Bottom leaves yellowing..

Leonida said:

hey guys,

This northern light is at his 10th week from sprouting

Under Mars hydro TS 600

since few weeks the leaves yellowing is spreading from the bottom, why do u think it can be??

I water her every 2 days (it's a small pot, 5L) and I give her feed three times a week, advanced feed for flowering phase

ADV Nutrients - Sensi Pack (pH Perfect)

The fertilizer kit Sensi Pack by Advanced Nutrients contains basic nutrients for growth and bloom, root stimulator, bloom booster

I read it can be N lack but I don't think so as I'm feeding here like any other plants and never had such bad yellowing..

She had a mild thrips infestation, but now it's going better

Calmag should pull it out of lockout, but it definitely needs nitrogen

How much do you feed from each bottle per feed? Do you feed the same bottles every feed?

Also what medium are you using?

I follow the instructions, usually from 2ml to 4ml X liter 2 or 3 time a week, I don't keep the solution in the bottle for more then 1 week.. I put all the one should go in the same bottle mixed..

Magnesium deficiency. Mix up some epsom salts with water. I use 1/4 cup per 5 Gallons in the water. Or you can do a foliar feed as well. They green up almost instantly when you spray it.

Magneisum lets the leaves uptake nitrogen. Thats why they are yellowing. Some will come back but none that are too far gone.

Throughout the week when feeding... do you re-check ph? I promise 9/10 times it changes. I've fed that way before... but the ph changes as it sits.

If left in a bucket with a pump and air stone.. it may remain stable.. but I wouldn't quote my high ass on it. I'd look it up if that may be a possibility.
