Plants don't look right, yellowish. (Pics)

stewlounse · #1 (**permalink**) 03-07-2008, 09:38 PM

Hey guys.
I'm 1 day shy of 2 weeks into my 1st grow and things were looking great up until about a day ago.

There are 3 plants I am asking about.
The 1st is drooping badly and has some yellow in the leaves.
The 2nd and 3rd look to be the same with some yellowing.

I've followed the 2-3 day watering schedule. But, before watering I always check to feel with a finger.
No nutes have been added.

The nutrients I have on hand is: "Vigoro all purpose plant food" NPK 24-8-16 (has not been used yet!)
If the other element percentages are needed I can reply with them.

Any suggestion?

Custom Grow Box:

2 - 26w CFL (100W equiv.) Daylight 6500K Lights
3 - 26w CFL (100W equiv.) Soft White Lights
"Emergency Blanket" covering the walls, ceiling, floor.
Jungle Growth soil, pH 6.8-7.0 (measured by me)
72-78 degrees avg. temp with 20-35% humidity.

They are very small for their age, and don't nute or fert this early dude. WAY too early.

Yeah that's what I was thinking.
I wonder what's messin with em.

I'm guaranteeing the culprit is the growing medium. Flush it out and stop using nutes.

I haven't used nutes. I was just saying I have them available.
Or are you saying its the jungle growth soil? It was bought at Lowe's.

I dunno. Thats what happens whenever I used certain soils. Some just seem to be horrible to grow in. Probably depends on whats in them I guess.

I did a search on your soil and unless your using the organic one the nutes in the soil are messing with your plant. Flush the soil through with like 3-4 times the amount of water the containers would hold. Next time make sure you get soil with no nute. The NPK should be 0-0-0. I use Miracle Grow Organic and my plants are thriving.

and the 20-35% humidity can cause you some issues as well.id at least want 45-50% if i were you

Yeah, being a beginner, I completely overlooked the nutes in the soil. Luckily I had some other soil with very low NPK and I took a chance and transplanted them very carefully. They are coming back! Thanks!

About the humidity, anyone have suggestions for raising humidity in a small space stealth grow box?
Also, is there a difference in lighting ...say...on 24/7 vs. 18-6 ?
