my plants need help(pics with full info)

well hello there world :)..

need some help before this problem persists.

ok so im on my week and 3 days of my new plants and there still on the seedling feeding schedule(they have 4 leaves plus 4 more coming out under neath them)

the thing is one of the plants two leaves got burnt/brown on the tips and all three have kind've regular green with a tinge of lime color on the leaves.

now i wanted to know because of the leaf count if there in vegetative stage now and thats whats causing the nutrient problem "looks".

some info: i have a 2"W X 4"L X 5.5"H cloner tent with

3 39w 6400k HO sunblasters 3Ft T5 CFL's

18hr light cycle: 10AM-4AM

its a custom hydro Drip setup which the plants get fed 4 times a day for 15mins

sched: 12pm-12:15pm, 4pm-4:15pm, 8pm-8:15pm,1am-1:15am

regular air circulation:

its a small desk fan that ive mounted on the bars of the tent

sched: on 12pm-4pm off, on 8pm-11pm off, on 2am-5am off

---------------------------------------------

there in rock-wool and when changing the nute tank should i flush the rock-wool also so they get the next nutrients instead of the old stuff in the cube plus the new stuff i just put in?.

i have a bunch of theory's on why its happening i just need to know exactly how to fix it.
-------------------------------------------------------------------------------------------
****EDIT: i also uploaded the picture of my tri-meter readings :)

water: my water has 200ppm at the starting so my seedlings get 360ppm of nutrient added to 6 LITERS of water

-----------------------------------








 
the strain is called "the purps" and its a Sativa / Indica Hybrid..

im guessing the lights are 6 inches above the plants, and there not directcly under the lights because there strip CFL's
 
thanks a lot!!!...

my room humidity right now is at 57% so i changed the fan cycles for only an hour at a time a few times during there light cycle. i also raised the lights, they were high when they were first sprouting but because they stretched i thought i might put the light lower so they wouldn't be so lanky.

that article gave me some good pointers and some interesting light cycles for sativa and indica.

never heard of different light cycles for the two types

sativa 13/11 veg, 11/13 flow <--- ive always thought it was 18/6 and 12/12 for everything.

----------------------------------

well i guess i'll see if raising the light and changing the fan cycles does the trick..

1 more thing... should i flush my rock-wool every time i change my reservoir so i dont get mixed concentrations of nutes?

and my plants aren't 2 weeks old yet but have gotten a lot of leaf growth.

4 of my plants have 4 big leaves as you can see in the pick and 2 of them are growing 6 other smaller leaves, ive read its 2 weeks for seedling's but was wondering if my plants just grew fast and are in vegetative mode early?

No problem!
Glad it helped you out a bit, sure helped me out. At the moment I water my girls by hand 3 times a day I keep my temps at 82-83 86 the highest and RH at 40.
I'm growing Bubba Kush which is an Indica in 4 inch RW at 18/6 with 4x 23watt 100watt equivalent CFL's to keep heat down, at 3 1/2 inches from the plants and will Flower at 12/12. at least that's what' recommended from sources to do with this strain... So about the RW I'm not so sure... I give mine 8th of a teaspoon to the gallon of superthrive ($4.95 local green thumb nursery) and water ph'd at 6.2-6.4 for now... so I'm not using Nutes yet. but you don't want to stress them out. Just be careful with them nutes bluephoenix let them get a little stronger.
