Help Me Stitch!!!!!

[Heavy Chevy]

Well if it helps these babies are about 2 weeks from seed
Daytime temps are about 77F Night time is 69F
RH is about 50%
400w HPS
Fox Farm Ocean Forest with 25% perlite
First week i was watering with tap water and i believe my pH is around 7.5
Then i changed to distilled bottle water

It seems to be either pH related or maybe calcium? this has plagued me through all of my grows and its very frusterating. it starts on the oldest leafs and works its way toward the stem then on up the plant.

Start by lowering your ph to around 6. http://www.icmag.com/ic/showthread.php?t=32760

 

[420guy]

7.5 is kinda high even in soil...try lowering that first...maybe the 400hps is just a little too strong for the girls at that young of an age...certain strains don't like such intense light so early..good luck...stay safe

 

[MynameStitch]

ok water ph is 7.5? if so thats NOT a problem, its the soil ph you wanna worry about

not to mention you are overwatering your babies, how often are you watering and how close are that hps?

and what kind of bottled water are you using

if its got additives in it STAY AWAY from it and use something different

distilled water is kinda like RO water, and requires a little more nutrients than what you would use with regulaer water because of the ppms of the distilled water

what you need to do now is check the ph of your soil mixture, get some ph test strips or digital ph pen and calbrate it, water them when they need it and get the run off from the plant and test it

its so early right now i cant tell 100% but i think i might have an idea what it may be

 

[Heavy Chevy]

I usually water about every 2-3 days with about 3/4 of a cup going into each 18 oz cup. The excess water drains out the bottom through holes that i poked in them. The hps was about 12 inches away and i adjusted now so its sitting about 18 inches away from the tops. I was thinking i might cause some light bleaching? As for the water here is what the label says:

 

[bp420]

what i do when i grow in soil is i weigh my pots. i weigh them after i have watered and let them drain for 15mins, then i weigh them when they are completly dry (right as the plant start drop slightly)
so, for example if the cup or pot weighs 500g when wet, 100g when totally dry, you can work out a rough idea of when to water it.
its a very vague way of doing it, but it can give you *some* idea of how long between waterings.

the reason i do it this way is because on my last soil grow i had a few plants that drank water like there was no tomorrow, and a few that drank fuck all water.
so what was happening was if i watered say, once a week - it was good for some of the plants, not so good for others. by weighing them i could see that some plants could take a good solid watering every 5 days, where as other plants wouldn't need to be watered for upto 3-4 weeks.

i think what alot of people need to realise with soil growing, is more water doesn't not equal faster growth. watering every 2or3 days is a little excesive to me.
by acctually letting your pots dry out occationally it will promote better growth, because it forces the roots to go in search of water - thus making them grow.
bigger roots - bigger delivery method for nutes - bigger plant. the key is not to dry out so far that it stresses the plant tho.

 

[420KushMaster]

bp that sounds about right if you have your soil always wet the roots dont need to grow and find water.then root rot molds ect are lurking. i water when my tops soil is dry every 4 days or so and they really do alot better than when i was watering everyday way back when.

he theres stitch long time no see

 

[MynameStitch]

your plants are not showing signs of watering issues
when you test ph what is the run off, or are you just testing the ph water?

if it was bleeching the otehr leaves would show problems and your leasves would be curly or crispy brown

have you checked your plants for pests? on the left side of the leaves it looks like it was munched on

but do you have pics from your other grow that you have problems with? did this the way your plants look progress into something that you had before and have pics of it?

 

[Heavy Chevy]

No i don't have any pics of my other grow, all my pictures were on Overgrow... Yes i check with my handy radioshack microscope on the underside of the leaves and there are no pests to be found. And i will get back to you with the pH runoff, i am waiting until they need watering again because i don't want to flood em with too much water.

 

[quiddler]

I think it looks like heat stress as well as a pH issue. Stitch just helped me with my first grow crisis as well. Moving to bigger pots now will also help, mine literally took off overnight when I moved them from solo cups to 3gal buckets full of FoxFarm Ocean Forest.

Listen to Stitch...Stitch is good...Stitch is wise...

Peace

 

[MynameStitch]

i was thinking of heat stress too, but its so odd because its spotty and not the other leaves are affected

do you foliar spray or mist plants chevy?

how close are your lights and what is the ph of the run off water from your plants?

lol quiddler, i try to be

Check your roots before the next time you water when the soil is dry. I have started plants in those 16 oz. cups a lot and I can't ever get farther than 2 weeks before they start to become root bound. Like someone else said, I would strongly suggest that you transplant.

[Blackmelo]

at that stage i keep my 400 w hps 30 inches away.

12 seems awfully close and so does 18... you want it that close in flowering, not seedling stage

 

[Heavy Chevy]

Yes i have been misting daily but have not misted yesterday or today. I check the run off and according to my little test strips my pH runoff is 5.0 or lower... I will post more pictures today after i repot and water as the problem does not seem to be going away...

 

[MynameStitch]

ok then thats where the spots have come from then

the light is to close causing the droplets to bleech

alot of people say its not true and say its true but it happend with me once when i droped some water on my plants and it stayed ther to only come back to spots like that on my 2nd grow

like blackmelo has stated you do need to move the light up, i was consdiering to much heat but the rest of the plant wasnt affected which came to me as very confusing and which is why i asked if you misted them because that would only be the other logical problem that would cause them to be like that other than pest issues with spotting like that

stop misting right now, they dont need it and move the light up, and make sure your run off of ph is good, from right now i dont see a problem with ph as if there is a problem its not showing it yet.

But im almost certin now its from the light being to close and misting your plants

 

[Heavy Chevy]

Does Anyone know what this could be coming from?

White Rhino

Northern Lights x Big Bud

After Transplant

Moved 400w so its about 24 inches away from canopy

These needed to be transplanted for sure

 

[MynameStitch]

how often are you watering your plants?

and stop misting your plants!
and stop using distilled water, water your plants with tap water as long as itsw not softwater

your tap water is fine
distilled is almost like RO water but its sat much longer, its got almost no nutrient value, all calcium magniseum are gone.... plants still need the nutrients from water to be supplimented, but how can they if three isnt any in the water?

 

[Heavy Chevy]

The misting will stop right away aswell as the distilled water use... I will also go back to using tap water. As for tap water should i let it sit for 24-48 hours or is straight from the tap ok to use?

 

[MynameStitch]

yuppers, also how much are you watering and how often?

your plants really seem to be overwatered and the soil looks soggy
