Long time lurker first time poster.
New to growing and enjoying the experience. I have tried to identify the problem but have drawn a complete blank. I have checked the great resource on the forums and read through a lot of threads but cant seem to find an exact match, especially with the same conditions and parameters as my grow.
As i said I am new to growing, and after obtaining some rotted cuttings about 2 and a half months ago, i have made all the classic newb mistakes from keeping the temperature too high, to over feeding and not keeping an eye on my PH levels.
However now, i have my grow room at a constant 24°c, i check and maintain my ph levels with sillicone etc. The plants have managed to come through and have been looking healthy despite their bad start.
The problem is now i have brown spots appearing on some of the leaves, at all levels of the plant, it seems to be spreading and getting worse, and i need to contain it and identify what the problem is before i lose them.
Plants are in 45L tubs, fed once every 3 days at this point, 12/12 lights, in days 13 of flowering, PH is 6.4. Planted in MG soil approx 3 ft tall, under 2x 600W HPS light, phillips growlux bulbs.
I've attached pictures showing extreme damage on the worst of the leaves and also other parts where the leaves seem fine. There didnt seem to be any pattern to which leaves were being affected, it was the larger leaves at the top, right through to smaller leaves at middle and lower sections.
if you have any ideas on where i'm going wrong, please let me know, i know the plants didnt have the best start, but after recovering and doing well, they now seem to be getting bad at a fairly steep pace. all help appreciated.
