Yellow tinging

[Willie72]

Hi there folks, looking for a bit of help. I'm having another bash at growing after my first grow being a disaster.

I am growing a Northern Light in a mix of soil and perlite with Royal Queen easy boost organic nutrition mixed into it.

My grow light is a 300 Mars Hydro light and I am watering with ph balanced at around 6.5 with Royal Queen easy grow booster dissolved into it. My plant is developing a yellow tinge around the edges of the lower leaves, the plant is around fifteen days from sprouting. Anyone got an idea what is wrong and how I can remedy it?

Cheers in advance.

I'd get a couple opinions, but in my opinion that is pretty normal, and overall that plant is healthy and looking good for day 15.

In my experience, the first couple sets of leaves in a lot of plants get a little wonky in color, or shape, or both.

If the new growth looks healthy at this stage, I would keep doing what you're doing.

Cheers fella, I've done a bit of looking after I posted this (should've done it before) and was beginning to think it might be magnesium deficiency and looking for as organic remedy as possible as trying to stay away from chemicals as much as possible. Just a bit para after my first attempt being such an utter disaster.

All good man, it's best to ask when not certain. Hopefully a couple more people stop by to throw in their 2 cents, but the more I look at that leaf, the more normal it looks :smoking:

Mg def is noticable in between the veins on the leaves. So it doesn't look like that to me, but let's see what other growers say.

The newer leaves appear to be yellowing around the edges and especially badly at the tips. Any advice in cause or cure folks?

- she looks a bit cooked, maybe too rich for seedlings as is,.. also, I see no info about pH... water, any nute solutions, and most important, in-pot pH... You'll need a proper probe for that, not a cheapo unit so beware of those! The Accurate 8 soil pH probe is a decent unit for the $,... run-off is bollocks for pH especially with heavily amended mixes like this,....
problem is what to do next hinges on that pH info,....

Cheers,

My nutrients have been a mix of royal queen organic in the soil itself and royal queen growth booster dissolved in the water and I have been ph-ing the water to around 6.5 but not got a soil probe. Might look into that.

Would it be worth watering with plain ph-ed water?
