10 x seedlings are 16 days old, planted in seedling/ cutting compost watered every 2-3 days under 55w of floro's. 5 strawberry cheesel & 5 hazolope.
Problem started about 3 days back when I think I overwatered the hazolopes, the watering mix is only bottled water and rhizotonic with a lil molasses, havent checked pH as I ususally don't need to adjust in soil- could be another issue. Hadn't checked roots @ that stage and assumed after 10/11 days growing in cups the root system could tolerate watering until run off occurred. Maybe I am wrong but the day after they didn't look so clever, and a couple days after that they started showing signs of a def in the oldest leaves.
I have let the hazolopes dry out thoroughly and will water lightly again today.
The same defs are now starting to appear on the strawberry cheesel which I also gave a good watering a few days back.
There's definitely no pests insects at all, so I a few possible scenarios.....
1. I have over watered both sets of seedlings (doh!) and defs are showing slowly?
2. The seedling compost has been depleted of mg/ ca or something in the 16 days they've been in there as there are similar/same defs on 2 different strains.
3. pH has been too high (will check pH later today when I get my new pen) and as cups were fairly heavily watered this has locked out ca/ mg other element
4. Bottled water with low ca/ mg content? (would have assumed compost/ soil had sufficient amount for seedlings?)
Help with identifying def, how to rectify and possible cause greatly appreciated!!! Don't usually have issue like this and it's doing my head in now.
