Healthy vigor or deficiency?

Hi RIU

Concerned father of two teenage girls (day 47 from seed, day 10 flower under 400W SonTAgro)

In the picture below, is the yellowing around the central parts of the new leaves a sign of healthy vigor or a deficiency in something?



Your input is greatly appreciated...
(additional details in my very long winded journal, linked below)

From what I see ...now ...is looking good, but just like us oldies we need a boost too,
so look to some foilar calmag every 5 days ..half a teaspoon to a pint hands sprayer with warm water and spray minimum 1x per week or like me every day ..lol

Thanks Vostok

I agree totally, I've been wanting to foliar spray SOMETHING on them.

I don't own a Calmag supplement. I read somewhere that you can dissolve some dolomite lime (filter out the stuff that doesn't dissolve) and use that as a calcium/mag foliar supplement? I have also have Seasol (a kelp extract) which has 458mg/L of Calcium and 972mg/L of magnesium.

Do you think either of those will do the job?

Seasol will work fine. Plus it has enough extra trace elements that plants will love like chlorophyll .

Thanks, I wouldn't call chlorophyll an element, but I will take your advice and hit em up with the Seasol
