Leaf edge curling why???

Ah i see they mention on the next page soil testing in labs, this is another consideration, if i new the exact nutrients in my soil at time of problems diagnosis would be a lot easier. I have always thought these tests exspensive in the UK but have not really found somewhere that dose it, all id have to do is dig up a sample of my soil from the pot and soon id have the exact mineral and fert levels, would point to the exact plant problems with ease. Peace

Then we would have to consider nutrient imbalance or similar, im just gona assume you got good free draining soil and that flushing seems to help but you cant solve the problem completely.

My biobizz hacks me off because i need the grow with the bloom for flowering, if i just add the flowering then my plants can get like this quite easily. More details would help but i like to guess. Peace

BTW this seems like an old thread now, i think my growing has improved a lot since then.
