1st time grower here. Any help would be great. These are 2 weeks old.amp;nbsp;Transplanted 5 days ago in soil from germination kit.amp;nbsp; Leaves on one plant are yellow in the center. Is this Nitrogen Lockout?amp;nbsp; or maybe Iron deficiency.amp;nbsp; IMaybe light burn but the LED lights were not very close where i could feel the heat from them.amp;nbsp; I used Organic soil, Myco, Garden lime, Perlite, and earthworm castings.amp;nbsp; The first has a light tinge of the yellowness but picture 4 or last pic has the most yellow.amp;nbsp; Other two look ok.amp;nbsp; PH was running pretty high at about 7.6 or so in the soil and unsure of how to lower it as the soil is pretty wet. I am trying to wait til it dries out.amp;nbsp;amp;nbsp; Using a meter gauge and it only goes to 8 and is near there. I think i need a LED gauge to better monitor PH.amp;nbsp; So I think in short PH is to high that is causing stress and Nitrogen lockout but trying to figure out how to lower PH is soil without drowning plants or overwatering.amp;nbsp; Any help would be appreciated.amp;nbsp; Thank you!amp;nbsp; amp;nbsp;
