PLEASE HELP MY PLANTS :(

[amjadabas]

hey guys,
this is my 1st grow and i've been seeing a few changes with leaves color which could indicate something.
- indoor
- soil
- veg stage (one month old)
- 400W metal halide + 2 X 125W CFL + 2 X 85W ( 4 plants)
- temp 27-28 C
- humidity 35-40%
- Water EC - 35 ms/cm
- Water PH - 6.9
(i did not check after adding nutes)
- watering every two days (when soil feels dry)
- feeding flora series and vodoo juice ( with almost every watering, but i flushed a week ago and the problem continued.)
ignore the whitey powdery things on leaves when you see them, it's sulfur spray to treat of what it seemed very mild powdery mildew two weeks ago.
just focus on the leave color itself.
please help

I'm not sure, someone more experienced can chime in. What I noticed was in the 2nd to last pic in the brown pot that plants yellowing starts on the bot. I think calmag will fix that, 1/2tsp per gal. Also, I feel like that's a ton of light for just 4 plants in veg. The 400 mh alone is good enough, I'd save on the power. Unless your room is bigger than 3x3?

should i flush first again ? it's possible that there is a lock up in th roots and they cant absorb it well ??

 

[Mean Gene]

Dont flush again. Youre over thinking this. If your top leaves turn yellow...amd i meam TOP LEAVES turn YELLOW thats a zinc deficiency. I dont see that here. What i see is what kooms said. Too much light. You are over powering your babies. Remember during veg you need light but during flower more light is better. Dont over focus though. Sounds like too much light on top of your plants. Check the forums here on lighting and space. You will learn a lot. Happy growing.

i'm thinking towards magnesium deficincey or nitrogen, what do you think?

 

[PKHydro]

Mag Deficiency . I can't see it being too much light there's 2 1000w MH in my veg room. And I don't get anything like that.

what size pots ?
could be calmag but 6.9 ph and why would you not check ph after adding nutes ?
aim for 6.5 ph and no good testing ph before adding nutes to the mix

pot size is 12 lit
i checked ph of the flushed water, it was 5.9-6.2 could this really cause a lock out ?

could do mate work out your run off and upp the ph to try get it to 6.5 mate 5.9 imo is what could be the culprit what soil u using ?
sorry if u already said the brand but i only use canna terra professional

 

[smokeyjoejoe]

It's not nitrogen that would turn your fan leaves yellow so don't worry about that I would get yourself some epson salts that will sort it out it looks like a magnesium deficiency you need to get your ph in between 5.8 and 6.2. I use 1teaspoon for every 20 litres and use it every feed from veg to harvest and never get mag problems again

 

[smokeyjoejoe]

Doesn't look like light bleaching that will look the same as if you got bleach on your clothes you need to test the ph after you have mixed everything up no point in doing it before as your nutes adjust it once there added

i'm using All Mix soil from biobizz
with EC of 2.6 m/cm and PH of 6.5

 

[Thc247]

- Water PH - 6.9

make your fucking mind up 6.9 or 6.5

so basicly flushing and controlling EC and PH and then adding magnesium with the basic feeding program of floraseries. correct??

 

[amjadabas]

6.5 its the ph of the fucking soil how it's written on the package. ( and EC of 2.6 m/cm)
the water that i'm using is 6.9 PH and EC of 35 mm/cm ( if we conver it to m/cm its about 0.3 m/cm.)

 

[Thc247]

6.5 is the ph of your soil but the water is 6.9 going in before nutes so what is the ph of the water with nutes added ?

 

[Thc247]

ive never gone by ph soil on the package its all down to what u give them and ye i know soil has buffers in it and all that malarcy but test ph with food before feeding and test run off and post results

 

[amjadabas]

do i have to flush now with RO water ?

 

[smokeyjoejoe]

Just ph your tap water to 5.8 and flush, how long have you veg your plants???

I think you are drowning the plant. It needs to breathe. Stop putting water on it and let the plant go until the leaves just begin to wilt. Then, flush the plant with pH'd water, set to around 6.0 if you are in dirt, that should off set after one day. Then, continue feeding as normal, but space out your watering. If there's water nearby, the roots will get it. It needs oxygen just as much. The discoloration tells me its having a tough time distributing nutrients properly which is often a case of over-watering.
