Indoor Help a Noobie anybody?

[billybunter]

Hi Folks, Need a little kind help..

I'm running a tent setup, 250w hps, all mix, with grow and bloom fert. On day 37.

Discovered a slight issue today with one of my girls. I have 2 Fast n' Vasts on the go, one is fine with other larger of the two is kinda pale looking in general with the bottom leafs looking like they have a meg def.

I've been feeding every 2/3 days, not overdoing things, just 1ml litre bio grow and 2ml litre bloom. Temps and humidity all norm. PH buffered in soil.

A couple of the leafs have also turned completely pale yellow almost fully cream in colour, the rest of the plant is looking ok but this patter in starting to appear further up the plant. This is worrying me a bit.

Any help is appreciated. Peace.

What size pot are they in and are you letting them dry out in between waterings. Are you using Gen Organics? Are you using cal/mag?

 

[billybunter]

They're in 10L pots, I believe to be making sure they've dried out, been feeding every 2/3 days when top soil dry, pots light, using bio grow and bloom only, not using cal mag.

Just supplied a shot of epsom salts 1 teaspoon per litre until run off, upon reading up looks similar to a nitrogen def also. I guess time will tell.

At 37 days I would go full dose of both grow and bloom.What your feeding is for young seedlings and is not enough for your plants now.Thats why the leaves are a light green because they need more nitrogen along with the other nutes.I would use some cal/mag at this time to prevent cal def.

thanks namvet, I appreciate your assistance, I've fed them them salts and both plants took around 1.5L at run off so I guess I won't be able to feed npk until the soil has dried out in a few days time (?)

What is a full dose? Should I bump up to 2ml grow and 2ml bloom?

 

[namvet25]

A full dose is what ever the manufacture states on the bottle or feed schedule.

If you are using BioBizz it is normal for them to have a MG deficiency as they move into flower. The epsom salt should help you can foliar feed it too for faster absorption. If ussing BIobiz all their measurements are per liter. So it maybe calling for 2 ml a liter not 2 ml a gallon. Only guessing it's Biobizz because of the allmix, more info and whole plant pics might help. Thanks!

OK well thanks for the help people, it's still unclear as to whether I have an N or Mg def, being my 1st grow it's defo a labour of love, not to menation constant negative earhole from the wife, just annoyed I have issues 5 weeks in when I was doing so well, anyway, I'll keep pressing on. Furthermore, last night I administered liberal epsom salts via soil watering and this morning gave an all over npk feed with the empahsis on the N (last feed was 4 days ago, is this too long for a 5 week old auto?), I suppose my main fear being my first grow is to overdo it, there's a few horror stories on the net! My aim since the start has been to keep-it-simple-stupid, fingers crossed!"Munch..munch..munch
