hi guys, posted a couple times about this and i'm trying to pin point my problem, before i get into details here's my grow info:
-room temp 78-84F 40% room humidity
-sealed room 1650 ppm co2 enrichment
-i'm using 50/50 coco/perlite (small cup -> 1 gal pot -> 2 gal smart pot)
vegging in a tent under a 8 bulb T5, flowering under 1000w hps
nutrients i'm using h3ad 6/9 gh flora 1/2 tsp epsom per gal at 5.6-6.2 pH, i use some great white for mycos, when i flower i use 5ml per gal floranectar for my sweetner, humic/fulvic acid, an big bud and super natural bud blaster for my bloom boosters (some say too much stuff but 've used same mix with great success before at a different garden), i'm topping at 2.4 ec (1200 ppm .5 tds factor)
-flooding ebb flow 4x4 trays, 9 plants per tray
-1500w of hps lightning per tray, flooding twice a day lights on and off for 10minutes
-gdp indica strain very short, topped and trained w/ scrog screen
ok, so basically i'm vegging in the tent for about a month from cup to 1 gal then to 2 gal, and throwing them under 1000w in my flowering room, first problem i had was i had yellowing i think due to the plants not hardening off and the leaves would yellow and die and new growth would come out (i'm going to raise the lights much higher, and do some premeasures to harden them off with a 600w in the tent), but my last run, after they healed from the light stress from the 1000w they got green again and i flipped them but after i flipped them all the fan leaves on my plants started yellowing badly and i thought maybe they would get better (they looked hungry) but they just got worst and the leaves started dying off, im trying to determine if my problem is:
-plants are not getting enough nutrients, or plants are getting overfed
-light stress continued after they healed
-minor alagae buildup causing pH to not stablize causing nutrient def/lockout
-roots in pot have outgrown the pot causing buds to suck all the nutrients from fan leaves
-nutrient defiency ranging from N def, Mg def, and even P def with so many symptoms i'm thinking its a pH problem (but i'm trying to keep pH at around 5.8 in the rootzone)
the buds themselves look ok, but i'm guessing they would've got much bigger, and im thinking its going to cause me problems my last few weeks of flowering when they're suppose to be getting yellow, effecting my yield
thanks for reading my long post and hopefully i can get some good advice/input on what i can do to prevent this from happening again.
