I have 3kk chem fire under a 600 watt bare hood 5 gallon buckets those are the ones getting brown rusty spots on the leaves on the other side of my tent I have another 600 watt with 2 bubble bombs and 2 unknown strains bag seeds and they are doing great no brown rust spots! I'm stump here! need help fast. Lol any suggestions can't find any bugs looked real good with jewelry loupe 30x. On week 3-4 of flower 12/12
Roco,

Read that post above by sister Mary and shot hole on page 735. Lay off the Mg, that is the problem, too much most likely and low Ca. Add gypsum and fine lime and milk.

Soil analysis would be easier, but I would imagine that you have too much K against P, due to low Ca and high Mg, probably overwatering and most definitely Mn and Zn problems, might be B too. Any conductivity numbers from the runout?

Calcium problem, plants are growing too fast and can't pick up calcium fast enough. How is your boron level in the soil? Do you have a soil analysis? Are you using nitrates? There is a visual zinc deficiency, I see lots of grass, that means high K and little Ca, some serious taco going on, twisting leaves on new growth, classic calcium deficiency, usually induced for pushing K or being in washed out soils, that have nothing to begin with.
Thanks for the help.
Iv been feeding them with babie bio for a while . I ran out so I was feeding them with just compost tea up untill 2weeks ago since then iv fed them milk mixed with water ph'd to 5.5 200ml to 1ltr of water.
I'm heading into my local grow store tomorrow . I will pick up a soil analyser .
Also what nutes showed I pick up while I'm there?.
Can you please send me another link
I can't seem to open the one you have posted.
Iv been doing much research on the shot hole thing and can't seem to find anything.
Thanks for the help it's much needed

Roots need more air than leaves do. So you are on the right path. Often one can use perlite or some other material to open up the soil even more. Chemically though, in a soil, we have to get the relationship of Ca to Mg high to open up a soil. These guys will explain it a lot better than I. Basically you want around 80% Calcium or even a bit more, to get top quality and top yields of your chosen crop.

 
Any ideas anyone? Newb here. It's a rdwc ph always between 5.8 and 6.4 I use technaflora recipe for success while suplementing Cal mag hydroguard for root rot using led lights. For some reason all the pineapple express in my system are messing up but candy kush is thriving I don't get it. Any help appreciated

how old are they,that 5.8 ph seen low to me lad,lowest i go is 6.5, all ours get water ph7 neutral water,only drops for nuit feeding.trial and error mate just try raise it and see what happends
 
They are nearing 65 days from seed. I messed up in the beginning and let them stay in preveg too long. So it stressed them and when I dropped em in the system they all came back except for the pineapple express . Bottom pic is candy kush and it's thriving. I've read in hydro systems to keep it between 5.5 and 6.5 but some say 6.1 others 5.8 to vest absorb nutes idk total newb lol.....

ha i have pineapple chunk on the go,she like a neutral water,i did drop the ph at the start but she went yellow,so i just let her have water,she quickly went green agian and my nuits with the cal/mag drop my ph to 6.3 i let her soak that for two days and watet then for the rest of the week,i have red that pineapple strains are nuit sensitive,loved a flushing out boomed out after it she did so i lollypoped her after for some major bud sites
 
Yea I noticed pineapple is nutes sensitive the leaves turn yellow so quickly and it being an auto flower it's so unforgiving. The candy kush is fine though so I hate to admit but I've bden focusing on those plants more than pineapple. I orb won't even yield more than a half oz off each pineapple when it's all said and done. I might have to do a quick flush. Problem is after 2 months a circuit blew and all power in room is out. I have been having to bring power from other rpoms with extensions so yea all types of shit for this newb first go ugh

What are these pipes? Do they feed water or just air? I'll take look at the tread now.
Are they just small open pipes or are they connected to something that pumps the air though?
Also nutes I am using now
Sea weed extract biobloom and bio topmax.
