Help me Diagnose

Hello, im having an issue with my plants & seems to be worse on 1 particular strain.

Some info for you 1st then pics.

Type of setup & equip ::

Water : Tap, normally ph of 8. I bring it down to 6.5-7 and let it sit for 2-3 days before use.

Lighting : 2x 600w

Nutes : FF Big Bloom, Liquid Karma, B1 Thrive, Humboldts Gravity & Snow Storm, Root Excelerator, Silica Blast, FF Root Drench.. I do not feed all at once of course. Each has their own time to go in the soil.

PH Meter : Yes, I have not been checking run off.

Co2 : No, has outside freshair though its indoors.

Ok well, the Larger older fan leaves at the bottom of my plants are getting these Yellow spots around the edges and then turns into dead brown spots, the tips may curl upward on some. and its slowly moving up the plants.

I will post better pics tonight from my other plants where its ALOT WORSE. Also, the 1st TWO weeks of watering I was not PHing my TAP.. so that may have caused issues but since then.. I PH it.. any advice

you don't always have the nicest of attitudes-

on this board.

and your posts are not always on topic ^

ok-

how's your watering? they look a little over watered.
with a little nute burn due to rapid intake from flooding of the root zone with 6.5 water.

then they look like they were hot once or twice.

Yes im thinking the 1st two weeks caused a PH imbalance.. but its continuing. Can it be the TAP water? even though i let it sit.

Water should be fine even from tap if you let it sit for 24 hr, unless your tap comes from well water...

well-

when the root zone experiences low ph water, it thinks it's rain.
the plant then goes into hyperdrive to try and wick that water through transpiration. in that is the great secret.

if your pots aren't drying out then they are stuck in this "suck" mode all the time. i water through with well water and it's fine.
i do ph it down to get the plant sucking.the trick is to get the nutes right, so as not to burn the plant. keep in mind, when the plant are doing this, differences in genetics will require different nutrient levels.

read some of uncle ben and riddleme's threads.

nah not well.. Hmm. I guess when i Post the Full Pics of the Worst plant.. youll all get a better idea..

i also have used city water-

with great results. it's actually how i found this technique. it was 5.8 out of the tap.

looks like over watering to me.

you can hold back on watering until your plants start to wilt and it really doesn't hurt them.

Damnit.. (watered this morning).. would the over watering cause the Light yellowing around the edges of lower fans?.. Not happening to the Sugar leafs or bud.. just fans.

yes, it starts from the bottom up, hitting the fan leaves first.

Good to know, I know for a fact I keep them more moist than I should. its just their in 2-3gal grow bags, plants are like 4ft tall.. so I was afraid of them drying out too quick due to their size.

it is harder to fix over watering then it is to fix under watering.


KISS

get in the habit of lifting your pots-

it will help you to get the feel of what the soil looks like at different moisture saturations.

then let them dry out. when the plants are thirsty they will show you. they look like they're frowning.

water 'em back up. make sure that you give them enough at this point. i water and feed to the point of substantial runoff.

I already do that, but due to the plants being Huge 4 footers... a 2-3gal bag is hard to judge.. since the plants so heavy

I keep my grow lights on 24/7 and have a separate room in house as a permenant dark room, Switching plants every 12 hours allows me to double the ammount i can have.. Thus, I literally Pick up each plant twice a day..

i think u might be a little low on the P. i have the same shit on my outdoor plants n when i fed it it stopped progressing.
