Very impressed by the 2x2 grow, with 16 hours of light a day, the light comes on at 4am and off at 8pm.
I will stop calmag next week because the epsom salt I use in the soil will be active now.
Temps are cold in the morning, a few degrees lower than day temps, I will turn on the heater today, Ireland is cold in February, but the plants are well established now and show no signs of slowing..
It has been 14 days since 12/12 and they where late flowering, so Lowered the night time humidity to below 50%... this seemed to trigger flowering overnight.
I swapped the light to the more powerful Migro Aray 2. This will power the plants through to harvest, the LED is very powerful, I use the Aray 3 and 4 in my other grow diaries.
Heavy defoliation this week.
Added calmag and lowered bio grow, flowers require calcium and magnesium in late flower, the moment they start to change colour or get new brown spots, I assume they require it.
Hi guys, Is anyone using Cal Mag for a bloom booster only? I think I should have started using it 2 weeks ago to prevent the brown tips, rest of leaf is perfect.
4th-5th week of flowering, right at the peak of this stage. But not after, need for nitrogen ceases.
You should use Cal-Mag during the vegetative and early bloom stages and during the halfway point of the flowering stage, you might want to reduce the application to 3 ml/gallon, to avoid adding a toxic level of nitrogen as nitrogen is the most sensitive to toxicity of all the minerals.
Calcium, magnesium, the grease on the wheels that makes everything work.
