New Tank, Need Help With Fixing Deficiencies! *pics*
Hi guys, I'm new here but have been reading for months. I just got into planted tanks and purchased mine 9 days ago. I have no fish and am still cycling. I'm running into some problems and could really use some help from some experts around here. Here is my set up.
Tank: 25 gallon
Light: Coralife fixture 1 65w 10,000k daylight fluorescent 10-12hrs/day
Filter: Aquatop CF-500 canister
Substrate: 50/50 fluorite black and fluorite black sand
CO2: DIY 2 2 liter bottles (hooked up 3 days ago)
Plants: CARDAMINE LYRATA, ROTALA ROTUNDIFOLIA, HYDROCOTYLE VERTICILLATA, LUDWIGIA GLANDULOSA, LILAEOPSIS BRASILIENSIS, HYGROPHILA CORYMBOSA 'SIAMENSIS', LAGENANDRA MEEBOLDII RED
Ammonia: constant 0.25ppm (Haven't cycled far enough for nitrites and nitrates yet)
Ferts since day 1: Flourish tabs, Flourish Excel (no longer using since I added co2 3 days ago)
Ferts since I saw deficiency around day 5: Flourish, Nitrogen, Potassium and Phosphate
My problems are that the Meeboldii has brown on the leaves, the Hygro also has some brown and some of the tips are curling, the Hydrocoytle has some brown and some leaves turn yellow then become transparent. Before I added the NPK the Cardamine and Rotala also had yellow-transparent leaves but they have gotten healthier.
Looking at charts on deficiency my best guess was that I was lacking in N and K. I also thought Iron but some charts say that old leaves stay green while new growth is yellow while other charts say everything turns yellow so I was unsure. After taking the pic of the hygro without flash I am starting to think I should have picked up a bottle of Iron. I can't seem to find out info on brown leaves though.
Any help would greatly be appreciated! Thanks for reading.
