First time grower - Something wrong?

[greenhousetr]

Hey Guys , my girls are critical 2 + and i ve got 4 girls ;
They have been for 1 week in big containers
Tempreture ; 24-25 C degrees
600 watt plant star osram, from girls about 45 cm (18 inc)
Humidity around %60 - %70
PH 7-8
I am using Hesi Starter for soil, i started to using 1 week ago and i gave them to all less than half strength soil , and i give good ph water . i add water as much as they need i guess not much not less around 4-5 liters for each one (every 3-4 days )
I added magnesium nuts today ( first time )
However , they don't seem very happy to me . something wrong ? what do you guys thing ?

Well yes there is a lot wrong...

So the temps are correct so the heat stress is either due to the light being too close or not enough humidity and also probably not enough air circulation.

You have over done the nutes significantly and should not be adding really much at that age in soil. A good soil blend will have everything they need pretty much all the way through Veg so no need for veg nutes if done correctly. All of your pics show Nitrogen at toxic levels. the third pic is very unhealthy.

You say you have good pHd water but right above it you say you are pHing it wrong. 7 is the absolute top of the range and things start to fail at that point and only get worse the higher you go. 6.3 is much better. In soil you can have good nute mobilization between 6.2 and 7 but closer to 6.3 the better. the farther from 6.3 the worse things get. After 7 many things start to fall apart.


Make sure that the dry out between watering. Best in veg is to wait until the leaves start to droop to show signs of lack of water. that will spur strong vigorous root growth and make for a faster growing healthier plant that will have larger flowers in bloom.

Best of luck to you. I hope you can get these straightened out. I wait till they are dry then do a full flush to try and rinse out all the salts in there now.
