New problems after resolving problem 1 week ago (Pics)

Hello,

I posted on this forum about a week or so ago about how my plants leaves were having problems. From the pics people informed me that my plants were having PH lockout so I flushed my medium and for a few days the plants recovered. However, either the same problem or a new problem has come back with a vengeance. If you all could give me some further diagnosis I would much appreciate it as I am completely lost at this point.



Equipment:
.1) Type and wattage of lights ///// 400w MH/HPS, 3ft 32x2 T8
.2) Distance from tops? //// 8 in
.3) Reflector type? Cooltube
.4) Is there a consistent fresh air supply?//// YES
.5) Do you have an exhaust fan and a circulation fan? /////Yes
.6) What are the bulb wattages, kelvin ratings, and schedule? 400w, 12/12


medium:
.7) Specific brand and type of soil, ////FFOF w/25% perilite added and 1 cup of dolomite lyme
.8) Size of container.///// 3 GALL
.9) Did you use peat pucks (or similar) to root clones or germinate seedlings? Clones grown in aeroponic cloner.


nutrients and water:
10) Source of water? ///// Tapwater that I let stand 24hrs + filled with dolomite lyme
11) Method of checking water ph.//// PH PEN
12) Method of adjusting water ph. Dolomite lyme
14) How often are you watering between feedings, and how much per watering? ///// water when pots light (usually 2 days) Nutes ever 3 waterings
15) Any additives or tea's? ///// 1 tbs molasses per gallon on no nute days
16) Are your ph levels stable, or do they fluctuate?
17) What is your ingoing water's ph? ...your runoff ph? in 7.5 out 6.5
18) Do you foliar feed? If so, with what, how often, and at what time do you spray? ///// No


growroom:
19) Indoors or outdoors? //// Indoors
20) What size of closet, room or hut? ///// 3X3X7 GROW TENT
21) What are the temps and humidity levels while lights are on? ...With lights off? ON +/-80/40% OFF 72/50%
22) Have you seen signs of insects in the growroom? //// No


strain:
23) What strain are you growing? Nirvana Papaya /// Nirvana Northern Lights
24) From seeds or clones? ////Seed
25) Is this an autoflower strain? ////// No


The first 3 pics are from the NL and the 4th pic is from my Papaya

Should have only about 3 tbsp lime for 3 gallons.
Try watering with PH of 6.5 or so for a couple times and check runoff then. Don't expect runoff to change right away.

You did all that writing but I didn't see what nutes or how much you given them? Maybe I missed it:)
I use ffof straight out of da bag and they're just as perky as can be almost too perky it scares
me! Go Blue.....

looks like you got calcium deficiency,phosphorus deficiency and looking like you're heading for a nute lockout.PH at 6.5 works for both but you may want to foliar feed 1/4-1/2 strength nutes to fix the problem.And 72 degrees may be too cold with lights off which is the problem im having now which also causes lockouts of some nutes.

Definitely too much lime. It's 1 TBS(tablespoon) per gallon of soil. Some say as low as 2 tsp(teaspoons) per gal.

Those are great day/night temps so no issues there.

Be sure to switch to smart or air pots in future.

It looks like not only is mag locked out but they look burnt. You have clawing on top as well as canoeing down(I'm guessing too much N or other nutes and overwatering)

Is this 7.5 pH watering in 6.5 out for runoff been going on a while? By this point, and long before it for me, by week 4 of veg I'm able to control my pH at 6.5 by feeding at 6.5. Are you also feeding 7.5 in when using nutes?

I've never heard of your nutes and I always feed every other watering
Don't worry about da runoff it isn't accurate my runoff ph is 5.4-5.9
with the ppms over the limit of the meter of 1990 ppms but ffof is known
to not to be consistent !~

A cup of lime for 3 gallons:shock: So consensus is too high pH locking up nutes..whatever they are.
