Yellowing On Fan Leaves And Brown Spots

looks like a N deficiency, plus some light bleach/light burn on the upper set of leaves in that one pic. For one, you should def should invest into a ppm/ec meter and a ph meter. also get some calibration solution as you will need it sooner than later after u have those two tools. But as far as the leaves the yellow ones will not recover. They will continue to yellow out then eventually die. The yellowing/dying of the lower leafs are a normal thing in flower to expect. The main thing you should be worried about is when your new growth begins to yellow out and die, thats when you have a real problem. Also keep check of your light levels, 18" is a good height but make sure that you have a fan circulating the air under the bulb and also hitting the tops of your girls at the same time, if that makes sense. Also how often do you feed them, water water feed, water feed water, etc? It also looks as if you have the "claw" where nutrients may be locked out due to the ph of the water being off, always add nutes first then ph water and adjust if needed.
 
Ok so i just watered at lights on and kept watering till run off appeared...thats the 2nd day now that ive just used water but this is the first ive watered right thru till run-off appeared,does this count as a flush if used just PH'd water...i used my little basic test tube PH tester kit and it came out at 6.5 which i think isnt too bad

The water i use is tap water....i leave in open air minimum of 24hrs but always try and stretch it to 48hrs

Its the feeding thats let me down,i took advice from a friend on the feeding patterns and was informed to give it the same amount each morning.....which im now believing to be way wide of the mark

I should be feeding them till the soil is damp thru-out and then waiting on the plant telling me when its needing fed/watered again by the dryness of the soil

Im using a 14" diameter blade 3 speed oscilating fan which is positioned along the top off the light and reflector,fan head being at the open end of the reflector. Its tilted to a 45 degree angle so its blowing across the path of the lighting and across the heads of the 3 plants...i turn the speed down to 2 at night to limit air cool when lights are off so it dont drop too low and damage them

I was thinking of putting to smaller 7" fans too the bottom of the grow area and angle them at 45 degrees from each corner to create more air at the bottom as the top fan is above the main canopies of the 3 plants....would this help in any way?
 
Ok so i noticed you mentioned a PPM/EC meter....ive just read up on it as its the 1st ive really heard of it....it tells me what nutrients are in my soil.....handy bit of kit then i presume and a must have for growing.....so this pen will tell me what the nute levels are in the soil right?

apologies for the never ending questions but im keen to learn and if yous guys could point me in the direction of products i need then ill gladly read the info on them myself so im not leaching too much

What do i need to buy to sort each deficiency as id be aswell purchasing them all today when i go for the meter :)

Thanks again and +Rep for John12

You can find them online for cheap, found some on amazon for twenty for the ppm meter, its blue and made by hanna montana I believe, hanna something lol then there is a yellow milwaukee ph pen that I didn't like at first but once I got some 7.0 solution its been smooth sailing but find it rather hard to get a correct ph reading on water without any nutrients in it but with its just fine. But the ppm is probably the most recommended tool by me cause you can always just use the drops for the ph reading. The ppm meter with tell you how much nutrients you have in your water solution to help eliminate over feeding and to se how much food your pants are eating, super handy when doing hydro, a must/need to have type of tool. And did you say you water everyday? that's over watering for sure. You wanna keep note of how heavy your pots are after you water them and only water when they feel light and not heavy, if the top of your soil is damp in some spots then you won't need a good water for at least a few days. And don't feed then feed again next watering. I recommend a feed water feed water, where the water days contains only additives like sweet and big bud. Feed consists of the additives and the base nute which is flora nova bloom. Any other questions feel free to ask.
Also as far as deficiency you will need to look online at a "leaf issues" search results cause no meter will tell you what is wrong with your babies, at least not yet. Just search for nutrient deficiency and you should come across a few sites worth bookmarking, just don't have them on hand
 
Just watered them again thru till i seen run off,thats the 3rd day now ive done thta so im going to let the soil dry out now and see how the plants look come tomorrow or sunday depending on the soil....and if they are looking healthier and green ill start up on 1/4 nutes for 1 week then go upto 1/2 for a week....then ill pop it up to 3/4 and run at that too see if its better for them

Going to try the weight method like you suggested when i get them looking healthier again

Ordering the PH and PPM/EC meters today online and ill get cracking from that

Thanks for the help :)

Peace

this sounds like overkill, but believe what i tell you - it's GREAT for your soil
now that you have a feel for how much water it takes to water to runoff...
take plain, no-nute, Ph-ed water and measure out approximately 2/3 of that amount
water steadily and evenly all the way around your plant
move on to the next plant
when you've watered all plants that get watered today, wait 5-10 minutes(smoke a bowl)
now mix some nuted Ph-ed water
now go back to the beginning and give each of those plants 2/3 of the amount AGAIN
if itt is not a feed day, then do the same with plain water both times
i know that 2/3 + 2/3 is 4/3
"but that's a LOT of runnoff"
nonono - that's a lot of salt washing out of your soil that won't have your Ph phukked in a week or 2
leaving it in for several minutes allows the old nutes and waste buildup to soften/break up a little to more easily wash out when you add your fresh nutes
it's the buildup of that bullshit that gets your plants all fucked up
if you use this method to water, you should never encounter Ph issues
if you can, you should always try to have at least one plain water between feedings - 2 is better
your plant will die much more slowly from under than over nutes and dieing slowly is really kinda what we hope for them lol

the plants look really nice man
hionestly
the bad shit at the top, i gotta agree looks a lot like heat
the rest of the plant looks like a minorish nitrogen issue
great job man - i brought to harves way shittier looking plants than that my first round lol
truly they're very pretty girls - just a lil acne man

be careful keeping them water logged for days and days man or you'll end up with a whole new cuppa worms

your plants REALLY DO need air in their roots
your plants CAN drown - no wait - your plants WILL drown
your roots will stop taking in anything
your growth will completely cease
your plant will go into shock
your plant will wilt
your plant will die

i am NOT saying you killed your plant
i'm saying DON'T

don't give your plants anymore water until it's dry
not arid - dry
not cracked soil
not soil pulling in from tub
to check my soil, the first thing i do is put my hand nice and flat on the side of my bucket in the center... if the bucket feels cooler to me than the ambient temperature of the room, my plant is fine - if the bucket feels room temp to me, i give it a lift - if it feels light to me, i water.
another crazy sounding but great way to check is this
water your first plant
slide it next to a plant that needs water
slap(not HARD but firm) the side of your bucket at about center
now slap the other bucket about center
mmhmm - i'm awesome

relax - the reason(only) to grow in soil is because it's peaceful and relaxing - earthy, one might say.
you're doing a great job
think of it like your wife or child - even if something IS wrong and even if you don't have a CLUE what to do, you can't let THEM see that or THEY'LL panic

relax and take it in - stay calm, stay logical, and take your time and you will (practically) never kill a plant in soil
 
Thanks very much sir....im trying my best too learn as i go along and hopefully ill get some bud at the end too puff and appreciate the effort ive made in trying to make some of mother natures finest product....MJ
