Issues with Sativa Grow

**sarahnya** · 11-08-19, 08:25 AM

I'm currently on holiday and left partner in charge of tent. Today he sent me the following pics and a couple of the plants have gone pale. It looks like a nitrogen deficiency but I only potted them up into 11ltr pots a week ago and fed 3ml per ltr of oldtimers grow, they were all a deep green before I left. I'm worried something else might have locked out nutrients. I did use a half dose of bio silicon a week ago (praying boyfriend didn't use ten times the amount or something stupid). They are in Terra Canna Pro soil under a 600w HPS.

They all look just fine to me, maybe touch of trace def but nothing major?

I see no signs of N def at all. Id be careful not to overfeed if anything, 3ml per litre is a strong dose, Id be at 1 or 2 if at all. Personally I wouldn't of fed these plants but that's just me

Edit.....
I may of started plant 2 on 1ml.per litre but thats all

Id lower the dose to 1ml oer litre and feed water feed until they start to yellow low down then increase to 2ml and so on.

Are you a hard or soft water area? If soft water get a cal mag spray done at 0.5ml per litre before they flower!

Watch these though coz organic is slow and they will take a while to show symptoms of over feed. Potentially leave them on water for now and watch n wait

Ok so no panic stations just yet then. I will keep them on water for a couple of days, if it gets worse I'll feed a low dose.

Gonna spray cal mag too then we know bases are covered d

Well just to report I'm back today and they look ace. My oldtimers x amnesia haze turned out to be a girl too so I'm stoked. 5 nice looking young plants, let's hope I can keep them that way!

That's good to hear, you can stop stressing now

Not sure why folk spray calmag ,certainly when it's to late or obvious needs arise ,I use calmag mixed into base feed perhaps 3-4 times per grow always stood me well ,prevention rather than a cure ,just ordered another bottle ,the last 1l bottle lasted me 2 years growing 365 in coco
