Progress?

I've noticed that the very tippy tip tips of the roots are kind of shriveling and turning brown, besides that they look nice and happy.

I would love to know how old these are. I know they are well over a month old. Have I stumbled upon the world's slowest growing strains?

Overall, for those of you who remember the pictures from my last post- How is my progress?

PH Drifts from 5.5 - 6.1

I haven't added any more nutrients in the past week. I had it around 250, and It's raised to 320! Ph and PPM rises slowly every day.

Wouldn't you think by their age and size they could take more nutrients? Is it possible that the couple of inches in the bottom of the flood tray (which is aerated) could be evaporating water, and leaving nutrients which is why the ppm goes up, and its not that the plant is using more water than nutrients?

Also, the first set of leaves at the very tips are browning, I don't believe its nutrient burn, but may be heat stress from early stages.

Tell me what you guys think!

Here are pictures of the roots, also the last picture is of Mr Droopy who is supposed to be dead.

I.. uhhh you know how it is, old folks can't remeber yesterday let alone some pics you posted, why not just keep it all together in a journal, the key word being a ?? VV

Here are two shots from 14 days ago

Been saving up water for the reservoir change. 10 more gallons to go

In the meantime, I have shut off the water pump, and have been manually watering them with pH corrected water with no nutrients (in hopes in would reverse any potential nutrient lockout)



Here are some some shots.

These are taken 8 days after the pictures in the beginning of the post, 22 days after the seedling shot i posted later.



Are they growing guys, what do you think?
Let me know!!

just clean h2o for them, they are seem to recovering, my suggestion is to keep the h20 clean and balance with no nutes, until they show they need it
