I mess up bad some how . i have lots of pictures plz help a brother out.

something is definitely wrong. went on a trip had my wife take care of the watering not sure if she messed something up though because this happens on every grow but not this bad. randome leaves go yellow wish or dark brown color.
-they are 1 month in flowering.
-Promix Soil
-400 watt HPS with some CFL fillers light is about 20 inch above plant.
-I water every 4 days seems like its dry enough and needs water.
-add nutrients every second watering nutes I included pics bellow
- temp is at 30 but with lots of air circulation i have air coming in and exhaust out with home made cool tube. my temp is at 30 when i added cool tube.
- I have a humidifier in ther humididity is 40-50%
I test PH with the drops PH is at 6.5 but i think my wife might have watered it at 6 PH.
not sure if its magnesium or potassium or im starving them? even the green leaves seems fragile

beginning of the issue when they die

We are looking at some very burnt plants, flush and flush again, cut your nute feeding by 50% until you see a gradual improvement, in about 5 days, trash the CFL's they are doing little but stressing and confusing the plant, at 20 inches your 400w hps is kicking out 5700-ish lumen ...thats very little, compare to 63000 at 6 inches, improve venting by having better fan, or if in Oz or africa with high temps go 12x12 at night

to my blog: https://www.rollitup.org/blogs/blog32237-flush-baby-flush.html

that makes sense but i dont understand what you meant by "or if in Oz or africa with high temps go 12x12 at night"

they almost look cooked and 20" is too high for 400w. 30c is kinda warm (86f), are you sure the tops are not hotter? Looks like a few problems, roots not having the correct pH, ect.. they look pH burned a little by too much acid. the promix soil with plain water should be good for those plants, they are too small to need extra fert.. everyone gets sold on $$$ hydro ferts and gear and they forget to give a plant what it really needs. You are not having a mag problem, or any NPK factor. you might be having an issue with lack of calcium.

what is the ppm of your tap water? it looks almost like the roots are being cooked as well. take out the floros and drop the hps to about 12". Try to reduce temps to about 25c, my lucky number is 77.7f


I have "lights on" at night because it gets hot in Nor-Cal, that is what he means.

the only way i think i can drop the temp is to make the light vertical so the air travels faster up to the vent. is that ok? at the moment im using a 220 cfm untill i get a better fan.

Your babies are burnt up brother. I always recommend starting really easy on food. Read the plant. If you start easy you can always feed more next feeding. If your start heavy well you see the results. You can never go back.

hell yea, feed it too little before feeding too much.. it will just look a little yellow is all.. with a yellow but healthy plant, you can give it a standard 18-18-18 and in 2 days it will be vivid green.. If you burn them, they are burnt and NEVER can be repaired, only be re-grown. You can also turn the light on at night and open a window to vent the heat.

..remember that!

i tend to agree with heat issues as opposed to nutrient burn as those leaves don't show the signs of a nute burn imo..

im not sure but is there a bloom part a and b, maybe since that u been in flower for a month theres another nutez u should be useing i see u got dutch nutrient grow part a and b once u start flower i would think u would use a bloom nutez high

I do agree about the heat issue. But I assure you that the temp did not cause that unless they were dried out beyond wilt. If the lights were too close you would see it with burnt tops. I have had rooms that have ran in the 95-100 range during the summer time and I never had any issues. If you run co2 higher temps are better and most growers will tell you that.

Ph or nute burn thumbs up.

Time to start over. There is no shame in it. You learn and move on. I think if you try to save these that you are spinning you wheels.

i really think your correct. i think when i showed the pics to a hydroponic store i buy stuff from he said they are starving and at that point they werent so bad. so i feed them. and the thing that stands out to me is that the tops are fine its randome leaves getting like that and the big stem or branch seems it has spots or stains.

im not ganna start over these have buds on them and i think ill finish this and if im gonna make more mistakes id rather be this batch.

yup.. root problem too. think its from wet and hot soil-roots at pH in low 6? ya know, that could be ammonia toxicity as well. I can't find an ingredient list for DNF(and I never trust a nute who does not publish this), but I did find this:

Notice: In THIS link is says, "Non-Toxic" and "All Natural" as a product quality.
http://www.dutchnutrientformula.com/additives/additves.html

Look here and tell me if anything says, "Non-Toxic" or "All Natural"..
http://www.dutchnutrientformula.com/gro_bloom/gro_bloom.html


..makes me wonder what the fuk they are putting in that chit. lol

seriously.. what kind of a bloom formula is 3-0-3 or 1-0.5-3.. WTF? Dutch Nutes Form, more like Dutch Oven Liquid "stuff". No offense, just poking some fun at DNF.

if im gonna make more mistakes id rather be this batch.

that is some seriously good advice to yourself, we all have.

really? this dutch stuff is shit? errrr i guess you get what you pay for.

Realistically the problem was caused by the hydro store. They clearly should have advised you to use a very forgiving fertilizer, being that you are a newer grower. They could have advised you to use a medium with some food in it ocean forest/roots just to name a few. HP can be used by a new grower but he should have a consultant being that it is a soilless mix/peat moss edit let me correct myself has many beneficial bacteria but has zero added fertilizer.

i will do a flush with 7 ph water. and ill look for new nutrients. these numbers are confusing 3-0-3 or 1-0.5-3 etc. in a simple way what should i look for when buying nutes?
all natural no toxic what ales? thanks everyone for taking the time i will hopefully be able to pay forward.
