Hi,

Been looking through the curtains at the site for a while, great place, lots of info and finally decided to give it a go.

Have a small problem with a couple of our plants, think it could heat stress, maybe a nute deficiency as well and was hoping that someone could help.

E-indoor or outdoor Indoor
E-soil, soilless, coco, aero, or hydroponic Soil
E-specific medium 10L Pots
CSL-Soil type/brand Bio Bizz All Mix

SCL-Anything you have added to the soil Bio Bizz Bio Grow Organic Plant Food - After 2.5 weeks (have had 1 feed with this)
SCLR-Soil or slab runoff pH Unknown
E-Water source Tap
E-Source water pH Unknown

E-Age of plant 3.5 weeks
E-Type of fertilizer
E-Rate of application
E-Lighting source and distance from plant 400W HPS - 38cm/15inches
E-Air temperature 81 deg F /
E-Air % Relative humidity 35
E-Lighting schedule 18/6
E-Type of ventilation your room has 4" Fan

I know I need to get a ph testing kit and will be doing so ASAP. Looking through other threads in this group, the yellowing on the bottom leaves looks like it could be linked to heat stress when we switched from the fluro to the HPS and those were some of the only leaves around at the time. They were under the fluro for about 2.5 weeks and have been under the HPS for about a week now. Have a 4ā? extractor fan in the tent (Bud Box 75x75x160) as well as a fan blowing air across the top of the plants.

Iā??m sure all you people know what itā??s like on your first grow, would be very grateful if someone could put my mind at rest as to what could have caused this. None of the new leaves that are coming through are discoloured, only the bottom leaves on a couple of them.

Thanks.
