What do you make of these?

Got 3 Tropicana cookies flowering and three assorted strains vegging. 150w hps on flower and 300w led on veg. Growing in soil in 3gal grow bags.

The budding plants are about 7 weeks into flower and the vegging plants are about 2 months old, but growing v slowly.

Budding plants are beset with yellowing leaves and the sugar leaves are starting to get yellow as well. Vegging plants are getting brown spots and tips, even on new growth.

I seem to have trouble keeping my ph low enough, it’s always creeping up, I water with ph balanced water - low 6. I am using Orga Grow Holland notes at like half strength and only just introduced some cal mag. I am trying to get the ph down so much that now I’m worried my plants are always too moist. Have some flying insects in the vegging plants, using neem oil for this.

Ill post pics, hoping someone can give some advice on what is happening.

The scant number of fan leaves and the yellowing of the remaining ones is probably slowing your bud development, but the flowers themselves don’t look bad for all the problems your foliage is having.

Given the fact you’re seven weeks into flower, I think your best approach at this point is to “do no harm” — in other words, avoid any extreme remedies. The reality is you’re not going to grow any more fan leaves at this point, so preserve what you’ve got. Don’t over water, which is bound to be more problematic than the pH.

There are pretty regular debates on here about whether it’s even worthwhile to pH when growing in soil. The verdict seems to be that it’s effective in preventing lockout when using chelated nutrients. Generally, though, I don’t bother with pHing my water because I use organic nutes and haven’t run into problems.

In any case, overwatering could be depleting the nutrients in the soil, which may account for the yellowing. However, this doesn’t mean you should overcorrect with more nutrients, which would risk toxicity.

So basically your best bet is to avoid extremes until the colas are ready to harvest. I’d ballpark it as another month until harvest based on your pistils still being fresh and eager for pollen.

All in all, though, you should end up with some decent bud, which I’d consider successful for a first grow. Good job!

If you topdress with diamataceous earth and two inches of sand or hydracorn those little buggers will die off, they don't climb or burrow up through this, there are chemicals too but this works for me, even sand or hydracorn which is expensive, alone will work.I use hydracorn on bottom and top of my pots, 2 inches or so, mainly for those root eaters, no bugs since practicing this method. Much luck!

Cheers for the advice. I think I’ll definitely just let these ones ride it out and then do better next round. I thought they were a little closer to harvest than that, lots of milky trichomes, nothing amber yet though. The pistils have started going orange and curling up in the last few days. My plan was to basically flush them from here on out, maybe with some molasses in the water. Then harvest.

Yeah, had some dt earth but my dog destroyed the bag, I’ll get some more. I’ve never heard of hydra corn, I’ll look into it.
Thanks to everyone who replied, I appreciate the advice!

I've been fighting gnats myself, started top dressing pots with sand also, kept the little fuckers from going through the tops but then i noticed them going into drain holes in bottom of pots, so now im switching to fabric pots, top dressing with sand
 
How many plants are you trying to flower under a 150 wattHPS?
I’ve got 3 under the 150w hps flowering in a 2x2x4 tent and 3 under a 300w led vegging. When my flowering plants are done in a couple weeks, I’m going to combine the lights and use the led and the hps when switching my vegging plants to flower. That should increase my yield right? I think I’ll be lucky to end up getting an oz off my 3 budding plants atm.
 
Here is an updated photo of my flowering plants.

You can see the yellowing has only gotten worse and I barely have a green fan leaf to speak of. I have noticed that I’ve had almost no extra bud growth in the last week or so. I’m just hoping that they stay alive long enough to ripen and get chopped. I’m probably at about 50/50 milky and clear. Still no amber trichs, only some amber pistils.

At this stage should I just be flushing and preparing to harvest in case they turn south? Or should I try and give them some food and then flush? I’ve done nothing for a week, mostly because I needed that soil to dry out a bunch.

Here is a pic of my vegging plants. They have recovered a bunch from overwatering, but the soil is still too damp to give them anything more. The 2 fat leafed ones I’m trying to grow using nebulas manifold technique, but I snapped three cops on one by being a bit rough, I’ll wait to see the result of the one good manifold I did, but it seems like a pain in the ass. Also are tomato rings worth using as supports or do you find they just get in the way?

Since you are new here
I must ask

What web site were you on previously that encouraged flushing and let you get that plant so far gone?

And Welcome to RIU :leaf:

Seems like most sites tell you to flush, it even says it on the nutrient guide on my nutes. Big part of the problem is that I thought they were further a long than they were. I thought they were much closer to harvest, like a week away rather than a month away, not sure why I thought that. I had also flushed it previously because I thought I had caused nutrient lock out, that’s what I thought was causing the yellowing early on, but maybe I was under feeding it the whole time. I also have read in places that yellowing leaves during the flowering stage is not a problem, so I didn’t really give it much heed until it started to become pretty drastic.

Well that sucks

I would consider choosing a single site and make a grow journal/diary

Folks are always offering varying opinions but if documented and followed along someone will always call out any misinformation

Best of luck on your decision

The ph rises meaning the plant and soil microbes are using the nutrients. It what happens, aslong as it stays between your 6-7 in soil youl be fine with the ph part. Just try to keep your plants healthy.
