Hi everyone.. First time hydro grower here. Needing some expert advice.


Specs: polyfill growing medium
Gh 3 part nutes
Constant flow gravity fed DWC
Bagseed


First issue:
I'm needing some help identifying the male plants. I've read the documents and looked at the pictures but still not quite sure. The pictures are below.


Second issue:
Discovered some black mold in the reservoir on a rubbermaid label that I forgot to remove. Also found a black ball of what i assume is mold on the roots. I've been using h2o2 since the beginning, hopefully that will control it. Is it safe to use a fungicide to control the reservoir mold? Please suggest anything else you can think of.


Third issue:
It seems growth has really slowed down lately. Could be nutrient lockout attributed to the ph of 7. However, the ph has been at 7 throughout the entire grow... Tried vinegar to lower the ph but had an adverse reaction..(wilting and foam on the water at one point).. Can't afford ph down at the moment. Looking into "super triple phosphate" from the hardware store but I'm afraid to add anything (especially during flowering) after the last time i laid the plants down with vinegar.


Fourth issue:
I'm using the 3 part GH nutes and about to run out. Too broke to buy another round of nutes so i'm considering a poorman's nute solution(miracle grow, epsom salt,calcium nitrate). Does anyone have experience with poormans's solutions?


Fifth issue:
Hydro has really turned out to be a hassle in comparison to soil. In your opinion, is it really worth all the extra work? Does it get easier and less costly with experience?


Misc Questions:
1.Is it safe to spray seltzer solution during flowering? (mold concern?)
2.Is it safe to cut the mold from roots?
3.Why are my roots the color they are?
4.What is the maximum amount of h2o2 that can be added?
5.Mold found in tank.. does that mean it's in the polyfill growing medium too?



Any comments or suggestions welcomed! Thanks!
