[StevetheGrower]

Hello guys... i have a problem with my girls 2 different seeds same problem but i think it is a magnisium problem here some info:


My plants are feminized seed one from RQS called (SPECIAL QUEEN) the other one is Barneys (Mimosa Evo)
Indoor Garden 3x3 4inh Exhaust fan ,plus 2 fans circulating air inside the tent 3gal plastic buckets

I am growing in coco coir 70% 30% perlite under a 300watt led Mars hydro brand at 40% dimmer not full... height above canopy around 70 cm
My plants are almost 4 weeks old veg phase and the problems started to appear about a week or so ...
I am using Advanced nuts base Sensi grow vooodoo piranha and tarantula etc..etc..
First week i gave them only ph water 6.3
Second week i introduce them some bacteria from voodoo1ml/l and piranha1ml/L and tarantula1ml/l plus i was adding some cal mag 1ml per liter
Third week i started to give them the main nut Sensi grow for coco about 1.5ml/L
And now fourth week it started to show some deficiencys on the leafs getting yellowish so i gave them a big dose of cal mag 2ml/l

Yes, thats magnesium deficiency... Start sooner next time with Mg when u grow in coco as its far more demanding.
U can do also foliar calmag. PH same as hydro requires.

Growing healthy plants is a balance between light, water, and feeding. What you're seeing is the beginning of a condition called "tips & stripes." It's what happens when your light is too strong for your plant's ability to uptake certain nutrients. You're right that magnesium plays a part. The easiest way to fix it is to turn down/move up the light. Or, you can try to figure out the "right" level of one or more nutrients.

You need to pop over to Coco for cannabis. Get the book and study a bit. Will help you big time.

I'm not a fan of changing multiple variables at once. I'd manage this with the light. (Also, you've just given the plant a ton of calmag...)

The problem of changing multiple variables is it's difficult to know which one caused a change or if they interfered with each other. There's a chart of nutrient interactions known as Mulder's Chart. It originated in the 1950s, so there's lots of information about it. Calcium and magnesium are antagonistic.

let them go a bit longer in those pots before transplanting and flipping to flower..
say another 10-14 days..
