ok I didnt even look at the pics. if you are doing 1 2 3 with clones then your burning them. seedlings and newly rooted clones should be getting 1/4 - 1/2 strength nutes. When I was using the 4" blocks I didnt go full strength till I saw roots. Read Latewood's Legacy at top of page, that man knows his shit and there are many peeps who have switched to his line of thinking myself included :thumbsup:

Now I'll go look at your pics and I'll edit if wrong.

ok I'm back for a couple reasons,
1) that RW looks MIGHTY wet!! that stuff hold water like a s.o.b.
2) either get some or make some block covers. got any spare b/w poly laying around?? 4" square, hole in middle with a slit ...... Tada!!
3) what is your PH at??
