Hey All...
I'm a new grower and about 20 days in the veg state (18/6 H of light). Already encountering my first problems... My indoor grow area is about 4sq.ft (1,5 sq. m). The temp flactuates from 71F to 77F (22C - 25C). Humidity is 58% - 75%. The water pH level is 6.5 and the soil pH about the same. I am using BioBizz nutrients.
As you can see from the pics attached some of the leaves firstly demostrated some "indentations" on the top parts. Like small inward dents. Then some of the edges curved upwards and now some leaves appear brittle and dried. They feel like paper... I researched the symptoms and thought that it is heat stress, so I moved away my 400W MH lamp (from 1,7ft/52cm from top leaves) to 2,2ft/70cm resulting in slower growth. I don't know what else to do...
Do you have any ideas? Is it indeed heat stress? Or is it nutrient burn?
Any help from someone more experienced would be appreciated.Thanks in advance!
