yeah listen to mal he knows it all. whats wrong with his plant mal? hows he fix it then mal? i dont think the leave are burnt from the cfls. it hink you need lower ph and the mg nutes are too much for your plant some strains dont like it i know this cuzzi am unfortunently growing in it now also
Hey chitown, I'm sorry to be a bit brash and arrogant there but the advise being given isn't sound. When we talk about pH we're talking about the plant's ability to absorb nutrients. Under standard conditions 7.0 is neutral and for soil this is the ideal range. However, MG's soil is acidic, in the 6.0 range so if you give it water with an acidic pH level, you effectively multiply the acidity which is going to lock out vital nutes. To level out the pH in MG, you need to water with an alkaline rating to level out the soil acidity.
As for whats wrong with the plant, that could be a number of things and yes it could easily be heat. CFLs don't put out a lot of heat but if the grow is enclosed the ambient heat does rise quickly.
Before considering all the possibilities we need to make sure the basics are covered. The plant is being watered only once a week, the pH of the water is alkaline, the soil is ammended so it's 75% MG and 25% Perlite, the temperature never goes over 80F, etc, etc
