Calmag shouldn't be given at every feed. Every ten days is sufficient.
Are you watering to a runoff each time & what is the ph of this ?
I would just water with ph 6.2 to 6.5 & check the run off as I think you have nutrient lockout.
Remember your growing an auto & they can't take full feeds like photoperiod plants. Start a diary & goodluck

High bro, I see what the problem is here. Your pH is out of range, you need to adjust the pH with a pH adjuster like Biobizz pH min and bring the pH from the nutrient solution down to around 6
The other problem is that you water to frequently. You want the top layer of the soil (the top inch) to be dry before watering again to prevent root rotting and all kinds of other problems. Next to that reason roots need oxygen too!
Ok so long story short, adjust pH and water only when the top inch is dry.
Enjoy your grow buddy!

Too much light or PH imbalance?I dont know, something strange about the color, the spots on the leaves maybe? suggestions accepted. Maybe I need to add a fan ASAP, or let more air into the tent?
Dimmer is sset to 20% 25% , maybe I should give more light? or maybe less?

My leaves are turning yellow, please help??There is yellowing in my leaves, my plants are 11 weeks old and they are on VEG, but the bottom has started to turn yellow. What is the reason? Could it be that 18 liters of soil in the pot is not enough???

One plant (the one on the right) is going yellow, with brown mottling on the leaves. Both plants have been treated exactly the same.
I’m giving the plant some calmag and extra nutrition after flushing it (which had no effect). Any ideas to save this plant? Worried…

Suddenly, massive problems. Tried a lot already, nothing helped yet. Any ideas what I'm missing?Hey guys, I've been growing for a few years now and something like this has never happened to me. Long story short, as soon as I move my plants from the veggie box into the flower box, they slowly start showing these symptoms (see pictures).
The box worked fine for several grows

Seedling Light-burn or ToxicityHi growers!
Is this Light Burn, or nutrient toxicity from nutrient dense soil?
2 Mars Hydro TS600 lights at 27" from seedling.
PH 6.3 misting soil - RH is 75-80%. - Temp is 77F
No light meter, so I estimate PPFD is in acceptable range despite using 2 lights in 2x2 tent.
