Deficient or burnt?

Aloha RIU, I'm overall very pleased with these two TSS's but am wondering what is this small problem I have here, should I give a pure flushing watering, or should I feed the girls again... last feeding was with 1050ppm RO water with some FF grow, big bloom, tiger bloom, and some molasses,... over the next 4 days all they got was 20oz of plain water... then a half gallon of water with only about 1/4 a tsp of Open Sesame last night... it seems to have gotten slightly worse on one leaf over night... i don't want this to get any worse! Help! Thank you all!

I hate seeing 0 replies for someone who needs help. Ppm of final nute solution is much higher than my r/o. Mine is 300 to 600 after I mix. Are you using full strength? If u are then cut back %20 to %40. That curl looks like either nute burn of ph is off. What do u ph your nutes to? How old is your soil, if it's new and you are putting nutes in it will undoubtedly burn (depending on mix). If it's new soil and u added nutes then flush with 3 times the amount of medium (clean plain water) and give it a half strength nute dose. U should ph between 6.5 and 6.8 for soil (but can go as high as 7). Good luck bro, I'll try to remember and check back

I am not using full strength, I used a half strength nute mixture based on the FF feeding schedule, plus I added less than a 1/2 tsp of all natural Molasses. My PH has been between 6.3 and 6.7 for every watering, I'm afraid that I got a little zealous because this past watering instead of doing a "every other watering feed" like the instructions say I added a little open sesame to the mixture because I didn't have it yet and should've added it to the last feed. So you think this is a burn and not a deficiency? In that case I will do a pure RO watering next instead of feed again. Please let me know what you think people, your experience can really help me!
Thank you Backnine, I hope to hear back soon! God bless!

plants look like they can use cal mag from what i see in your 2 plant pic. if your new leafs are small and cupped and lower leafs are turning yellow and falling off then you need it. vertical growth will stop and leafs will contort and look nasty (nodes will be so close together like right on top of another because vertical growth stopped). if ur plants are like this then grab some cal mag and add it with your nutes....5 ml per gal. i had this prob because r/o strips the water of calcium and magnesium. but by what u say the plants should be fine, so sounds like cal mag def to me (not sure if FF has enough calcium and mag for r/o water though).

Growth looks great except for those few spots, so you think this is a deficiency and not a burn? My plants are trying to tell me they want more carbs? I'll look into some Cal Mag or something equivalent. Thank goodness I don't have any leafs falling off, or any serious yellowing, if this is as bad as it gets then I can live with it, but if I can better care for these gals then I'm willing to do what they want.

Ya take me some closer pics of your newest growth and I'll tell u what it is. But ur plants look good. I've never worried about carbs... It could be early deficiency signs (maybe) but more likely your PH is off. Make sure u PH your soil from 6.5 to 7. A safe way of solving problems is to just flush with 3 times the amount of soil and feed with nutes. I flush once per month (or something around there) just to keep my plants healthy without buildup (soil that is). So whether or not that's what it is, it's a good idea. But by what u said the plants shouldn't have gotten burnt. Good luck

is that tinfoil on your walls? if so you don't want to have the shiny side out, it can create hotspots that can burn your plants if your using hps or mh

I will get some more pics to see what you think, there's one leaf in particular that I'm sure will tell us something, it's only one finger on one leaf but it definitely doesn't look like it should, I'm going to give it the rest of today to tell it's story and I'll put up a pic later tonight. I fed last night and gave a little grow to the plants, as well as everything else I have been, it was about a 600ppm mix consisting of 1 tsp grow, 1 tsp tiger, and 1/2 tbsp bloom, and just a touch of open sesame, about 1/8 a tsp. I only watered with about 1/3 a gallon, so it was a light feeding...

Aluminum Foil:

Aluminum foil is no more than 55% reflective - if used, make sure that the dull side is the one that is used to reflect the light. When it becomes creased its reflectivity is even lower (around 35%.) It is also very dangerous to use because it creates hotspots easily, is electrically conductive, and is a fire hazard when it is in close contact with HID lighting. Attaching this to walls is a pain and usually using aluminum tape or glue is the best way. This should only be used as a last resort, and even then its usefulness is questionable.

Here's the worst of it right here, all of it on the one plant topped just after the 3rd node... could it be stress or bad gene's maybe? I would hate to think it stress because i've tried to make these two very comfortable.

nah not genes. nah not stress (stress doesnt burn like that, the plants would slump over or wilt or just not look happy if stress was an issue). looks like some kind of deficiency or kinda looks like bug damage or maybe u splashed some nutes on them under hot lights. have you seen any bugs in there? mature bugs suck on the leafs and cause spots just like that. but they are usually just spots, not large areas. the plants look good other than that burn, if thats all it is then i wouldnt worry at all, your fine. PH could also be wrong. give a pic of the tops of the plants

Here's a current top pic, I didn't think of that, I might've splashed some nutes on that leave by mistake, though it's not getting that hot in this tent, temps have peaked in the low 80's in the dead 95 degree heat of the summer. I hope that's all it is. Everything is looking good other than that though, new growth is very pretty and lush green.... (hard to tell under a hps)

Just to give an update, I never figured out if that was nute burn from uptake or splashing, there are a very few small places on the rest of the plants older growth that have a insignificant amount of yellowing, if this is the worst I see through the life of this plant then fire up your bongs, this is going to be some great smoke!

Ok, so it's not just nute water getting splashed, definitely something going on. This site has helped me so much, I'm sure you guys can pull through for me this time... all growth is older, and has a fan blowing on it at point blank range, but all this discoloration, i don't understand? If this is getting worse I'd hate to think of where I might be in 10-12 weeks! all other growth is lush and dark green and healthy week4day2 of flower. a few bud shots in there too for reference

Also,

here's an entire account of what i've fed/water how much and when... if you really wanna help.

Bump. Someone has a suggestion I'm sure. What am I either not giving this girl, or what is she getting to much of, She's been babied and has been lightly fed, so I wouldn't think it's burn, unless I just gave to much of one thing, I don't know! Help please!
To feed her stronger should I just increase the individual amounts I'm using or should I increase any one thing? Fox Farm nutes, full line, 3 basic nutes and the 3 supplements. also a little molasses in there, but very light so far.... I've actually only included it in maybe two waterings.... it's all in my journal. Help please! I don't want to get desperate!

The plants are in Oceans Forrest from FF as well.... I refuse to believe everyone that's looked at this doesn't have a clue? If you could even point me to another thread that might have helpful info in it then I'll gladly go do some reading, I'm not lazy, I've done some digging and I'm to the point that I need more sources and help...

Bump.... about to start begging...

Here is a link to my journal, can anyone find where I went wrong? In my last post I note that perhaps me putting open sesame in the mix might have contributed, but that nute is high in P and this doesn't appear to be a P deficiency according to what this thread here says:

https://www.rollitup.org/marijuana-plant-problems/157345-have-plant-problem-check-here.html

I have always PH'ed everything to the correct range and my temps are not out of whack.
