megacrop, using tiger bloom at blooming and finish with something with lower N and P and higher K.

I was just wondering if I should switch them to tiger bloom? Here is my fox farm plant. They do look like different phenos to me but it is way more ripe

I think you should just cut fertilizers all together and water only with some molasses if you have it. Yeah it looks more ripe, it could be phenos or the low nitrogen, who knows.. but even the one getting tiger bloom looks deep green, i mean deep green. They look well fed and they will be done in 5 weeks so maybe just leave them be and only feed if you see any deficiencies from now on, or maybe go 1/4 of what you have been giving to maintain.

I will just cut nutes unless they desperately need it. Should I still use cal-mag with my distilled water?

Not sure i am not using distilled water so i don’t usually use cal mag. But at least lower the dosage. I don’t think those plants need much for the rest of the ride.
