Hey everyone...I needed some help with getting my plants to optimal health before flipping to flower. I have 2 problems (probably way more but two that I know of) and need thw eye of an expert or experienced grower to help me out.
Problem 1 is the folding of the leaves on the top of a few of my plants. In one day they have suddenly began to fold upward. I've included a picture for diagnosis...
Problem 2 is the discoloring on the leaves of one of my plants...Once again, pictures are below. Can anyone tell me why or what is going on?
GROW INFORMATION...
Im growing 6 plants in a 4x4 tent under two 240w 3500k Meijiu LED lights and am watering and feeding using General Hydroponics Flora series (1/4 strength) and cal-mag (1/4 strength) at a PH of between 5.5 & 6.5 .... 5 of the plants are gelato 33 × wedding cake from seed found in an ounce I bought and the 6th is slurricane from purple city genetics.
If any other info is needed, please let me know! Thank you in advance...

-Carson

Looks to me like you have not been giving them any calcium or Magnesium ( CAl MAG). I would suggest as little as 5 mills per gall or up to 10 mills per gallon based on your lights PPFD range. With PPFD ranges around 1800 you will need the higher does of Cal Mag. But your plants are def. so I would use 10 mils for the next week or 10 days and then back it down to less.

Wow, okay thx for the advice. Actually, yes, I have giving cal-mag but I guess not enough... Do you know what the problem is specifically? Is it calcium or magnesium deficiency? What about the leaves bending? Thx for the help!

The spots look like cal/mag deficiency. The curling looks like over watering. To me at least.

The problem with cal mag deficiencies is it will cause other nutrients to have issues with uptake. So you can have several problems arise from the one root issues. Generally fixing that should help, if it is really the problem.

Thank you. I appreciate your help, its my first grow and up until last week things were perfect...Trying to get back on track

The leaves do that when they are over watered? Wow, I had no idea! They dry out daily and I try to only water when that happens but could be too much...thx again

Exactly what I was thinking, it could be lack of Mag or out of the ph range.

Don't just take mine or any one person's advice, even though it looks like that to me it could be a number of issues.

One thing I have seen a lot of lately is a new person posts asking for help, and ends up maybe listening to the wrong person, or gets a little too focused on what one person has said and doesn't consider other advice.


The best advice I can give is try to read what everybody has to say, weigh it out in your own head and act accordingly. There are a few people here I would listen to without question but just remember not everybody on here is a pro.

Again, good luck!

Well you actually have both a calcium def. with the brown spots on the leave and the leaves tacoing and the slight irregular shape to the new leaves is a classic start of Magnesium Def.

Okay, thx...I totally understand. I figured a small dose of call mag wont hurt them, and after looking online, the diagnosis you guys are speaking of seems correct. I just dont get why this happened...I was only recently able to PH my water after nutrients, so perhaps before the calmag was out of range for absorption? Just a thought...thx again everyone!

Im going in with 5ml for 2gal water... Thanks for the help! View attachment 1105354
2 1/2 mills per gallon is not going to solve the problem. Your plants are already def., meaning they will need more to get back to happy.
The problem has to do with LED lights. It use to be with 1000 Watt DE HPS running 5 mils per gallon of water was the norm, but with increases PPFD the plants will be consuming much more Calcium and Magnesium. I run 10 mils per gallon and I have to add even more to the res at times during the grow because the plants are consuming more. Lucky for me the Cal Mag I use has a dark brown tint to it so I can get an idea of how much the plants are consuming based on the color of the nutrients in the res.

Jesus, im not giving them ANYWHERE CLOSE TO ENOUGH! THANKS!
I would say hit them with about 10 mills per gallon on the next watering and then maybe back it down to 7 or 8. The plants will probably lock out for a few days to a week based on what I see, but they will bounce back. You will know when they are getting better by when they start drink more water again. What is your media?

Damn, I really do appreciate it. IF this issue is fixed in a week or so, would you still wait a few weeks for them to bounce back to full health before flipping to 12/12??

I would recommend holding off on flower until they have bounced back and are totally healthy. One thing I would suggest to help is to turn the lights down to about 50 percent until they bounce back. That will help minimize the grow rate and keep the plants form out growing your tent. You can also turn the heat down about 7 degrees to slow growth and lower the humid about 4 or 5 points. You are in soil basically and thing will get a little worse before they get better. You will have to be patient, this problem actually started 3 to 5 weeks ago it just took that time for the problem to manifest itself and be visible.
