Hey all, just hoping some wise sage can help me with a question regarding my treasures... Here's my info:

Indoor
soil
Random potting soil mix for roses - only thing available
Soil runoff pH 7.5+
Water source: bottled water
Source water pH: 8.0 (treated with organic cider vinegar to 5.0)
Age of plant: 4 weeks
Type of fertilizer: Age Old organic plus compost tea
Rate of application: 1 fert water then 1 compost tea water
Lighting source and distance from plant: 3 65W CFL's 5in. from tops
Air temperature: 85 day / 80 night
Air % Relative humidity: 45-60%
Lighting schedule: 18/6
Type of ventilation your room has: Fan
Did you pre-soak your media in pH corrected solution?: soaked soil in pH 4 solution to lower pH since it was high in the soil i bought.

I'm limited in the options for soil here - the stuff i have has high pH. I tried to lower the fresh soil using a HCL solution before repotting (repotted at 2 weeks old), but soil runoff pH is still quite high. The plants were topped at 2.5weeks old(6 nodes tall).

The new growth since the plants were topped is very light green. They are growing fast, but I think they're suffering N nutrient lockout from too high soil pH. In the pictures you can see the difference between the new growth and the clones made from the tops.

Am I correctly identifying the problem? Is overall lime green growth in an otherwise healthy plant a sign of N deficiency due to high soil pH? or could it be disease, other nute def, etc..? I read its not good to water soil with super low pH levels, so i treat my feed water to pH 5.0 with vinegar. no access to lime, sulfur, humic acid, pH down, or peat moss where i live that i'm aware of.

Pic 1: two of the three plants, with the top cloned from the left plant between them. This is with flash. You can see the difference in color, and i think that waxy look on the clone's leaves is good, definitely not on the new growth.

Pic 2: same shot with no flash - gives you a good idea the difference in color.

Pic 3: the schedule/notes. You can see i tried foliar feeding, and upped the nutes for the foliar feed. In the pics you can see the plant tips just a little burned from that second foliar feed.. didnt affect plant color much - mayyybe a slight improvement...

Thanks for ur help!!
