Guide for Diagnosing Plant Problems

Hey zen, yes the ph has a lot to do with it and can cause problems. Along with to much salt. If you are using canna stuff you should not have to worry about the ph levels to much. They have stuff in it to help control the level and keep it in the range it is supposed to be. I just switched to canna stuff my self and have been happy with it. Foxfarm is also good. I always use bottled water or tap that has sat at least over night. But I give my house plants strait out of the tap and also any plants outside and they seen to do fine. But I don't want to take a chance on killing off any good bacteria that I have put in. I believe that both Canna and Foxfarm have them in their soil mixes too. And Cal-mag is a product not a deficiency. Although you can have a calcium or magnesium deficiency. That depends on what your water source is. It's good to know what you are using, they allow for the water being used to have some of the micro nutes in it when they make the nutes. But not all of then.

For anyone that hasn't seen it this is a good problem guide http://www.icmag.com/ic/showthread.php?t=11688

One week old seedlings they were fine a day ago, now have wilted wavey leaves on one and leaves drooping and curling under on others, using MG garden soil with the self release ferts, and very carefull to not over water, only watering every other day or so. temps and humidity does fluctuate a lot, 65-95 F and 45-65% humidity. can send pics if needed.

the seedling probly cant handle the slow release ferts get rid of that soil and find a seedling mix or at least a good soil with out slow release ferts

Pics are always best. If you want to post a problem it can be a lot easier to diagnose if you post pics. Are the pots dry and light in weight by the time you water them? If you can get the heat down it would help.

Post some pics if you can. Sometimes they can have that many leaves from what I've seen.

Hey guys going for a grow and my plant is showing some bad signs.
Basically i was using the wrong nutes for the first couple of weeks and some of the leaves had gone browny and started to curl. since then i've changed to a proper aqua nute set and the plant has shot up pretty fast
i'm worried though cos the roots are a little brown, the older leaves that were damaged at first have gotten worse and the new leaves have gone slightly pale and have faint yellow spots on them.

The nutes im using are canadian express; got 3 chems head masta (for flowering), bio balancer and ultimate indoor.
They're specially designed for aqua so my DWC should have no trouble with them.
currently im vegging (3 weeks from seed) with the ultimate indoor and bio balancer.
i've checked all the measurements and the nutes are at the right concentration so it's not nute burn.

i just need to know if im missing anything specific in terms of chems and if i should be adding some more supplements to them. also would it be worth doing a bit of pruning of the older more damaged leaves?

here are he pictures of my plant and set up:

Sorry to Jump in on u guys all the sudden but my plant is hooking. Like literally a hook / fishing hook style. Check it out

What does this mean?? V

Nitrogen excess, possible root zone issue with cold temperature water.

So cold water will make the leaves hook????

I'm not sure because I've never tried it myself but that's what I hear. You want your water to be somewhere around or above reasonable room temperature. 78 degrees or so. Watering with 50 degree solution could, maybe, possibly, cause an issue like this. It is more likely that it is Nitrogen toxicity.

Could stress the plant to herm??????

now that i am home i am able to post some better pics of the curling thanks for the patience man also possible hermie. but i have not seen any pollen what so ever anywhere..... so yea some advice would be wunderbar..


the small small plant next to the purple flo is a clone of the same plant. no hermie or pollination there either. so what is the explanation for the god damned nanas!!!!!!!!



IVE LEARNED MY LESSON NOT TO WASTE ALL THAT TIME ON ONE FUCKING PLANT....... POO!!!

where'd the seeds come from? feminized? shoddy feminized seeds will give you hermies. or even a clone from a friend with shoddy fem seeds. a light too close to one bud, stressed that one part of the plant out. that's nothing big to stress over. just dip your fingers in water and pinch that part of the plant put it into a cup of water and dispose. basically you're trying to neutralize the capability of the pollen to become airborne. good luck with that.

heres the facts, soil grow, miracle grow, strains are white dwarf auto, and himalayan blue diesel auto. both broke soil on the 7th of nov. in a stealth mini fridge setup with 4 x 42 watt 2700k cfl's. schedule has been 20/4. just started liquid karma and grandmas molasses about 3 days ago, 1/4 strength, and only uses it every third watering. these yellow spots came up yesterday morning, this pic was taken last night. now the very very tips of the brand new top leaves seem to have a little yellowing on the very tips, please help.

Looks like pH spotting to me. Probably the issue being that you haven't included any pH info and because you're using Miracle Grow.

honestly, i didnt have the 60 bucks for a quality ph meter. i have been using just straight store bought distilled water. i introduced the seedling dose of 5ml of liquid karma and a the same amount of molasses. but the Blue himalayan is problem free. and i know miracle grow is frowned upon, but as this is my first grow, i didnt wanna blow money on ocean forest or something similar and just eff it up. plus, i have a very good friend, and grower of 10 plus years or just said for the first grow just do miracle grow and dont worry about a little nitro burn, but he said thats not what this is so now im stumped. is there a quick somewhat cheap way to test ph? and fix? i have pool testing strips, but dont know how i would adjust. thanks for the info please continue to help if you can crash. much appreciated

Distilled water is all bad. You want reverse osmosis water. Spring water is fine also as it'll have some minerals too.

You need to keep an eye on the pH. You're probably going to be within range with that mixture but I'm not a major proponent of molasses so I'm not sure where that'd drift the pH to.

Getting off the distilled water will help.

It's good that you help us with identifying the symptoms of certain problems. Thanks a lot! But the real question is what do you do for curing the problem.
