10 Purple Urkle, 2 OG Kush 600w MH/HPS (1st timers need help)

A quick backgroud. We started off with four purple urkle. We didnt have a temp guage the first three days and the temp (which we found out when we actually got one) was about 110 F, so four are obviously not doing well. We added two more three days later, which are currently doing great. Then six days ago, we planted four more purple urkle and two og kush. The first four were planted feb 20, the second two feb 22. Then six more March 1st.

They are under a 600w MH light currently, we will switch to a 600w HPS for flowering. The light is roughly 18in away from the top canopy. Temperature hovers around 79 F, sometimes it gets up to 82 or so and then down to 62 or so in a day. temps good?

We have ample airflow with two rotating fans, and one very powerful stationary stand. The plants are constantly bristing and blowing a little in a wind. how much wind is too much?

We used Scotts premium soil along with perlite thrown in. I was told watering every 3 days was optimal and you wanted the soil to be dry in the top few inches every 3 days. Our soil seems to be holding water longer. Every 5 days seems sufficient. Suggestions?

we have a humidity meter and a ppm tester on the way. We are using sensi grow a and b, as well as VHO follar spray. B-52 by advanced nutrients in in the mail on the way.

We are running a 20.5 on 3.5 off light cycle.

We have Low Stress Trained the two older larger plants as to bring them dow to the same lever as the others, as well as attemt for a higher yield.

I will have pictures up as soon as my roomate can find the cord that attaches to the computer.

Any updates???

Okay, so it took forever and much has changed. We now have two light set ups one 600 mh in veg running 20 on 4 off and one 600 watt hpss running 12/12 flowering.

We have 10 purple urkle and 2 og kush flowering. Two of the purple urkle vegged for 4 weeks and the rest of them for 2.5 weeks.

We have 5 new 2 day old grape ape, and about 7, week-old, Jack the Ripper vegging. THe Jack the ripper got prety hot and seriously wilted, we lost several, but six bounced back really well with good growth. Im afraid of stunted yeild, but have decided to continue since they came back so strongly. The grape ape have been babied and seem to be doing well. We soaked the roots in a B-52 soultion from AN before transplany and have since watered once.

This is the flowering room. After we switched to an HPS bulb we over nuted and the a few of the plants got what we determined must be serious nute burn, the rest of them all had some damage but not too much. We topped most of the purple urkles and the two big ones were stress trained. One Og was topped, the other left alone

here are some pics of leaf damage, i cut some of the leaves that were virtually disintegrating. Can someone confirm that this is nute burn? what else could it be?

more pics of the flowering room. One of a stunted urkle next to an OG, one of an LST'd urkle, another of a topped OG

so many pictures, ty, aint got a weed thumb. Like looking at the progress...like the early flower pics, educational!

can anyone verfy this is nute burn?

Not an expert but does look like nute burn and maybe a tad bit over watering.
