spaghetti squash seedlings - leaves turning pale!

burngirlMay 6, 2014

Hello,

This is my first attempt at growing spaghetti squash. They have been grown from seed, and are in 4 inch pots. I wonder if the leaves are turning pale yellow/white due to a nutrient deficiency? The seedlings are only about 7 weeks old so I thought the potting compost would be enough until I get them into the garden around May 12th or so. Any ideas would be much appreciated! I should mention I'm trying to garden with minimal chemical use. I was going to try out comfrey "tea" and manure as fertilisers in the veggie garden this year, as well as the base of compost we have in the beds.

Most likely a nutrient deficiency, which may or may not indicate a lack of that nutrient in the soil. The deficiency may be soil temperature related, especially with a soil that depends on the activity of the Soil Food Web to supply nutrients to the plants.
Nitrogen availability is very soil temperature dependent.

if you used fresh media to start the seed.. like you.. i would also presume it wouldnt wear out inside a few weeks ...

i would lean more toward lack of sufficient light ... on a plant that big.. indoors in that size pot ... if you do it again.. start the seed a week or two later.. so you will have a smaller plant to deal with ...

is it only the lower .... oldest leaves???: ... if so.. that leads me to low light levels ... are they under lights?? .. how does the light hit the lower leaves .. and if they are in a window .... has the sun risen in the sky.. and they arent getting as much light now????

regardless... they should be outdoors already..in full bright shade.. hardening off to temps and brighter light [perhaps into the garage at night if low temps are expected] ... a few days in bright shade.. and few days in some weak sun [morning and evening] .. and then in the ground within a week ... watching the forecasts for late frosts ...

and since you will be planting them.. i would not go dosing them with anything other than some very diluted plant food .... and then only water for the first week or two in the ground ...

germination is usually the easiest part.. lol .. its the rest where we screw it up ... and i wouldnt go all batty loving it to death.. now that you got that good looking a plant .. this far ...

get it in the ground.. and it will sort itself out.. IMHO ..

ps: i see flower buds.. properly timed out ... they would not be flowering in the house ... you may lose those flowers due to transplant shock ... dont worry about it... soon enough you will be begging friends to take excess squash away ... lol ...losing one or two early is not a problem ....

Thank you! They are hardening off now, and I plan to get them into large pots in the yard (don't have room in my beds) in the next few days. I'll just reassure myself that - hopefully - they'll sort themselves out once they're planted.
