First grow, think i have bad mold problems :(

[growerdude]

Need help, suggestions/comments would really be appreciated, pretty sure its mold/mildew. Pictures below. First grow, 23 plants from clones, currently nearly 5 weeks into flowering. Ive had problems with high humidity for a while, up until a couple of weeks ago it was sitting at about 90-100% with condensation for about half the day, over the course of a few weeks. i have managed to get that reduced a bit so things are slightly better, but cant fully fix it until these plants are harvested/space cleared in the room to change things around, because they are just too big so no space to move in there. Here's the form details:

E-indoor or outdoor---indoor (but in a wooden garden shed, so slightly more exposed than in a house)
E-soil, soilless, coco, aero, or hydroponic---soil
E-specific medium
CSL-Soil type/brand---BioBizz All-Mix BioBizz All-Mix Soil 50 Litres - Hydrohobby Hydroponics UK
HCL-Hydro/aero/soilless system type
SCL-Anything you have added to the soil---Nothing
SCLR-Soil or slab runoff pH
E-Water source---tap water
E-Source water pH---7.5ish
HRT-Source water EC (if hydro)
E-Age of plant---clones planted 8 weeks ago, flowering for 4.5 weeks
E-Type of fertilizer---Canna Terra Flores, Cannazym, Canna PH down pro
E-Rate of application---Included with every watering from pump + irrigation reservoir, once per day
E-Lighting source and distance from plant---2 x 600w HPS, currently about 50cm from top of central plants
E-Air temperature---day (lights off) 18c, night (lights on) 26c
HD-Reservoir temperature
E-Air % Relative humidity---day about 90%, night about 70%
E-Lighting schedule---12/12, on from 9pm until 9am
E-Type of ventilation your room has---passive intake, filter + extractor fan, 2 x circulation fans
TR-Did you pre-soak your media in pH corrected solution?

Most plants are about 1m+ height and look ok-ish with a couple of exceptions, like the highest leaves were probably getting too close to the lights, which i think explains some of the "warping" in a couple of the photos? But i've raised the lights a bit now. Because of the high humidity problem ive had mold forming in a far/seperate part of the room and seems like on the leaves, maybe some buds as well. the 100%/condensation problem is better now, but i know its still too high. The mold in the rest of the room has been killed with mold killer/bleach and not reformedand ive been spraying as many of the plants as i can get to with Cannacure, but think i might need somethng stronger so i can hopefully get to the point of harvesting without losing them. here's a bunch of pics, some are a bit shit though, but if you look at the leaves etc you can see what im talking about

Well that sucks....

Mold and mildew are products of not enough air flow.... Might want to get yourself a bigger extraction fan and instead of a passive intake, get an actual fan/blower to push new fresh air in....

And at the same time, if you have them outside in a garden shed, and surrounding humidity is 100%, your probs will probably persist.... Not only that, a majority of your larger buds are going to suffer from bud rot if humidity isn't controlled as of yesterday....

I feel for ya....

Forgot to mention, airflow has always been a bit of a problem. The extractor is definitely sucking a decent amount of air though when i have checked it by removing the tubing from the filter. However when checking the ouside of the filter i cant really feel much suction at all. i was hoping i could improve this after harvest. So what could be done? A dehumidifier i suppose?
