Fresh to growing sensi, keeping it simple but help wanted and already had silly probs

Fresh to the adventure and art of growin but think I got a good chance for a lil bit at least.
got a small fan and some reflective paper.
in pots of just compost.
lights-4 hps white, 250 wat
had bit of a silly start but now have: 1 white siberian, 1 humbolt x jack33, 1 ufo Haze and soon 2 ryders for a quick small yield.
All started different times, hence different growth stages.

Lets see how it goes, everyones comments and help is always gona be appriciated..

Peace, Live free

As you can see in pics plants were burnt cos i went away for a few days and while they grew they obviously got too close to bulbs and so moved them lower down!!
nicest plant, also the best at withstanding crap is the siberian, nice.

that first pic looks nice and leafy excellent start

Sexy plants man, wish I could grow inside!

Basically some silliness happened and the plants all got so over fed that they were close to utter death.
Flushed em completely with tears and proper water too of course haha but now their drying and under the light.
Fuck.close call..
No pics as its nt even worth seeing..hopefully some good recovery
