People do the 18/6 because it'll still produce bud, and it might maximize harvests since they're getting more...I've heard of 24 hr autos..

Hey guys,
I really need your help on this one. I cannot figure out what kind of deficiency or stress this is. We were doing really bad on the Cal-Mag but got that sorted out thanks to Dr Frankenstein. I'm thinking possibly heat stress or over fertilization? Or maybe it takes a little while for the magnesium deficiency to clear up (it's only been 6 days on proper levels and spraying leaves with Epsom salt for 3) Here are a couple pix thanks in advance

Can't reverse that type of damage, you can clearly see in pic 2 and 3 that its crisp yellow and can probably crumble to the touch.
Can be a million things, if you're flushing I wouldn't, as thats what happens.
Over fertings, then feeding with nothing but water also causes this because the plant leeches whatever it can while you're feeding water only and it tends to not get all it needs.

Its a double negative

No I'm not flushing I was just wondering about the calmag for future reference. So what do you suggest flower as long as I can or harvest early? Not all of the leaves look bad just maybe 20-30% of them are like the pictures and the flowers still look healthy. Initially I was giving it too little calmag I'm pretty sure that's what got me into this situation.

And I was also giving a high recommended dose of maxi bloom as well. I'm thinking it's a bad lockout

What's the temps looking like? Looks like there's also heat stress..i had a little of the same problem but no where near as bad..The leaves in the back round look like the points are curled up...just a guess I'm by no means an expert just trying to give u some ideas..

Thanks guys. My pH has been at 5.8 for as long as I remember so it's probably too much nutes. And did spike to 90 once for like 2 hours but I've been on it lately. I'm more concerned with the fucked up colors

That's a good picture of what happens when you get lazy, been there done that. Move the lights up a bit, good flush new food at 50% and get the humidity up to 60%, spray your girls with a real good topical product like H&G Majic Green, things will pick up.

Use 20% tap water with your RO when you flush not cal-mag.

I'm curious how long everyone vegged their plants.........I have 30 going right now and they seem small for being in their 3rd week of growing. Mine are very healthy, it's been an easy grow, but they are growing slow in comparison to other strains I've done???

Yea I think they are gonna pull thru..I'm in what I would call the final week or so now so I'm just gonna flush. No nutes or foliar sprays. But that's a really good idea for using a diluted form of tap water instead of Calmag. I'm sure it was from giving my plants the max recommended dose over the span of their cycle..oh well live and learn at first I thought the discoloration was the onset of mold or something..I'll take a deficiency over bugs or molds anyday, just next time more Calmag and less maxi series. I'm just lucky this strain is so strong cuz I have made countless mistakes on this (my first) run.

Also, I vegged my girls for almost 2 months that's y there decent, if u have the room I'd try the SOG technique if u wanted to yield fair accounts quicker..that's what I wanna try when I get my house
