Ak47/48, Leafs curling common ?

[Merfolk]

Well i was just going over some video tutorials, and its just funny that my plants are showing some signs ( was going to post in a day or two, to see if its either under watering or over watering ) But i came across this video, and wanted more input!

84f was the highest temp is the room, canapoy is about 3 ft away from 1000 watt HPS bulb, got a fan between the plants / Light to help with heat... i am pushing air through the 1000 watt.


I am Feeding 2 times a day, 12 hours apart - Medium is rockwool cubes mixed with hydroton at the bottom.

Could i feed 5 times per day? is it needed? growth is good - But im wondering if im under feeding?

if you are in rockwool you should do three times a day or every 8 hours your shots do not show any singns of harm or overwatering, maybe a bit locked up with nutes but just set ph at 5.5 and flush a couple times, rhen back to normal. the steams looks a bit purple showing lack of K.

Yes, heat stress. I have the AK. Read this thread. You will be surprised.

Beware of 1k lights running hortilux bulbs

How does one know the difference between a Hortilux and one that isnt? i didnt buy my bulb from a store.

Its the EYE brand of lights. If it was very expensive it may be one. Look at the bulb, it will say. They put out more lumens than a standard HPS. Increase the distance of the lights from the top of the canopy and see how they react.
