Help me diagnose this problem. Pics attached.

Ok heres the rundown. The leaves with the spots are the first leaf set. The spots showed up pretty much from start but got a little worse this week. It is now week 3 1/2. I know it isn't heat because I have cool blue fluorescent tubes atm and the bulbs do not get hot, also it's the lower leaves. I use foxfarm grow big and am at 3/4 nutes as of last watering and will be going to full nutes next watering. Also the spots started before I ever started nutes around week 1 1/2. Should I just snip these leaves off or what. I know there is a diagnosis chart on here but I can't find it atm, probably because I'm stoned. I think this should be enough info but if I forgot anything refer to the end of the last sentence . Thanks in advance for any help.

Do you PH? and what is the npk of the foxfarm?

ah i knew I forgot something. I do ph the water to between 6.0 and 6.5. The Foxfarm is 6-4-4.

That plant is stunted. it should be bigger for 3.5 weeks.. I think it is a pH and possibly an over watering issue.. can your transplant into a 3 gallon container with a 30% perlite 70% soil mix?

this could save your arse...

Im doing lst with it. It is probably 6 1/2 inches tall if I let it stand. The pictures just make it look stunted. The soil I made myself with 40% soil, 20% cow compost, 20% perlite and 20% vermiculite.

Also I only water when soil is dry at about 3-4 inches deep. I do about 1/6 of a gallon every 4-5 days or as needed.

Here is maybe a better picture of it.



the space between the nodes is about 1 inch and at the present the 5th leaf set is emerging.

Let me know if you still think it's stunted cause I definately am here to listen and learn. I just didn't know if you could judge it better with a little more info.

i have almost the same problem on one of my plants. im growing in hydro with fox farms and am at the 4th week of flower. i cut off the affected leaves and am watching to see if any more get like that. did you bake your soil at 350 for an hour? i did that to all the soil i have my mothers in. im in central america and cant buy good foxfarms or equal soil so i figured better safe than sorry, so i baked my soil mix prior to use. good luck let me know what you find, i have a help diagnose this problem thread but nobody replied with any help yet. good luck with it. rm
