2nd Indoor grow leaf advice.

Hi everyone, so i have had this indoor grow going for 20 days now, dont look at size difference, they were planted at different times,

These are the nutes im using curently im using 0.5 ml per litre of water (sorry im from europe)




The light is a 400 Hps hanging at around 40 cm of the plants





Also there are 3 deifferent strains:

Early skunk, bud star and bagseed
Im just having problems with the early skunk (mostly) where there are yellowing spots on the leafs, now according to jorge cervantes'es book
it would be a magnesium defiency problem,

also the new young leafs are very closed up so to say.
I have also added a picture of the temp/humid. Oh and btw they are under 24 hour light and i keep water ph around 6



All comments are welcome

PS: This is they're 20th day from starting to germinate (the big 1ns)

looks like you;re doing everything right - just keep doing what you;ve been doing

Well ive red a lot in these forums and the book + a lot of friends of mine grow outdoor so i combine all that into my idea, but my question still remains about the yellowing spots on the leafs.

anybody had this problem

could barely see the spots in the pictures but who am i to challenge jorge cervantes? looks like either a micronutrient deficiency or maybe ph?
