a problem that i cant quite figure out hydroponic strawberrys
Ok I am growing albino ever berrying strawberries in an flood and drain set up indoors under 400 watt hps.
light is on 18hours 5am-11pm flooding 2times a day at 12noon and 4pm for 15mis a piece.
they have been growing about two weeks in ph corrected water.
week three added 1/4 general hydroponics nutrient to my 15gal reservoir three days or so later the water had started to smell like a fish aquarium and there is white foam on the top of the water.
I flush the system and cleaned with store grade 3% hydrogen peroxide refilled my reservoir with fresh tap water and nutes to a 6.0 over night the ph jumped to about 7.3
so i dropped the ph back down this time dropping it to far about 4.8.
i said to my self i am not going to do anything because the flood is till the next day at noon and i wanted to see what happened because of the weird flux in ph i was having
when i checked the ph before the flood at noon the ph had risen to a perfect 6.0 and after the flood it was the same. now i checked the ph again before the next flood noticing that weird smell associated with white foam along with a jump in ph up too 6.4 by 4 pm then around 6pm i checked my ph once again noticing it was about 6.8 not sure what is going on here...
i have good air at the bottom of the bucket my reservoir & temp is about 58-60*F room temp is 78 during the day and 64* at night
my tap water is about 80ppm and ph is around 9.7
also with 1/4 strength nutrient my ppm is about 390 to start with 5ml of super thrive.
not sure what this is from so question being is it the quality of my tap water?
growing algae in my bucket?
or other problem/disease?
also not i think i burnt the edges of leaves from keeping my light too close to the plant but is it possable that the edges around the leaf turn brown and crispy from not having the system flood enough because i dont think its the nutrient's because the ppm is so low but it also could be due from ph flux some input on this would also be helpful
also you can click on the pictures and go directly to my photo bucket for more pictures if needed
i hope to post pictures really soon here of the water with the foam.
please forgive me im a newbie getting his feet wet... thank you in advance to your responses.
