1st time grow RSO

hi to all thought id join a forum for some guidance when needed . im doing my 1st ever grow not for smoking this is for my mother in law she was diagnosed with terminal brain cancer but after the shock we got searching and found Rick Simpson oil had some great results so i got all the equipment and mucked up my 1st attempt at autoflowers in a bubbler system . my mistake i hadnt done my homework but now im in DP coir in pots and not using auto flowers all is good iam 2 weeks in and im just starting to use a rooting nutriant in the right quantites but im finding a very slight yellowing of the edges on 2 of the plants and very slightly curling upjust around the edges . im using a 250w cfl for veg im wondering if this is burn from the light too close im about 3 inches away and running them 20 hours on 4 off ( i was told this was better than 18/6 ??? ) i really need this grow to work as its kinda a hope for the family to cling to even if its only a hope to see them die wouldnt be great il try upload some picks sorry for the essay
all the best

they was all looking lush green like this a few days ago

the soil was dry as i was worried about over watering as people say thats 1st mistake and it was moist in the pot still a inch under that but i watered it that day now 2 days after im getting this

heres another closer pic

Move your light up. 30cm above plant now its to close

Start nutrients soon get a ev pen give around 0.2 ec and work up

Give like a week or two then start looks a little hungry

Have you feed yet?

Looking good but 3 inches even if cfls give little heat you can burn your plants having that close

thanks for the info the only feed i started giving them in the last few days is the DP take root 1ml per litre then i ph the water after adding the take root to 6.5 i have DP A and B as feed but was told not until the 3rd week but i can see they need something so il raise the light i have a 2nd cfl 250w that i was going to add as 9 under 1 seemed a bit of a stretch as they grow but didnt want to over do it when they was small and fragile . i have a ec pen also so il begin to give them a bit of feed . from my readings which i been doing alot of would this be a nitrogen definciancy ? hence why you say start to feed ?

It not Nitrogen deficiency. That starts on lowest leaves which will turn yellow and die off to feed the newer growth.
In coco coir you need to feed them at this stage. Start with half the recommended dose. Coir doesn't have any food in it.
Once plants have established roots in coco you don't need to worry about overwatering too much. It hard to do in coco. Except when tiny plants with little roots go into big pots.

It looks like they have been too close to the light.

Edit, Your PH is wrong, its not soil, you want your ph to be from 5.8 - 6.2

Looks like heat stress.
I'm running 400 watts of cfl's and have an exhaust fan plus an in line fan and have to leave the tent doors open with the AC blowing directly into the tent to keep the temp at 80*. You have nice looking plants.

If those avitar pics are your plants I'd ignore any of your advice. Burnt, clawing, crispy leaves, you proud of that?

yeah the pic in the avatar are mine im gona upload my lastest pics after 4 days of feed only fed twice in the 4 days and today i spread the plants allowing better access and added a 300w cfl i tried to get a 250w to match but couldnt . i cant belive the difference in the size and light output of the 300 compared to the 250 ......... pics to follow . i think il start a journal of the progress may help if i start to go wrong somewhere

heres the babies now ...... feeding on a low 0.8 on the ec pen il raise it 0.2 each week till im up at the amount . also ive read use water with feed twice then just a clean water so 2 on 1 off ?
