can anyone tell me whats going on with these two all the rest look fine the one on the left is about three weeks old on 18/6 mh hard to see but bottom two rows have yellowed severely other looks like nute burn but im not sure

I am new at growing too, and im still finding it quite hard to distinguish between nute burn and deficiency BUT I do know a few things. If the bottom leaves are the ones yellowing, and the yellow is sorta spreading upwards, its probably a nitrogen deficiency. However, if you dont want to take my word for it you can always flush them out really good, and if the yellowing continues you know it is a deficiency and not a burn. Hope that helps. lol

It's hard to tell from your pics, especially the one on the right. If you overfeed your plants, the signs of nute burn are pretty obvious. The leaves will show the nute burn on all the tips.

If your problem comes from overwatering, you may not want to flush your plants. If your soil does not drain well and you have been watering pretty frequently, I would let them dry out. Then water well with distilled water to clean out the potential salt built up in the soil. There really are so many possibilities, that it's hard to guess without knowing everything that you have been doing to them. Sometimes when a plant gives a problem, it's better to do less than more. Good Luck

to me it seems like you have over watered...on the pic on the left looks like the soil is REALLY wet...let it drymore before watering again, water it with about a cup of water around the base about everyother day or wait till the soil is completly dry underneath too. add your nutes to the water so when you water it will soak into the soil
