Plants Dying

Bought a couple tanks in March, a 55g and 30g(36w x 12d x 16h). Got the 50g going immediately, and have Vals, crypt, and sword plants under 4x 13w 5000k CFL mounted horizontally, 10 hours light. Plants growing well. The 30g I had 3/4 water and various plants ( mostly vals) floating under single T8 Aqua glow light at 10 hrs/day. April 7 decided to start 33g with PFS and planted tank (and seeded filter)...plants growing. Apr 14 switched 33g to 2x CFL 13w 5000k mounted horizontally. Plants doing ok. Added couple sword plants week or so ago. Now plants seem to be dying off. WC was approx 50%/week but bio load very low with 2 Kribs and approx 8 guppies. Have now reduced WC to 25% per week and upped light to 12 hrs. Is it possible too much light and should I reduce light to 8 hrs? No ferts are added. Oh yes, added an air stone last week too just for surface agitation. Filtration Fluval205. Any ideas or suggestions? Thanks everyone.

Do you have pictures? What substrate are you using? Are the leaves turning yellow or melting away?

Please post good quality close-up photos of the new and old parts of the plants.

Also, the number of tanks and what is going on with them is confusing the way it was posted.

So you have four tanks? A 55g, a 50g, a 33g and a 30g ?

Yes please do, so then we can all go "OHH - AHHH" and marvel at zapins acute knowledge of plant deficiencies. Then siphon his knowledge into our own heads

Sorry for confusion. I have 2 tanks. One is a 55g and doing fine. Second is a 30g and that is where plants seem to be melting away. Lots of Val leaves floating around. New Swords have leaves starting to look thin. Substrate is PFS in both tanks, and both have MTS (snails). WC water for both tanks from barrel; heated with aquarium heater and aerated with stone and some Nutrafin Aqua+.Water is very hard (400ppm) I think and pH 7-7.5. New Val shoots are lighter green colour and recently I have not noticed any new ones. Hope this info helps.

Not enough light in there.
CFL need to be mounted virtical.

The shortest distance between any two points is a straight line...in the opposite direction...

By dying I assume you mean the Sagittaria grass looks like it is dying? This is from trimming it like grass. When the leaves are cut they tend to die back rather than seal off like real grass. You can trim it this way, but the plant doesn't really take well to it.

The sword looks alright. I see one leaf that has a few spots on it which may be very early potassium deficiency.

Tnx for the reply. There are actually 3 leaves suffering on the Sword. I have not trimmed anything in the tank...that is why I am puzzled to see so much floating dead leaves etc. I am going to go longer between water changes ( if testing permits). Just noticed baby Kribs in the tank so will try not to disturb things too much right now.

Congrats on the fry! Raising kribs is loads of fun.

I only see one bad leaf on the sword. Any chance you can get a close up shot of the other two and the dead floating leaves?

The brown leaf at the back of the plant there, is it possible to cut it off and take a photo of it in full view? It looks like the tip has died and the leaf is dying back towards the stem?

If so this may indicate a nitrogen deficiency rather than a potassium deficiency.

Take a look at the nitrogen deficiencies in other plants to see which one it matches more closely: www.deficiencyfinder.com
