4x3x5 tent mykar and vents. 300 watt led mars hydro. Lg-96x5. Max power 480w.power consumption-210w. Bloom and growth on off switch. Four white widow females bought online. Middle plant either kush or strawberry kush total 5. Trying to get balance of yield and qaulity in my space. Limited space but not trying to go big and expensive just yet. Dyna grow foliage pro 9-3-6 and just couple stops in a 1.5 liter bottle. Whites were transfered in coconut husk about week and few days ago. Kush is about month and a half. Plan is scrog once I get kush teenage to about 2 1/2 feet or so and install screen .get more light penatration to guts of plants. Was doing great with teenage kush untile I underwated yesterday was drooping and fan leaves yellowed. White widow over watered when in coconut husk pot and almost lost em but dried out and ended up recuperating. Also once get screen need suggestions on how many and wattage as well as type lights to add for flower. Plan on using veg and flower on led main panel for last month and adding extra lights for flower thinking for yield since added total 5 plants in 4 liter pots. Advise on pot size in relation to over all soacd 5ft night. Best I can do with apt. What do you think?...

Just an opinion, but I think you're still thinking too big for a first grow, which is likely why you over watered one and under watered the other.

If you're growing for personal consumption, why not start with one plant and take it all the way? This will give you a feel for your grow area and what growing entails.

Have a look at my sig below, this is a closet grow I setup for a friend which is exactly the same size as yours. Two plants max, 5g buckets.

Heed the advice above! I believe you may be in over your head with 5 plants... Scrogging takes up a good amount of floor space and you have 5 plants in the same area... I have 4 in a 4x4x7 and it's crowded without a scrog...
