The lower sets of leaves have started to turn yellow, some of the tips of leaves have curled up and are crispy and brown. also the stems of the leaves are turning purple. What is this and how do I fix it.

I have only given then a small amount of nutrients and my PH is good.

Looks overwatered a heck, try spreading out your watering frequencies to a couple days apart, dry cycles are benificial and key.

I would have started those with 6500k CFL's so you can get some of that blue spectrum. Then I would have added the HPS a week before flowering. Im using CFL's and I have way more foilage then that.

have 5 plants but only 3 are female and yes still in veg.
ya k good to know because I had them under CFL’s but put them under the HPS after like 2-3 weeks.

So you only think its over watering?
Because I was looking on the internet and it said that it could be a Sulfate deficiency ??

Looks like alot of problems there. Lot of stretching did you keep thecfl or flors right on top of the seedlings looks like light was to far. Is temp 75-80 tops? Have a fan blowing on plants to circulate air? why is it so red in the picture?Pots might be little small also.Whats the ph and are you adding nutes or no nutes? water ph?

ya ill put the flors light right above the plants next time!! The tem is 75 (but before I moved the grow room the temp did get up to 90 so idono how long it take them to recover from that or did that damage them for life?) its red from the shity camera and idono it’s a HPS light?? I will go get some new bigger pots. PH is 6.7-6.8. and yes iv added nutes. Im using 20-20-20

if you still have issues with stretching try Bonide Tomato Set Spray, it will initiate more lateral branching and keep the plant bushy even under hps. Kelp extract also helps.
