Nute deficiency?

[Noobiegrow]

I transplanted about a week ago into ffof in 5 gal pots and put them outside, haven't fed them yet just watered. They are about a month old from seed and I'm starting to see leaves on the top and middle of the plant on the outer edges turning light green. Help please

Hi @Noobiegrow it appears it could be the start of a mag deficiency but it's hard to tell for sure. I see your plants are outside. Has there been a lot of rain?

What are your watering practices like?

The new growth always starts of light green and will darken as it ages and grows. FFoF is hot and 1-2 weeks in the soil has what yr plant needs to gently get there. I don’t see any immediate issues so I’d say just water for another 2 weeks before introducing a light feed and working that up to max mfg recommendations. And with water use cal mag, even if on tap water. I water with cal mag every time . Has light nitrogen in it so it keeps her going

Yes they are outside it hasn't rained too much and I check the weather to make sure if they do need watered that it's not going to rain that day or within a couple days. Haven't fed with any nutes yet

Yeah I haven't used any nutes yet and that what's I keep hearing is to use CalMag
