Boron or potassium deficiency

Wow thank you again I see now what come as a new grower doing all their own research I've been implementing bits and pieces from different style growing w/o even knowing how drastic those effect can be thanks again I will be sure too give updates

With soil you need to keep your ph going in around 6.5, do not water to run off and never flush unless you are prepared to water with nutrients for the rest of the grow.
Never a need to check soil runoff that is for a specific type of grow style in coco or soilless only.

The soil mix that you stated above should have been good enough to PH water only for 6 to 8 weeks which would lead me to a little of a ph problem, a little toxicity problem, and a environment problem.

As mentioned above when your have a large temperature and humidity swing what happens is the plants transpire fast pulling water and nutrients through the plants to the air, with the low RH and high temperature that water evaporates faster then the nutrients can be used by the plant leaving burn, along with the ph problem and excessive nutrients I can see why the leaves look like that,

Up you frequency of water only when your temperature is going to climb.

you dig?

divlish and Mr Farley thank you very much that was my 3rd worry was nitrogen toxicity. the two larger ones after germination in coco pellets before tap root gets through netting I remove and put in 3 gallon pots w ph water until 3rd set of true leaves then I began half strength nutes transplant into the pots was Oct 14th the one in the smaller pot I simply was out of enough soil till the 6th it will have 1 more transplant I believe.
my watering is when top 2" is dry or they feel light the black pot is an air pot bottom feed but not fabric.
no more than 4days max between watering digital p.h. reader trying to get as close to 6.0 as possible because my runoff is at 7.2 to 7.4
first grow I used the drops to test p.h. by color and with my digital one my adjustment was not even close from how much ph down or up needed for plain water and after nutes were added

Heat is too high, humidity is too low. You haven't mentioned watering habits or PH levels and how long they have been in amended soil and whether or not you have started feeding them (supersoil is generally out of nutrients after a month or so).

Get your temp/humidity under control, water properly and make sure the water going in (with or without nutrients) is at the proper PH for soil (between 6.0 - 7.0).

For now I would suggest thoroughly flushing the plants with properly PH water and lower the temp to 80F and then leave them sit for at least 4 days.

Make sure they are getting plenty of light so adjust the height if the lights accordingly. 250Watts combined sounds like a lot but it really isn't so the height should always be around 20" - 24" from the tops of the plants

I'll leave the diy things like a 5 gallon bucket with a rag to wick ice water in front of a old hockey table fan blowing at the inlet for some of the others. I'm sure they have Ideas.

You're going to need a exhaust upgrade, plan and simple it not a cheap hobby and best i can tell you about that is thrift stores, Craigslist, eBay. The air needs to efficiently leave the tent and vent from the room. That (low Rh 27%- high temp 86f) is a big swings in my book that can cause crispy leaf like I see with the quickness. 14° temp and 25% humidity differences isn't a good thing indoors and can be a growers biggest challenge.

Temp and humidity can stay the same from day to night most grows can't achieve this and it is not really necessary (72f/55% Rh) high.

+ - 5f/2%rh high/low is a win for home growers. (74f/69f)
+ - 10°f/5% high/low is max without bumps in the road. (77f/67f)

Besides that, if you just transplanted how long has it been because I'd lean more at a toxicity then a deficiency at the look of thing without spotting the "small spikes" mentioned. All that mixing of soil and the hitting it with Gh products would be unnecessary at this age, more information is need for that conclusion on my end to conclude over-loving.

[Clutch707]

Thanks for your insight that's going to be my first thing to change

[Clutch707]

Also never had transplant issues before my first grow was even a worse setup and got 67 grams after curing and edibles that could put down a horse guess maybe beginners luck

[Clutch707]

Yeah that was a spike on both ends I am on a very low budget my exhaust is and old air hockey table fan and and an old vapo rub humidifier any hacks for low budget humidity and temp control it usually doesn't spike that high norm is about 75 Fahrenheit and inbetween 45 to 55 rh

[Mr.furley]

The wet soil on your leaves probably didn't help things but it happens.

By looking at your pictures, from what I see, 86f - 34% R/H with dry pots is were you should look first Especially since they probably have transplant shock.

[Clutch707]

Sorry about the first picture it says mad scientist because I sent it to him on Quora Digest can't seem to find original pictures

Hey Nation yeah I'm a super newbie and don't post much. Not sure how to word questions in proper lingo but here goes .
I'm growing bag seed genetics I guess???. They came from a personally known farmer that claimed it was mid-grade . I'm on my 3rd grow with 3 this time. They are all growing different but 3 different techniques. 1 is Manifold. 1 topped and lst 1 just lst.
the Manifold one which is the biggest with what I found my uneducated guess is boron or potassium deficiency..








Soil grow with coco starter pellets
2'x3'x5' vivoson tent
150 w dimmable growplaner
100w roleandro
fox farm ocean forest mixed with my own put together soil
Perlite, peatmoss, and black magic worm catings and potting soil
General hydro trio




When I put them in transfer pots got some moist soil on leaves that I rubbed off by hand I thought it was just damage I caused but it continued after the Manifold cut now new growth is clawing .




Thanks in advance all criticism good or bad gladly appreciated and happy growing
