Ive got three just started like 16 days ago in happy frog and they look healthy. @Frescal
How are you checking the pH of your water? You might want to consider calibrating your meter. The only thing left to check is pH and possibly chlorine if you are on municipal water?
Happy Frog is an enriched soils and i’m thinking at the age of your plants it’s just a tad early for adding additional nutrients to the water.
Do you have a TDS meter to check the water and runoff?
We just covered this in another thread @AMUSED2DEATH but as we learned it is a mix but the forest products and enrichments makes it a soil. Also has dolomite lime in it but it wouldn’t be a bad thing to double check it.
Glass of pH 6.5 water and tablespoon of soil. Wait 5 minutes and check pH of water soil mix.
I have a bag of happy frog here too and I will test mine later to be sure as well.
ok, sounds good. Most of us wait till the plants have about 4-5 nodes (not counting the Cotyledons and the next single leaves) before giving nutrients.
Do you have calibration fluid to double check your pH meter?
Your having an early stage of phosphorus deficiency as well as cal Mag deficient. You can tell by how the leaves are yellow (calcium ) and you can also tell by how the leaves curl at the tips @Frescal and @bob31 for future reference.
Give them a light feeding and they should bounce back
