i have 8 clones of grand daddy purple...they have been growing fine but developed small little spots on mostly only the top leafs the leafs that started with the clones also have a little yellow and 1 of the plants the leaf looks like it shank and got very brittle

set up

using 4 100 watt fluorescent lights
regular potting soil w/ osmocote smart release plant food says last up to 4 months
its 19-6-12 put that in the soil about 3-4 weeks prior to planting

i water every 2-3 days
watering method is i stick my finger in the soil when its dry about 2 inches deep i water

air i installed a bathroom fart fan for exhaust and just bought a tower fan today that i will be putting in tomorrow

i have a ph meter but i dont think the thing works i says its 6.8 ph gonna be getting a digitail meter in a couple days and i will update with the ph

temp runs 65-75 dergrees and humidity is around 35%

lights are on 21/3

the 8 plants are in veg clones where bought on march 23 and are about 9-12 inches tall

pictures included
#1 clone leaves that where cut most of them look like this


#2 the leaf that wilted
this is the only leaf like it


#3 alot of the top leaves have these spots this is the worst out of the 8
a couple spots on lower leafs maybe 1 or 2 spots not like this

#4 same thing sorry its a little blurry

Your humidity is pretty low, try 45-50%, sounds & looks like a ventilation issue. R they getting fresh air & is the expelled air being properly vented from the grow area?bongsmilie

i open the door about twice a day works been very busy for the last couple of days so im just getting a fan in there it would be in but i have to cut the bottom and mount it and im trying to think of a good way i can do that....i will get it in tonight or tomorrow.....air being vented is by a bathroom fan cut into the celling its is 50 cfm and is on about 20-22 hours a day
how would i rasie the humidity by about 10%

Well once u get a supply of fresh air entering the grow area the humidity will become higher, or fluctuate until u get the right amount of fresh air coming in, and the right amount going out.
This may take some adjusting to get the ideal temp/humidity, u may even have to leave the door slightly open with a pedestal fan blowing in, just trial & error!bongsmilie
Once u get the correct balance of intake(fresh air) & outlet(expelled gases) u will find it easier to regulate the temp/humidity, but u need more supplies, like flexible ducting & fans to suit!
Plus I don't know what sort of temp's u experience in your part of the world which would contribute to the regulation of temp/humidity.
As I said, trial & error, u can do it, good luck:joint::bigjoint:bongsmilie

You have a nute problem.

I don't like using slow release ferts in the soil as it makes it impossible to control the nute levels.
Young plants like this need to be introduced to ferts gradually.

Personally - I would re plant in regular good potting soil - then add liquid nutes as needed.
