To any of you who grew durban poison or have experience with growing sativas, I could really use your help. I'm germinating some DP and blueberry seeds right now and the DP is giving me major problems. I started 5 DP seeds and only two actually germinated while all 5 of the BB seeds germinated. Out of the two DP seedlings, one toppled over and died. When I woke up this morning, the second DP toppled over. The BB's are doing great. What's the deal? I'm using the same conditions for each type of plant.
I soaked grow cubes in distilled water and placed all the seeds in them. It's now been a week and the other three seeds still haven't popped up, although one of the seeds broke open 3 days ago. The tap roots came out of the cubes, so I placed them in solo cups with a 4:1 mixture of soil and vermiculite. I watered them after the transplant. The DP stems just thinned out and the plants fell over. I propped up the DP that fell over this morning and added some more soil so that more of the stem was below ground. The leaves still look really good (green and healthy), but the stem is shriveled. I didn't add any nutes, I'm using fluorescent lights, and the plants are about 2 inches from the lights.
Any suggestions will be greatly appreciated because the other 5 seeds have been in the grow cubes for 2 days now. If any of them even decide to pop up, I don't want to repeat this experience and end up with no DP plants to enjoy during harvest.
